Tree Houses in Lewes, East Sussex (42)

Not always. It's well worth contacting your local planning authority to discuss your ideas before starting on your project.

How long does it take to build a treehouse?

This comes down to how elaborate and complex you want the treehouse to be. A basic square treehouse for your kids will usually take less than a week to build. However, if you plan to add multiple platforms with bridges it could take over a month to complete. Elaborate treehouses that are designed for adults may take months to finish.

How long do treehouses last for?

This depends on how well the treehouse was built and the materials used. Most professional treehouses are designed to last well over 10 years.

As we mentioned previously, hiring a professional treehouse builder is the best way of guaranteeing your treehouse is safe and secure. Having said that, it’s possible to build a treehouse yourself providing you have the necessary skills.

Below, we’ve summarised how to build a treehouse:

1. Pick a strong tree with stable, wide branches.

2. Plan how you want your treehouse to look and its dimensions.

3. Buy the necessary tools and materials.

4. Build your supports for the base of your treehouse.

5. Fit braces to hold up your treehouse.

6. Add the flooring so your treehouse has a platform.

7. Add walls and railings.

8. Install an entrance.

9. Add a ladder so you can reach the treehouse.

10. Finally, install a roof.

There’s a vast difference between a simple child's treehouse and a lavish guest treehouse. This means the price you pay for a treehouse will vary from project to project. There are a few key factors that’ll affect the cost to build a treehouse including:

• Size: The larger your treehouse, the more it’ll cost to build.

• Materials: Using high quality materials will make sure your treehouse lasts for years but it will be more costly in the first place.

• Design: If you plan to build a complex treehouse, this will be more expensive than a basic play room.

• Furnishings: Adding furnishings and furniture will also push up the cost for your project.

• Location: Labour costs vary throughout the UK.

Cost to build a treehouse

So, how much does a treehouse cost? Bearing the above factors in mind, the average price of a basic kids treehouse is £8,000. However, if you’re planning to install a custom, luxurious treehouse, you can expect to pay between £5,000 and £80,000.
