Types of Summer House
The classic garden house, created from timber and built for relaxation. A place for peace and quiet, a place to spend those long, sweltering summer days. A typical design maximises the amount of natural light that reaches the interior and keeps the separation between outdoors and in to a minimum. But when it comes to style and shape, our wide variety of buildings gives you the freedom to pick to your preference.
The heavy-duty cousin of a regular building, you’ll find log cabin summerhouses provide comfort that can be enjoyed throughout the year. While still providing a dedicated place to relax, and full of features that let you make the most of summer, the thicker log walls afford a more comfortable interior better suited for the colder months of the year and adding to the usability of your summerhouse.
In-built insulation expands what you can do with a summerhouse. It becomes so much more than a place to relax, with the ability to use the building as an office or studio space. With reduced heat transfer due to the insulate features - like insulation foil and double glazing - these insulated summerhouses aren’t just for summer, but can become a whole new room in your home.
Made for those awkward spaces and unused corners - add a place to relax and unwind. Specially designed for right-angle spaces, a corner summerhouse is the perfect way to start making the most of your garden by adding a place to relax. The design of these buildings is great for sunlight, with windows on two sides to help make the interior bright and airy.
FAQs
At ~96 sq ft, a 12x8 is a proper garden room for relaxing and entertaining — comfortably fitting a sofa and chairs, a dining or drinks table, or a garden bar, with room to host a small group. It could also make a good sheltered exercise room in the garden. It's one of the most popular sizes for a summerhouse that's more than just a seating spot.
Usually not. Size only matters via the 50% rule (all outbuildings under half your garden); otherwise it's about position (behind the front of the house) and height (2.5m within 2m of a boundary, 4m apex / 3m pent beyond that). Listed or conservation-area homes are the exception — see our planning guide.
At this size, double doors and dual-aspect windows work well — they open the room up for entertaining and widen the view. Choose front-and-side glazing if it'll sit in a corner, or wide front glazing if it looks straight down the garden.
What Size Garden Is Right For a 12 x 8 Summer House?
Choosing the right sized building for your garden is crucial if you plan to make the most out of it. If the building is too big it will dominate the garden and leave it feeling cramped, but if it’s too small it may leave you wishing you had chosen something larger. It’s also important to buy according to your needs, including how many people might be inside at one time (the more people, the bigger the building needed).
For a 12’x8’ foot or 8’x12’ garden summer house, the right-sized garden will provide enough space around the building for manoeuvrability. We recommend at least one foot on each side to reduce the chance surrounding structures or features could damage the building.
Planning regulations for summerhouses state that your building cannot take up more than 50% of your garden space - but in reality, we would not recommend taking up any more than 30% of the garden. Reducing your garden to any amount below 70% of its original size can often be a step too far and leave it feeling cramped.
With that in mind, the right size garden for a 12x8 building would be anything bigger than 320 square feet or 29 square metres - for example, a 14 x 24 foot garden would be ideal.

Customer Testimonials
Elodie's Picton Corner Summerhouse
It’s allowed us to spend so much more time outside no matter what the weather. We’ve even been out there in the winter with our coats and blankets on, it really is usable all year!
Stacey's Renna Summerhouse
The large windows and double doors provide an uninterrupted view of the garden and plenty of room inside to enjoy the view. My favourite thing - hands down, has to be the ability to sit and enjoy a space away from home.
Izzie's Holly Summerhouse
I just loved the design of the BillyOh Holly summerhouse from the outside and I wanted something that was the same width and length to fit perfectly into the corner of my garden.
Emma's Bella Summerhouse
It’s allowed us to have a space away from the house to enjoy with friends so we don't wake the kids up! Also, over the last year it’s allowed us to feel like we are sort of going out, even if it is just to the bottom of the garden!
Farayi's Penton Summerhouse
We chose this building for storage and somewhere to sit and enjoy the garden. We now have a solution for both which is just amazing. It’s really allowed us to sit and admire the view and still be in the garden all year round.
Lisa's Tessa Summerhouse
It had more windows than everything else, and the dual aspect doors made for a flexible space. We chose Garden Buildings Direct because of the good value and a good selection of summerhouses.
