In this guide, we’ll break down typical tree house building costs, the main factors that affect the price, and what to expect when hiring a professional.

How Much is Building a Tree House?

The average cost of building a tree house in the UK will typically fall between £2000 and £8000 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.

There are several key factors that could influence the final cost of a tree house, including the following:

• The size of the tree house
• The complexity of the design
• The materials used for the structure
• The height and location of the installation
• The number and types of trees that are used for support
• Labour rates for contractors on the job

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.

Labour prices may vary depending on the contractor. Some professionals will offer a fixed tree house builder cost for the entire project, whereas others may charge daily labour rates. A typical carpenter or builder may charge around £150-£300 per day, depending on their experience and location.

Tree House Building Prices

Below is a table showing the typical tree house cost ranges based on the size and complexity of the structure:

The average cost of a tree house can increase significantly if extra features are added. For example, installing a slide or a top bridge requires additional structural support and more materials.

If the tree house requires ground supports or posts rather than relying solely on the tree, the cost of building a tree house may increase further due to the extra labour and materials needed.

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.

Below is a list of the typical materials that you will need for building a tree house, along with the average costs for these different types of materials.

• 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

If you choose higher-quality materials, this will increase the price of the supplies. However, higher-quality materials will last longer and will reduce the likelihood of needing repairs or having to replace components 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.

Below is a list of the additional costs that may be involved with building a tree house and the prices that you may need to budget for these jobs:

• 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 around the tree house - £150 - £1000
• Waste removal after construction - £50 - £200

The prices for the above additional features can vary significantly depending on the complexity of the job and the types of materials that you choose.

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.

A professional carpenter or garden builder will typically charge around £200 - £300 per day.

The labour costs can differ depending on several factors, including the following:

• Size of the tree house
• Complexity of the design
• Height of the build
• The number of workers required
• Accessibility of the garden

Small tree houses may take just a couple of days to install; however, larger structures could take several weeks to install.

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.

More complex builds may require specialist carpentry skills to ensure the structure is safe and properly secured. For example, custom-built tree houses that include stairs, rope bridges or multiple levels will often require more experienced tradespeople.

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 more for the labour costs than those based in the North or other parts of the UK.

Cost Factors for Tree House Building

There are several different factors that could influence the overall tree house builder cost. Take a look at the list below for a better idea of what factors could affect the overall cost of the job:

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.

Building Regulations for Tree Houses

In most cases, you won’t need to worry about planning permission when it comes to tree houses if they are considered as small garden structures. Most will be covered under permitted development. However, you will need planning permission for your tree house if the work falls under the following criteria:

• It covers more than half of the garden
• It is over 4 meters tall
• It is located near a listed building or conservation area
• It is being used for a business, e.g. a glamping site or some other tourism site

You may also need to get planning permission if the tree house significantly overlooks any neighbouring properties, includes any sleeping accommodation, or is intended for frequent use rather than just occasional recreation.

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.

If the structure is particularly large or includes electrical installations, additional regulations may apply.

In any case, it is always best to reach out to your local authority before any work starts to make sure your design doesn’t require planning permission and to make sure it adheres to all building regulations.

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 - £1500.

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 £2000 - £5000.

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 £4000 - £8000 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 £5000 - £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 if you are a family with young children. These are built on the ground, so they are safer and easier to install than tree houses. In terms of price, they are usually a cheaper option, with costs starting from around £300 and reaching up to £2,000 for larger wooden designs.

Playhouses are often supplied as kits, so they can often be installed as a DIY project, but they need to be built on a flat base, such as paving slabs. The maintenance for a playhouse is pretty straightforward; a timber playhouse will need some occasional treatments to prevent it from any weather damage. Compared to a tree house, playhouses are easier to access if you need to fix or repair any parts.

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.

Smaller sheds can be installed without any professional help; larger ones may require some assistance. The maintenance varies depending on the material. Wooden sheds will need regular treatments, but plastic or metal options don’t require as much upkeep.

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.

The installation process for garden rooms is more complex and will usually require some professional help. This is because it often involves foundations, insulation and electrical work. However, garden rooms are great because they provide a fully usable space all year round. The maintenance for a garden room is relatively low if you use high-quality materials, although timber cladding may still need occasional treatment.

Raised Decking Platforms

Raised decking platforms are 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.

Timber decking needs regular cleaning and sealing to protect it from the weather, whereas composite decking offers a much lower-maintenance option. This is often cheaper than many tree houses, but decking is usually more suited to seating or entertaining rather than as a place where children can play.

Pergola

Pergolas are mostly decorative structures, and they are used to create shaded areas in the garden. They generally cost 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.

The maintenance on a pergola is minimal, particularly for metal designs, although wooden pergolas may need occasional treatment. Unlike tree houses, pergolas are not designed for climbing or play, so they serve a different purpose. However, they do provide a nice shaded area in the garden to shade children from the sun.

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 multiple quotes from local tradespeople
• Check their experience with carpentry or garden structures
• Ask for previous examples of tree house projects
• Confirm insurance and safety procedures
• Ensure materials used are suitable for outdoor structures
• Agree on the total price before work begins
• Confirm whether waste removal is included
• Check reviews and ratings from previous customers

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 - £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.
