Cost of Building a Summer House
Summer house installation guide and pricing
Garden design is hugely popular in the UK thanks to various garden renovation TV programs. This, along with the rise of diy stores and garden centres selling a huge range of innovative products, has led to many people beginning to see their gardens as extensions of their homes and wanting to put them to good use for both relaxation and entertaining. Adding a summerhouse adds another dimension to the garden and can provide children with a little adventure.
Garden outbuildings can vary significantly in their style, size and specification. With many summer houses, you can build without the need for hiring a local tradesman. But almost all of these buildings, even simple prefabricated units, require at least two fit people for the installation.

Things to consider with summer houses
When it comes to buying a summer house the price depends on the size of the building, whether a modular or bespoke design, the building materials used, plus the cost of the finishes, fixtures and accessories you choose. Another cost consideration is whether planning permission is required. The location, size, height and intended use of your summer house will determine whether planning is required or not.
But if planning consent is required, then your neighbours will be given the opportunity to raise objections and the process will cost a few hundred pounds extra at least. But in most cases, summer houses will fall under the permitted development rules which means as long as the new building is no more than 2.5 metres high, does not take up more than half of the area of the main building and is not within two metres of your neighbours boundary – then planning consent is not required.
However, if you plan to use the summer house as accommodation with a bedroom, bathroom or kitchen – then this is a change of use and planning consent will definitely be required. But gyms, playrooms, home office and pools or spas are all considered incidental so no problems with planning.
Doing it Yourself
A DIY build for a small and basic summer house, particularly a prefabricated version, is definitely possible for the average DIY enthusiast. No specialist tools or equipment are needed, just basic, everyday tools plus a helping hand or two! The foundation is probably the only really difficult part which may require some experience outwith standard home DIY projects. But a decent concrete foundation is required for durability so it may make sense to get someone else in to do the concrete foundations, then you can easily tackle the rest yourself as a DIY project.
If doing the foundation yourself be very careful you do not rupture a water/gas main or dig up electricity cables! This can be a very costly and dangerous mistake! Most of the problems people have with outbuildings are caused simply by trying to cut costs and corners. But if you always use a proper foundation, then carefully erect the structure according to the manufacturers’ instructions and have the summer house treated regularly to avoid damp and rot problems (if timber) – then major problems are unlikely.
