A 12 x 8 summerhouse is a great choice for those with slightly larger gardens or decks who want to make the most of their space. Below, we’ve listed just some of our favourite and most popular 12 x 8 summerhouse across a range of styles:


1. BillyOh Bella Tongue and Groove Pent Summerhouse


The long and plentiful windows that wrap around the front gives the Bella an ultra-modern and stylish look. Whilst the adaptable door placement means you have the ultimate say in how the summerhouse looks in your garden.


2. BillyOh Petra Tongue and Groove Reverse Apex Summerhouse


The Petra summerhouse is a great companion during the summer months and provides a cosy relaxing space throughout the rest of the year. The large windows and optional door placement allows you to get as much natural light as possible, great for entertaining.


3. BillyOh Harper Tongue and Groove Apex Summerhouse


The Harper Summerhouse is designed with tongue and groove panels, with a Georgian bar window giving it a traditional look. The Apex design allows for increased headroom inside of the summerhouse, making mobility extremely easy. Available in a range of different sizes, the Harper can fit in all types of garden styles and sizes.


4. BillyOh Sasha Log Cabin Summerhouse


The Sasha is a modern single room building with large opening windows giving a bright, airy interior to relax in the comfort of your own garden.

Even a 12 x 8 summer house shouldn’t require planning permission, unless:


  • You intend to use it as a permanent residence
  • It’s larger than 50% of your garden
  • It’s built past the front wall of your house
  • Its eaves are higher than 2.5m
  • It’s dual-pitched roof is higher than 4m (or 3m for any other roof)


If your 12 x 8 summer house meets those requirements (all our BillyOh summer houses are built to allow for these specs), then it should fall under ‘permitted development’. However, these rules may vary slightly depending on where you live. So be sure to talk to your local council or check out our guide to planning permission.

At Garden Buildings Direct, our summerhouses are made using high-quality materials and construction methods. We’re so confident in our 12 x 8 summerhouses that we can offer our BillyOh 10-year guarantee against rot, decay, and insect infestation. Our Bella Pent 12 x 8 summerhouse, for example, features a lovely modern pent roof style without a tall pitched apex roof and had wide-opening double doors to allow for maximum sunlight.

Our BillyOh summerhouses come with fast and free delivery to most of the UK mainland. Provided with your 12 x 8 summerhouse will be assembly instructions that, with a friend and some basic tools, you can follow to have your summerhouse up in no time!
