Check your proposed summer house against the conditions below to see if you’ll need planning permission.


  • Taller than 4m at the highest point for a dual-pitched roof? Yes.
  • Eaves higher than 2.5m? Yes.
  • Built past the face of the front wall of your property? Yes.
  • Larger than 50% of your property’s garden? Yes.
  • Higher than one storey? Yes.

Otherwise, your summerhouse should fall under ‘permitted development’. These rules may vary depending on where you live, however, so it’s always wise to check with your local council if you’re in any doubt. If not, you can always read more over at our guide to planning permission.



This all depends on what you intend to use it for. As most summerhouses are single-room structures, they naturally lend themselves to socialising. At Garden Buildings Direct, though, we’re aware that not everyone has the same space and budget to work with, that’s why we offer 4 x 8 summerhouses all the way up to our larger 16 x 10 models.


But if you’re planning to have multiple people around to entertain them for coffee and cake, think about what furniture you can fit in. Another option would be to consider placing your summer house on a deck to maximise on the open plan space. Either way, a 16 x 10 summerhouse offers more than enough space for furniture and tables.



A structurally sound base is essential in ensuring your summer house can last as long as possible. Your summer house base should be flat and level, so as to avoid cracking and breaking the timber or putting undue stress on window and door frames which could shatter glass. Your choices vary from a concrete base for your summer house to an ecobase or timber sub-floor. That’s why we offer many of these as add-ons upon purchasing your summer house.
