FAQs
the ‘tiny house’ concept
-
A tiny house is a small, fully-functional home that’s been carefully designed to make the most of limited space. Typically under 40m², they include all the essentials you’d expect… living area, kitchen, bathroom and sleeping space, just in a more compact, efficient layout.
Tiny houses are often built with sustainability in mind, using fewer materials, lower energy, and a lighter footprint on the planet. They can be permanent homes, transitional spaces, or flexible accommodation for work, leisure, or travel.
-
These terms are often used interchangeably, but they can mean slightly different things depending on who you ask:
Tiny homes usually describe the smallest homes, often built on trailers or chassis so they can be legally classified as caravans. They typically range from 15–25m² and are designed for maximum efficiency and mobility.
Micro homes are a step up in size and permanence. They are usually fixed to the ground (for example on ground screws or shallow foundations) and can range from 25–40m². They’re still compact, but often include more conventional layouts for longer-term living.
Compact homes is a broader term sometimes used by local authorities and developers. These can be up to 50m² or more, often as part of dedicated housing schemes or small plot allocations (for example, Teignbridge Council has allocated around 300 plots for “compact homes”). They’re generally aimed at creating affordable, small-scale housing solutions.
At Wudl, we design across all three categories, from the most mobile tiny homes, through to more permanent micro and compact homes. The right choice depends on your site, planning requirements, and how you intend to use the building.
-
Tiny houses are still relatively uncommon in the UK, but interest is growing, especially as people look for more affordable, flexible and sustainable ways of living. Planning rules and housing culture here have meant they haven’t taken off quite as quickly as in other countries.
In places like the Netherlands, tiny houses are much more established, with dedicated communities and support from local councils. A few examples worth exploring:
Minitopia – an innovative Dutch project creating experimental, small-scale neighbourhoods.
Tiny House Nederland – a nationwide network promoting tiny house living.
TinyFindy – a Dutch marketplace for tiny houses and plots.
Almere Tiny Houses – one of the first official tiny house communities in the country.
land & planning
-
That depends on both the type of structure and, more importantly, how it’s used.
If a tiny home is occupied as a self-contained dwelling (i.e. someone living there full-time with their own kitchen and bathroom), then planning permission is almost always required, even if the unit is built on a chassis and meets the legal definition of a caravan.
If the unit is used as an ancillary space, for example as a garden annexe, studio, or additional family accommodation that remains part of the main household, planning may not always be required. In some cases, caravans can be placed within the curtilage of a dwelling without separate permission, and certain fixed outbuildings can fall under Permitted Development rights if they meet height and siting rules.
Because this is a complex area, we’ve prepared a planning matrix that sets out the most common scenarios (garden annexes, caravan parks, rural land, etc.) and highlights when planning is, or isn’t, usually required.
-
Most of the people who come to us are looking to place a tiny home on land they already own — often in a garden, alongside an existing property, or on small plots of land they’ve acquired. That’s the simplest and most common route.
At the moment, we don’t directly sell land or building plots. However, for those exploring dedicated small home sites, we are increasingly involved in Custom Build projects where serviced plots with planning permission are sold to individual homeowners.
If you’re actively searching for land, these resources may help:
Plotfinder - from the publishers of Homebuilding & Renovating magazine
Perfect Plot - a family-run land retailer
Rightmove - select “land” under “Property type” on their search page
It’s also worth speaking directly with local estate agents, as they sometimes know of vacant land, outbuildings, or garden plots that could be suitable for redevelopment.
If you’d like advice on whether your garden or land might be suitable for a tiny home, just get in touch… we’ll be happy to talk it through.
-
Yes, whether it’s a garden plot, back land, or a small piece of land you already own, we can help explore what’s possible. Our main focus is designing and supplying high-quality, modular tiny and micro homes, but we can also support landowners with feasibility studies, planning advice, and site appraisals.
For some people, that means a single home in their garden for a family member or as a downsizing option. For others, it might be developing a site for several compact homes or even a small Custom Build project. Our off-site building system is flexible enough to adapt to different planning contexts, though each project still needs to comply with local policies and regulations.
A tiny home can also be a simple way to unlock the value of land that might otherwise be overlooked, turning an underused corner of a garden, or a small, awkward plot, into high-quality living space.
There’s a growing demand for sustainable, small-scale housing, and with the right approach, your land could be part of the solution.
If you’d like to explore the potential of your site, we’d be happy to start the conversation.
customised design & options
-
Yes, our system is ideal for creating granny annexes and garden homes that provide extra living space for family members. These can be designed as permanent extensions to your home, or as relocatable units that fall under the Caravan Sites Act (“Caravan Act”), depending on your needs and planning situation.
There are two main routes:
Building Regulations compliant: we can design an annexe that meets full UK Building Regulations. In some cases this may fall under Permitted Development rights, meaning you don’t always need full planning approval.
Mobile home route: if the annexe is classed as a mobile home, it falls under the Caravan Act and BS 3632:2023 (the residential park home specification). This can simplify approvals and may also bring VAT advantages, making it a quicker and more cost-effective solution.
Key facts under the Caravan Act:
Must be transportable (in one or two sections).
Max dimensions: 20 m long × 6.8 m wide × 3.05 m high (internal).
Must remain ancillary to the main house (used by family, not sold or rented as a separate dwelling).
Some councils may still request a lawful development certificate, even if full planning isn’t needed.
Why choose our annexes?
High-quality design, with robust insulation for year-round comfort.
Options for cladding, finishes, and layout so it feels like a true home.
Cost guide: from around £30,000 for supply-only kits, to £65,000+ for a fully fitted, one-bedroom annexe. Most builds typically fall between £60,000–£120,000 depending on size, spec, and site conditions.
Because our system is modular, these annexes can also be adapted into tiny homes, micro homes, or compact units — giving you flexibility as family needs change over time.
-
Our focus here is on tiny, micro and compact homes — but the building system we use is very versatile. Because it’s modular, we can adapt the same “building blocks” into all kinds of designs, whether that’s a stand-alone home, a cluster of community housing, or even small studios and workspaces.
There are, of course, limits — we’re not set up to deliver large commercial buildings or highly specialised facilities like hospitals. But when it comes to creating high-performance, small-scale spaces to live or work in, our system is ideal.
Everything is designed with an architectural approach, so your tiny home will not only be well-built, but also carefully thought through in terms of layout, comfort and sustainability.
If you’d like to explore what’s possible, we’d be happy to talk through your ideas and show you how flexible our system can be.

‘Custom Build’ means having the chance to personalise your home without taking on the stress of a full self-build. Instead of managing the construction yourself, professionals handle the build while you make the key decisions about layout, finishes, and features.
Even with tiny homes, there’s a lot of scope for customisation. We can adapt the internal layout, add storage solutions, choose from different cladding and roof options, and include features such as solar panels, off-grid services, or compact wood-burning stoves. This way, your home can reflect your lifestyle while still being highly efficient and affordable.
At Wudl, we’ve always embraced the Custom Build model. Our modular, off-site building system is flexible enough to scale up, from one-off tiny homes, through micro and compact homes, to whole clusters of Custom Build housing for developers.
Custom Build has also been recognised nationally (including in the Bacon Review) as a key way to diversify the housing market and give people more choice. We’re excited to bring that same principle into the world of tiny homes, where even the smallest spaces can be uniquely yours.
sustainability
-
Passivhaus is the gold standard for energy-efficient building, and we can certainly achieve this with our more conventional homes. For tiny homes, however, it’s more challenging because of their compact size, the higher ratio of external walls to floor area, and the practical limitations on including some features like triple glazing, MVHR, or renewable energy systems.
That said, we use exactly the same high-performance materials and components across all of our buildings — natural insulation, airtight construction, and careful detailing — so our tiny homes are still built to a very similar standard. While they may not always reach full Passivhaus certification, they’re designed to be exceptionally warm, comfortable, and low-energy in use.
For a more detailed explanation about Passivhaus, please visit the BRE’s website.
-
Our tiny homes are designed to tread lightly on the planet. We build with natural, renewable materials such as FSC-certified timber, sheep’s wool, and wood fibre insulation — all of which help lower the carbon footprint while creating a healthier space to live in.
Every home is carefully detailed for energy efficiency. High levels of insulation, airtight construction and the option of renewable technologies (like solar panels, heat recovery ventilation, or efficient electric heating) mean our buildings are comfortable, low-cost to run, and well-suited to off-grid living.
Another important factor is longevity. Our homes are built to last for decades, not just a few years. Durable construction and relocatable design mean they can adapt to your needs over time, rather than ending up as waste.
And while our focus here is on tiny homes, the same sustainable system can also be used for slightly larger micro and compact homes, or even small clusters for community housing. That way, you can start small — and grow if your needs change.
technical & construction
-
Not exactly. While our homes are also built from pre-insulated panels manufactured off-site, we don’t use SIPs in the conventional sense.
Traditional SIPs typically sandwich rigid foam between two OSB boards. Instead, our panels are designed as a breathable, vapour-open system, using natural or recycled insulation such as wood fibre, hemp or sheep’s wool. This makes the home healthier to live in, with better moisture regulation, improved indoor air quality, and lower embodied carbon.
For a tiny home, these details really matter: in a small space, comfort, air quality and energy efficiency are even more noticeable day-to-day. Our approach gives you a warm, durable home with the lowest possible environmental impact — without compromising on strength or performance.
And while our focus here is on tiny homes, the same system is used across our micro and compact homes too, ensuring consistent quality no matter the scale.
-
Our homes are designed and built as permanent structures, just like conventional brick-and-block homes. Modern timber frame construction is a well-established method in the UK, and with proper maintenance, these buildings have the same life expectancy as traditional masonry homes — typically 60 years or more, and often far longer.
Timber frame structures have been used in the UK for centuries, with many examples lasting hundreds of years. Today’s engineered timber products, combined with modern design, protective finishes, and advanced construction techniques, make our buildings highly durable, energy-efficient, and robust.
In addition, all our homes are designed to meet or exceed current building regulations, and they can be adapted, extended, or refurbished in the same way as any other permanent home. With good maintenance, our homes will remain comfortable and durable for generations to come.
-
Most tiny homes fall outside traditional mortgage lending, especially those built on wheels or designed to remain fully relocatable. That said, we’re in the process of partnering with a finance provider who can offer funding options specifically for tiny homes, and we’ll be able to share more details soon.
For our more permanent models — such as the Micro Homes (flat roof) or Tiny Homes with pitched roofs, which are typically built on a fixed base rather than a chassis — mortgageability may be possible, as these align more closely with conventional housing standards. All of our buildings are designed with proven construction methods and durable, high-performance materials, which is a strong foundation for mortgage or finance approval.
-
All of our homes are designed and built to meet or exceed UK Building Regulations, which include strict fire safety standards. Even though they’re timber buildings, modern detailing ensures they’re safe and robust.
We use a combination of fire-resistant linings (such as fire-rated plasterboard), high levels of natural insulation, and integrated fire barriers to protect the structure. Timber itself actually performs well in a fire: rather than collapsing suddenly, it chars at a predictable rate. This charring forms a protective layer that helps maintain structural integrity for longer — often outperforming unprotected steel in real-world scenarios.
For tiny homes, we also pay special attention to compartmentation and safe escape routes, so even in a small footprint, you have secure options in the event of an emergency.
Every design is checked and approved in collaboration with building control and local authorities, ensuring full compliance with fire safety legislation.
And while this site focuses on tiny homes, the same fire-safe system is applied across our micro and compact homes, so you can be confident in the performance whatever the size.
-
Yes — for our Tiny Homes (including the Shelter, Tiny Tiny House, and standard Tiny House models), we usually build them in our factory and deliver them to site as a complete finished unit. This keeps the process fast, simple, and high-quality, with minimal disruption once on site.
For our slightly larger Micro Homes and pitched-roof Tiny Homes, we still manufacture the building system off-site — walls, floors, roof panels, and all the key components — but final assembly is often carried out on site by one of our trusted assembly contractors. This is usually under a fixed-price JCT contract, with the contractor handling foundations, ground works, lifting equipment, waste removal, and other site logistics.
Because we’ve assembled many homes ourselves in the past, we bring that hands-on experience into every project and work closely with contractors to make sure the build runs smoothly and to our shared quality standards.

costs & ordering
-
It’s one of the most common questions we get, but the truth is that costs vary depending on your choices and your site.
Some of the main factors include:
Size & specification: higher-end finishes, bespoke layouts, or extra features (like off-grid systems or renewables) will increase the price.
Site conditions: foundations, access, and services vary from plot to plot.
One-off vs multiple units: a single home will usually work out more expensive per unit than building several together.
As a guide:
Shell-only packages can start from the tens of thousands, depending on size and finish.
Fully fitted, turnkey tiny homes generally begin from around £20,000, with most projects (particularly micro homes) falling somewhere between £60,000 and £90,000 depending on specification and site.
Every home is still semi-bespoke, so we’ll work closely with you to refine the design, finishes, and features to match your budget. Once we understand your needs and location, we’ll provide a clear, fixed cost for the home, with site works and installation quoted separately.
-
We always aim to keep our pricing as accurate and up-to-date as possible, but like all construction projects, there can be fluctuations, especially with materials costs, which can change unexpectedly due to market conditions.
Once the full scope of your project has been determined, including the specific design, finishes, and any custom features… we’ll fix the cost of supplying the building itself. This means you can have confidence in the price of the main building package before you commit to proceed.
Please note that while we supply the entire building, we don’t assemble it on site. Instead, if needed, we can help you tender or negotiate with an assembly contractor. The costs for assembly, groundworks, and site-specific works are separate, and they may vary depending on factors like the contractor’s pricing, the site conditions, and any additional works required.
Fell free to give us a call if you would like to discuss this aspect further.
-
Yes, as with any building project, there are additional costs you should plan for beyond the cost of the building itself. Some are essential, while others help reduce risks or improve quality. If you’re spending upwards of £50,000, it’s crucial to ensure everything is done properly.
Here are some of the most common additional costs to consider:
Site/plot of land: Usually the largest single cost.
Site clearance and preparation: Removing existing structures or vegetation and levelling the site ready for foundations.
Planning application: Includes professional fees (drawings, forms, design statements) and Local Planning Authority fees. A simple application might cost around £1,000, but complications can increase this.
Topographical site survey: Needed for accurate dimensions, levels, trees, drainage, etc.
Site investigation: Phase 1 (desk study) assesses risks; Phase 2 (intrusive survey) confirms ground conditions; Phases 3–4 (if needed) cover contamination and remediation.
Party Wall Act notice: Required if the building is on or near a boundary.
Ground gas protection: If radon or methane is present, protective measures will be needed.
Foundations and below-ground services design: Site-specific work, even with modular buildings.
Utility connections: Vary by site and services; even off-grid solutions require water and waste disposal.
Site insurance: Mandatory for UK construction sites.
Building inspections: Approved Inspectors check compliance with Building Regulations.
Structural warranty: Often required by mortgage lenders; otherwise optional for peace of mind.
Energy performance calculations: Needed to show compliance with Building Regulations.
Passivhaus Certification (optional): Additional cost for achieving stringent low-energy standards.
Airtightness test: Required for Passivhaus and increasingly for Building Regulations compliance.
This isn’t an exhaustive list, and every project is unique, so it’s always best to seek tailored advice for your specific site and building.
If you’d like to discuss any of these costs, or how they tie into the pricing accuracy and fixed building supply costs we offer… please get in touch. We’re always happy to help.
-
Possibly, but it depends on the scale of the project. Right now, we’re not able to ship one-off individual tiny homes overseas, as the cost of transport and compliance checks would make them unrealistic.
For larger projects, usually five or more homes, exporting or even setting up local manufacturing partners becomes much more viable. In those cases, we can explore adapting our designs to meet local building codes, materials availability, and climate conditions while still maintaining our high standards of quality and performance.
We’re already in discussions about how best to make our homes available internationally, whether that’s through shipping modules, licensing our system, or working with partners abroad.
If you’re outside the UK and would like to explore a project with us, please get in touch. And for updates, you can also subscribe to our newsletter… we’ll share news as soon as more options become available.
-
The first step is simply to share a few details with us, things like your site location, access, and any planning history (if you know it), along with what kind of home you have in mind. Don’t worry if you’re still at an early stage, we can help shape the brief and advise you on the best next steps.
Useful starting points include a site plan, postcode, photos, or any planning documents, but we’re happy to work with whatever you have.
We don’t build to other people’s designs. Our tiny homes are based on a set of tried-and-tested configurations that allow for plenty of customisation, but they need to follow our architectural logic and off-site manufacturing approach. If you already have planning permission for a different design, we may still be able to help, sometimes through a minor amendment, sometimes by revising the application.
We’ve designed the process to be as simple and supportive as possible. From first enquiry through to feasibility, planning and delivery, we’ll guide you every step of the way.
If you’re unsure whether your project is the right fit, or how to get things moving, just drop us a message and we’ll take it from there.
time-scales
-
The build itself can be surprisingly quick — for the smallest homes, we can manufacture them as a complete unit in our factory (ready to deliver) or supply them as a flat-pack kit for rapid assembly on site. In both cases, the shell can often be completed within a week.
However, the overall timeline depends on more than just the build:
Planning: in many cases you’ll need planning permission, which can take several months depending on your local authority and whether changes are needed.
Made-to-order components: items such as doors and windows usually have lead times of 10–12 weeks, as they’re manufactured to fit your home.
Site preparation: groundwork, access, and services also add to the programme.
Once everything is in place, on-site assembly is fast… our homes are designed for efficient delivery and installation, and we work closely with contractors to make sure the process is smooth.
If you have a site or timeline in mind, it’s always best to get in touch as early as possible. That way, we can help you plan a realistic route forward and avoid unnecessary delays.
