As long as your summer house shed is no higher than a 4m with a dual pitched roof (with an eaves height of no more than 2.5m) and no larger than 50% of the size of your garden, you should be able to build without planning permission.


Make sure to double check with your local councill or read our guide to planning permission.

Most ‘sheddies’ will say that a shed has to have certain features like an apex roof and ample storage space. On the other hand, a summer house is more likely to be used for leisure activities rather than as storage or a workshop. It will arguably feature more windows and glazing to allow natural light and may even be hooked up with utilities. However, with our BillyOh Penton summerhouse with side shed, you can have the best of both worlds!

We offer a range of BillyOh summerhouse sheds with customisable sizes and features to suit all buyers. For example, our 4 x 8 summerhouses start from just £879.

A summer house offers a whole host of potential uses, varying from the common and conventional to the decidedly outside of the box. If you’re looking for summer house ideas, you could use it for:

  • Garden storage if you go for a summer house with shed 
  • A workshop or tool shed 
  • A room for relaxation
  • Outdoor dining
  • A garden office
  • A home gym

With even a small summer house, the possibilities are endless.

Generally, garden buildings such as summer houses are classed as ‘permitted developments’, meaning you wouldn't need planning permission. This is as long as your summer house shed isn’t:

  • Built further forward than the front of your house
  • Higher than one storey
  • Higher than a max height of 2.5m at the eaves
  • Larger than 50% of the area of your garden

Despite this, we’d strongly recommend contacting your local planning authority to discuss this. The larger your garden building and the closer it is to your property boundary, the greater the likelihood that permission for a summer house will be required.


For more information, read this guide on planning permission.

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.

If you’re not careful, condensation can rapidly build up in your garden summer house structure as a consequence of changing temperatures throughout the year. But with proper care and maintenance, you can stop damp in your summer house.

Make sure there is sufficient airflow through your summerhouse and be sure to aerate it even in the winter months. Leaving the doors and windows open will allow your garden building to breathe. To restrict the ability of moisture to penetrate the timber, and stop rot and mould:

  • Don’t store damp items in your summer house
  • Opt for pressure-treated timber or treat your summer house with wood treatment
  • Think about installing a vapour membrane if need be
  • Build your garden summer house on a raised base with no direct ground contact

Our range of BillyOh summerhouses are all designed to be easy and simple to assemble. Using the digital assembly instructions included in your order confirmation and with a team of at least 2 people, the handy pre assembled panels mean you will have your BillyOh building up in no time! You’ll just require some basic tools like a drill and bits, level, and hammer.

Our tongue and groove panelling provides a weather-resistance, tight interlocking seal to keep your warm in winter and cool in summer. However, to further insulate your summer house, you could consider:

  • Using a draught excluder
  • Installing a vapour barrier 
  • Installing floor ad roofing Celotex insulation sheets
  • Upgrading to double-glazed windows


This can be especially useful if you plan to use your summerhouse as a home office throughout the year or overnight. For more, read our guide to damp-proofing and insulating a garden building.
