Types of Summerhouse

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 ~120 sq ft it's a generous garden room — comfortably seating six to eight with sofas and a table, and room to move around. It's well suited to entertaining, a family garden lounge, a games or hobby room, or simply a spacious place to relax and enjoy the garden.

A solid, fully level base across the whole footprint — at this size a concrete slab or well-laid paved base is the reliable choice. Keeping it level and free-draining holds the larger structure square and the doors working, with the floor on its pressure-treated bearers.

A standard summerhouse is a warm-season space — lovely from spring to autumn, but the un-insulated walls and single glazing won't keep it cosy through winter. If you'd like to relax in it year-round, choose one of our insulated summerhouses, which are lined, insulated and double-glazed from the start; we don't recommend retrofitting your own insulation, as it voids the guarantee.

Can a 12 x 10 Summerhouse Be Too Big?

Like the rest of our large summerhouses, these sizes aren’t intended for gardens where space is limited. If you have a small garden - or even one where a 12’x10’ sized building would take up more than 30% of the existing space - this size may be too large. 

Adding a summerhouse to your garden can help you make the most of the space, but if the building is too big for the surroundings it can leave your garden feeling cramped - which may make it feel less inviting overall.

Customer Testimonials

Elodie's Picton Corner Summerhouse
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
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
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
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
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.
