These are some of the bespoke treehouses and playhouses I have built. Often a customer bases their structure on one I've done previously, which is why some of them have a similar style. There are also ones that are totally unique. They can be made to fit in with pre-existing buildings in your garden, or to echo the style of your home. Ultimately, they can be whatever you want them to be. The designing is one of the fun parts of the job.
