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.

Utility is guaranteed with a summerhouse shed that serves two functions in one. Unlock both a relaxing garden experience and a practical outdoor storage unit in one convenient building.

The side store is included with:
Penton Corner Summerhouse
BillyOh Tianna Log Cabin Summerhouse with Side Store

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


Our BillyOh 16 x 8 summerhouses offer a premium in not only space, but style, and construction. Like all our summerhouses, a 16 x 8 summer house is built with high-quality materials with longevity in mind. And if you want to see what that looks like, we’ve come up with a couple of our most popular 16 x 8 summerhouses to give you an idea:


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.


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.



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.

For more on how to damp proof and insulate your wooden summer house, check out our comprehensive guide.



The size summerhouse that you’ll be allowed to build without planning permission will rely on a few rules but also be relative to your house size. For example, if your summer house is:


  • Not being used as a permanent residence.
  • No larger than 50% of your garden.
  • Not built past the front wall of your house.
  • No higher than 2.5m at the eaves.
  • No higher than 4m at the highest point (for a dual-pitched roof).

Then it should fall under ‘permitted development’ and therefore, not require planning permission. Our 16 x 8 summerhouses are built with these heights in mind. 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.



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 haven’t applied for planning permission to make your summer house a permanent residence then it is unlikely you will legally be allowed to live in it permanently. However, a 16 x 8 summer house offers excellent opportunities to allow guests to occasionally stay without having to break the bank applying for planning permission and building an extension.

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
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.
