How Much Is Building a Tree House?
The average cost of building a tree house in the UK will typically fall between £2,000 and £8,000 for a professionally built structure. Simpler designs could cost less, and larger custom builds could cost more.
The price of a tree house will depend a lot on the complexity of the project. If you are just looking for a small wooden platform with a ladder, this will be much cheaper than a fully enclosed tree house with a roof, windows, and safety railings.
A small structure designed as a play platform will be much cheaper to install than a large enclosed tree house designed to function as a garden retreat.
Tree House Building Prices
Below is a table showing the typical tree house cost ranges based on the size and complexity of the structure:
| Type of Tree House | Average Price Range | Estimated Time |
|---|---|---|
| Basic tree house platform | £500–£1,500 | 1 to 2 days |
| Small tree house with railings and a ladder | £1,400–£2,500 | 2 to 4 days |
| Medium enclosed tree house | £2,500–£5,000 | 4 to 7 days |
| Large custom-built tree house | £4,500–£10,000+ | 1 to 2 weeks |
| Average tree house with slides or rope bridges | £3,000–£8,000 | 3 to 7 days |

Bespoke, large-scale, and habitable tree houses, especially the plush luxury ones designed to sleep a lot of guests, can cost anywhere from £15,000 upwards to over £100,000.
The cost of a tree house can easily creep up when you add in extras. For instance, building a slide or a top-level bridge into the design requires extra work and materials to ensure it's structurally sound.
If the tree house needs to be propped up with ground supports or posts rather than just relying on the tree itself, that's going to push the price up even further because you're looking at more hours of labour and more materials to get the job done that way.
Labour Costs and Timescales
Labour costs can make up a large proportion of the cost of building a tree house. This is especially true when it comes to custom designs.
Labour costs will vary depending on the size and complexity of the tree house, as well as how easy the site is to access.
| Type of Project | Estimated Timescale | Typical Labour Cost |
|---|---|---|
| Basic tree house platform | 1 to 2 days | £200–£600 |
| Small tree house with railings and ladder | 2 to 4 days | £400–£1,200 |
| Medium enclosed tree house | 4 to 7 days | £800–£2,100 |
| Large custom-built tree house | 1 to 2 weeks | £2,000–£4,200 |

Building in remote locations can increase costs due to difficult access and transportation of materials. Small tree houses may take just a couple of days to install. However, larger structures may take several weeks.
If scaffolding or safety equipment is needed for taller tree houses, the labour costs may increase, and this could also add some additional time to the job.
Your location in the UK can also affect how much you can expect to pay for the labour side of things. Those based in and around London can expect to pay higher labour costs than those based in the North or other parts of the UK.
Supply Costs
The main materials used when building a tree house can make up a big proportion of the total tree house cost. The quality of the materials that you choose will affect both the durability and the overall budget for the project.
Typical tree house supplies include:
| Supply | Average Cost |
|---|---|
| Timber framing | £150–£600 |
| Decking boards | £100–£400 |
| Structural fixings and brackets | £50–£200 |
| Safety railings | £80–£300 |
| Ladders or staircases | £80–£350 |
| Roofing materials | £100–£400 |
| Screws, bolts and anchors | £30–£100 |
| Protective wood treatment | £20–£80 |

Treated timber normally comes in at around £300 all the way up to £500 per cubic metre, whereas cedar cladding can set you back anywhere from £600 to £1,000 per cubic metre. The materials themselves usually make up between 40% and 60% of the overall cost of a tree house.
You'll most often see pressure-treated wood being used for the support structure and deck of a tree house. It provides a solid enough base to work from.
To build something that's going to last and stay safe, you should be using galvanised screws and nails as a minimum. Properly building a solid floor and decking is a must because you've got to allow for tree movement and to withstand the elements. All that weather will try to wear it down if you don't do it properly.
If you go for higher quality materials, then this will put the price up, but on the other hand, the better stuff will last longer, and the chances are you'll be less likely to need repairs or have to swap out parts in the future.
Additional Costs
In addition to the essential supplies and labour costs, there are also some additional features that may increase the total cost of a tree house beyond the basic structure.
For example, you may choose to include a slide, climbing wall, or rope bridge to make your tree house more fun and extravagant. You may also wish to add windows, doors, and insulation for functionality and comfort.
Some tree house projects may also include extra features or finishing work, such as:
| Additional Feature | Average Cost |
|---|---|
| Slides or climbing walls | £100–£500 |
| Rope bridges | £200–£700 |
| Windows and doors | £150–£600 |
| Insulation or internal finishes | £200–£800 |
| Decorative features | £100–£400 |
| Garden landscaping | £150–£1,000 |
| Waste removal | £50–£200 |

Tree houses designed for children often include features such as slides, climbing walls and pulleys.
Prices for extras like all the above are going to vary greatly depending on how complicated your project is and on the kinds of materials you decide to use.
Cost Factors for Tree House Building
Several factors can affect the overall cost of building a tree house, including:
Size and Design
If you want a much larger tree house, this will require more timber and labour, so it will ultimately end up costing more than a smaller tree house. Also, if you are looking for a custom or more intricate design, this can increase the time and cost of the job.
Height of the Tree House
Higher installations will require additional safety precautions and materials. It may also be more difficult to access, which can increase the time it takes to build, and the additional features needed will increase the cost.
Strength of the Tree
The tree that supports the tree house must be strong enough to handle its weight. If not, you may need to invest in some additional posts for support.
Materials Used
Premium timber or weatherproof materials will increase the overall price. Also, any decorations or other elements added will increase the cost, especially if you are choosing premium products.
Accessibility
If your garden or the tree in question is difficult to access, this may make it more difficult to transport materials and equipment to the job site.
Additional Features
If you want to add any additional features to your tree house, this can also affect the overall cost quite significantly. Things like slides, bridges, and decorative elements can all add to the cost of the job.
Labour Rates
Labour costs can vary depending on the contractor that you choose, their experience and your location in the UK. Those based in and around London can expect to pay more for the labour costs than those based in the North or other parts of the UK.
Types of Tree House
There are several different types of tree houses to choose from. Below is a list of common tree house types so that you can get a better idea of which type of tree house may be best for you and your garden space:
Platform Tree House
A platform tree house is a simple raised wooden platform supported by a tree or posts. This is usually the most budget-friendly option.
Pros
- ✔ Cheap and quick to install.
- ✔ Requires fewer materials.
- ✔ Ideal for small gardens.
Cons
- ✖ Limited weather protection.
- ✖ Less secure than enclosed structures.
A simple platform tree house will usually cost around £500 to £1,500.
Enclosed Tree House
An enclosed tree house is a more complex structure with walls, windows and roofing, offering better weather protection.
Pros
- ✔ Better weather protection
- ✔ More comfortable for children
- ✔ Greater durability
Cons
- ✖ Higher tree house cost.
- ✖ Longer installation time.
An enclosed tree house will usually cost around £2,000 to £5,000.
Multi-Level Tree House
A multi-level tree house is a larger design with multiple platforms or levels connected by ladders or bridges.
Pros
- ✔ Exciting design for children.
- ✔ Large play area.
Cons
- ✖ Complex installation
- ✖ Higher price point
A multi-level tree house will usually cost around £4,000 to £8,000 or sometimes even more, depending on how extravagant the design is.
Custom Tree Houses
Custom tree houses are professionally designed structures that may include slides, rope bridges, balconies, or themed designs.
Pros
- ✔ Fully personalised design
- ✔ High-quality finish
Cons
- ✖ Expensive
- ✖ Requires specialist builders
A custom tree house cost can vary. Usually, you can expect to pay around £5,000 to £10,000+ for a custom design. The more customised it is, the more it is likely to cost, so this is something to keep in mind if you want something specific.
Alternative Garden Structures
If a tree house isn't suitable for your garden or budget, there are several alternative outdoor structures that can offer similar benefits. Each of these has different costs, installation requirements and levels of maintenance.
Below is a list of the most popular alternative garden structures that you may wish to consider instead of a tree house:
Playhouse
Playhouses are one of the closest alternatives to a tree house, particularly for families with young children. Because they sit at ground level, they are generally easier and cheaper to install. Most playhouses cost between £300 and £2,000, depending on their size and materials.
Pros
- ✔ Usually cheaper than a tree house.
- ✔ Easier and safer to access.
- ✔ Many models can be installed as a DIY project.
Cons
- ✖ Doesn't offer the same elevated experience as a tree house.
- ✖ Requires a suitable base.
- ✖ Timber models still need ongoing maintenance.
Garden Shed
A garden shed is another practical alternative. These are mainly used for storage but can sometimes be adapted into workspaces. Prices typically range from £500 to £3,000 depending on size and material. This means they are a similar or slightly lower price than the average cost of a tree house. You'll need a solid base to install a shed.
Pros
- ✔ Useful for storage or workshop space.
- ✔ Often cheaper than a tree house.
- ✔ Available in timber, plastic and metal options.
Cons
- ✖ Requires a solid base.
- ✖ Less exciting for children than a tree house.
- ✖ Timber sheds need ongoing maintenance.
Garden Rooms
Garden rooms are a much more premium option and are significantly more expensive than most tree houses. The costs for these usually start from around £10,000 and can exceed £20,000 or more for bespoke or highly customised designs.
Pros
- ✔ Can be used all year round.
- ✔ Adds valuable living or working space.
- ✔ Generally low maintenance when built with quality materials.
Cons
- ✖ Much more expensive than a tree house.
- ✖ Usually requires professional installation.
- ✖ May require electrical work and foundations.
Raised Decking Platforms
Garden decking is a much simpler alternative to tree houses that can still create a nice elevated outdoor space. Prices usually start from around £800 and can increase depending on size and materials. Decking can sometimes be installed as a DIY project, but raised or larger platforms may require professional installation.
Pros
- ✔ Often cheaper than a tree house.
- ✔ Creates an elevated outdoor space.
- ✔ Can sometimes be installed as a DIY project.
Cons
- ✖ Less suitable for children's play.
- ✖ Timber decking needs regular maintenance.
- ✖ Large raised platforms may still require professional installation.
Pergola
Pergolas are mostly decorative structures, and they are used to create shaded areas in the garden. A typical pergola costs between £800 and £3,000. This means that they are similar in price to or slightly cheaper than a basic tree house. Installation is usually straightforward, especially when using pre-made kits, and many homeowners choose to install them themselves.
Pros
- ✔ Creates a shaded outdoor seating area.
- ✔ Usually straightforward to install.
- ✔ Lower maintenance than many timber structures.
Cons
- ✖ Not suitable for climbing or play.
- ✖ Doesn't provide enclosed shelter.
- ✖ Mainly decorative rather than functional.

Building Regulations for Tree Houses
Building regulations don't apply to most tree houses in England and Wales (Scotland and Northern Ireland have their own regulations) as long as they are either:
- 15m² or less with no sleeping accommodation.
- 15 to 30m², single storey, with no sleeping accommodation, and either over 1 metre from a boundary or made primarily from non-combustible materials.
However, these exemptions don't apply if you are running a new circuit to the tree house. This is notifiable work that must either be notified to building control or carried out by an electrician registered with a competent person scheme who can self-certify.
Safety considerations are especially important for elevated structures. Builders must ensure that the tree house is stable and includes appropriate safety features such as railings and secure ladders.
Hiring Contractors Checklist for Tree House Builders
When you are hiring a professional to build your tree house for you, there are some things that you should consider. Below is a checklist to help you out when hiring a professional tree house builder:
- Get at least two or three written quotes — compare prices and what's included.
- Look for a builder with experience creating tree houses or other elevated garden structures — this helps ensure safe, structurally sound construction.
- Ask to see photos of previous projects — so you can assess quality and finish.
- Check that they have Public Liability Insurance — to protect you in case of damage or accidents.
- Find out how the tree house will be supported and whether the tree is suitable for the structure — to ensure it is safe and stable long term.
- Make sure the quote includes materials, waste removal and disposal — so you avoid unexpected extra costs.
- Check whether safety features such as railings, ladders and access platforms are included — for safe everyday use.
- Read customer reviews before making your final decision — to help confirm reliability and workmanship.
Removing or Replacing a Tree House
Over time, your tree house may need to be removed, replaced, or repaired due to ageing timber or changes to the supporting tree. If your tree house needs to be removed or replaced, you may be wondering about the costs involved with this type of work.
The cost to remove a tree house can depend on several factors, such as:
- The size of the structure.
- The height of the installation.
- The access to the garden.
- Waste removal requirements.
In general, you can typically expect to pay around £150 to £700+ for removing a tree house. As mentioned, the price may vary depending on certain factors.
If your tree house becomes unsafe, you may choose to fix structural issues or replace damaged timber rather than go ahead with removing the entire structure.
Replacing your old tree house with a newer, more modern design can significantly improve the safety and extend its lifespan.
FAQs
Can I Build a Tree House Myself?
It is possible to build a simple tree house yourself if you have good DIY skills and the right tools, and you can save around £400 to £2,100 in labour costs by doing so. However, larger or more complex tree houses are usually best left to a professional, particularly when working at height or attaching structures to a tree safely.
Do I Need Planning Permission for a Tree House?
Yes, you will usually need planning permission for a tree house, as it is required for a raised platform more than 0.3 metres above ground level, which tree houses generally are. These are England's rules, so check with your local authority if you live elsewhere in the UK, or if your tree house will be less than 0.3 metres above ground level. Be prepared to pay around £272 in England, £283 in Wales, or £371 in Scotland for the planning application, where needed.
How Long Does a Tree House Last?
A well-built tree house will last for many years if properly maintained. The lifespan will depend on the materials used, how the timber was treated, exposure to the weather, how well the structure is looked after, and the condition of the tree the tree house is built on. Regular inspections and occasional treatment can help keep it in good condition for longer.
Can a Tree House Damage the Tree?
Yes, if it's not built properly, a tree house can damage the tree. That's why it's important to choose a suitable tree and use the right fixings. Professional builders will usually use specialist supports that allow the tree to move and grow naturally.
How Long Does It Take to Build a Tree House?
A simple tree house platform can often be built in a couple of days, while larger or more complex designs may take several weeks. Features such as rope bridges, balconies and staircases can add to the build time, and bad weather may cause delays.
What Type of Tree Is Best for a Tree House?
Strong, mature trees like oak, beech, and sycamore are often used for tree houses. Ash trees are not usually recommended as they may show symptoms of ash dieback. The most important thing is that the tree is healthy and strong enough to support the structure safely. In some cases, extra support posts may also be needed.
