Reasons to Choose Each Summer House Range
Choose Diamond if Value Is the Priority
Diamond summer houses are a good choice for customers who primarily want somewhere attractive to sit, relax, entertain or enjoy their garden. They provide a practical combination of traditional summerhouse appeal, useful garden space and value for money, making them ideal when you do not require the additional specification of the Platinum or Royal ranges.
Choose Platinum for Greater Flexibility
Platinum summer houses make sense when your garden building needs to do more than a conventional summerhouse. With higher specifications and insulation available on many models, they can be particularly suitable for home offices, studios, hobby rooms, and customers who want to use their building comfortably for more of the year.
Choose Royal for a Premium Year-Round Room
Royal summer houses are the premium choice when you are looking for something closer to an additional room rather than simply a summer retreat. Their fully insulated construction makes them particularly attractive for garden offices, studios, entertaining spaces and other uses where greater year-round comfort is important.
A Simple Way to Choose
Diamond = great-value summerhouse • Platinum = more comfort and versatility • Royal = premium year-round garden room.

More Information In Our Help Articles and Blogs
If you are still deciding which summer house is right for your garden, our help articles cover many of the questions customers ask before and after buying. From choosing the right style and understanding costs to planning permission, foundations, insulation, heating and condensation, these practical guides can help you make a more informed decision. You will also find advice on looking after your building and ideas for making your new summer house comfortable, attractive, and suitable for how you intend to use it.
How To Choose a Summerhouse Shed
Choosing a summerhouse shed involves thinking about much more than its appearance. The right building should provide enough space for how you intend to use it while also fitting comfortably into your garden. You may need to consider its size, position, construction, windows, doors and overall specification. Our guide explains key points to consider before you decide and can help you narrow down the many styles and options available. Read our guide to choosing a summerhouse shed.
Best Summerhouse Guide
With so many sizes, styles and specifications available, deciding which summerhouse is best for your needs can initially seem difficult. Your ideal choice will depend on your garden, available space, budget and what you want to do inside the building. Whether you are creating a space to relax, entertain, enjoy hobbies, or work from home, our summerhouse guide explains the key considerations that can help you compare options and choose a building that suits you and your garden. Read our best summerhouse guide.
How Much Does a Summer House Cost in the UK?
The cost of a summer house can vary considerably depending on its size, construction, specification and the features you choose. A straightforward garden retreat will naturally have different requirements from a larger insulated building intended for regular use throughout the year. It is also sensible to consider associated costs when planning your budget. Our detailed guide looks at summer house prices in the UK and explains some of the factors that can influence how much you should expect to spend. Find out how much a summer house costs.
Planning Permission Guide
Before installing a summer house, it is important to establish whether your proposed building is likely to require planning permission. Many garden buildings can be installed under permitted development rights, but restrictions and circumstances may apply. Factors such as the building's position, overall dimensions, and intended use can be relevant. Our planning permission guide provides useful information to help you understand the rules and identify when you may need to seek further advice before proceeding with your project. Read our summerhouse planning permission guide.
Heating Your Summerhouse Ideas
A little additional warmth can make your summerhouse considerably more comfortable during cooler weather and help extend the amount of time you can enjoy it throughout the year. The best heating solution depends on the size and construction of your building, whether it is insulated, how often you use it, and whether electricity is available. Our guide explores different ways to heat a summerhouse and highlights practical considerations when creating a warmer, more comfortable garden retreat. Explore ideas for heating your summerhouse.
Are Summer Houses Worth It?
A summer house can provide valuable additional space without changing the main structure of your home, but whether one is worthwhile depends on what you expect from your garden building. For some people, it provides a peaceful place to relax, while others use it as an office, hobby space, entertaining area, or multipurpose garden room. Our guide considers the practical advantages of owning a summer house and the points worth thinking about when deciding whether investing in one is the right choice for your household. Discover whether a summer house is worth it.
How To Build the Foundations and Base
A suitable base is one of the most important preparations when installing a new summer house. The base needs to provide a firm, level and stable surface capable of supporting the building correctly over the long term. Poor preparation can cause problems with doors, windows, and the overall structure once the building is installed. Our foundation guide explains different summerhouse base options and provides useful information to consider when preparing your garden before your new building is delivered and installed. Read our guide to summerhouse bases and foundations.
How To Control Condensation
Condensation and excess moisture can affect garden buildings, particularly during colder or damp periods when differences between internal and external temperatures become greater. Good ventilation, sensible heating, and appropriate building maintenance can all help control moisture levels. Understanding why condensation develops makes it easier to take practical steps to reduce it and protect your summerhouse and its contents. Our guide explains common causes of condensation and offers helpful suggestions for maintaining a drier, more comfortable environment inside your building. Learn how to control condensation in your summerhouse.
How To Insulate Your Summer Building
Insulating a summerhouse can help create a more comfortable internal environment and may be particularly worthwhile if you plan to use the building beyond the warmer summer months. You can incorporate insulation into areas such as the walls, floor, and roof, although the best approach depends on your building's construction. Our insulation guide explains the principles involved, the areas you should consider and why insulation can make such a difference when creating a garden office, hobby room or year-round retreat. Read our guide to insulating a summerhouse.
Colourful Summer House Paint Ideas
The colour you choose for your summerhouse can completely change how the building looks within your garden. Traditional natural shades can help it blend into surrounding planting, while brighter colours can transform the building into an attractive focal point. You can also use contrasting colours on doors, windows and trim to create a more individual appearance. Our summerhouse paint guide explores different colour schemes and inspires you to choose a finish that complements your garden, personal style, and the character of your summer building. Explore colourful summerhouse paint ideas.

Constructed with high-quality materials, their summerhouses are designed to withstand the elements while maintaining a beautiful aesthetic. Additionally, the customisable features allow you to tailor the space to match your preferences and needs, making it a seamless addition to your garden.
With a strong focus on craftsmanship and customer satisfaction, 1st Choice ensures you’re in a product that elevates your outdoor living experience.
Choosing A 20ft x 12ft Summer House From 1st Choice Leisure
When choosing a summer building, you need to check the specifications to ensure it will have the strength to withstand the elements. So always check the thickness of the timber, whether it’s made from redwood or the cheap, inferior whitewood, and how thick the framing is, etc.
Consider how the joinery-made doors and windows enhance both style and security, offering long-lasting beauty and peace of mind. Imagine the confidence in knowing that toughened glass provides an added layer of safety for both your loved ones and belongings. In contrast, imperfect horticultural glass, plastic, or perspex may not offer the same level of durability and protection. As you make your choice, think about the reassurance and elegance that quality materials bring to your space.
Free Installation Included As Standard On All Diamond & Platinum Buildings.
On many of the buildings available on the web, you will find that they will deliver them to your house and leave them for you to build. You can save a little money this way, but you must assemble it yourself. That’s OK if you are a good DIYer, but it will still be hard work.
The best option is to take advantage of 1st Choice’s FREE assembly option on the Diamond and Platinum buildings. They will do all the hard work – all you need to do is build a level base for it to go onto. And they can arrange that for you if you wish.
This way, you can be sure your new building will be built correctly, and all you need to do is enjoy it.
Insulating My Summer Building
To make the most of your new 20×12 building, it’s a good idea to have it lined and insulated for year-round use. Insulation can reduce heat loss by up to 60%, which means your building will stay cooler in summer and warmer in winter. It’s possible to do this yourself if you feel confident.
While there is an option to have this done professionally for you on all the Platinum buildings, it is actually a smart investment. Insulation not only enhances comfort on those hot summer days or cold winter nights, but it also offers long-term savings by reducing future heating costs.
Just contact us, and we will arrange a free quote for you.
This 20×12 Summerhouse Can Be Bespokely Made Just For You

Can I Have Different Paint Finish On My New Building?
We provide a protective treatment on all our buildings, but why not consider one painted with Sadolin (Diamond Buildings) or Valtti (Platinum Buildings) paint stains.. Both are available in various colours, so you can find a colour that suits you.
Be Careful When Buying A New Building
Before deciding on a new 12×20 summer house for your garden, you should always do your homework (sorry!) as it’s very easy to be taken in by a flashy website leaflet or colour brochure. Try to find time to visit our showroom, where you can see examples on display.
You will then be able to decide what you want to buy. We have a large collection of wooden buildings that you are welcome to view. We will be delighted to show you the different buildings and answer any queries you may have. We can also provide quotations.
Another thing to do is to take a look at the feedback from previous customers, which can be enlightening.
All our 1st Choice summer buildings can be made in sizes that meet your requirements. Just let us know what you would like, and we will quote for you. Don’t settle for second best—you know it makes sense.
These sunrooms can be made with internal partitions and extra doors, creating several different areas: one for leisure, one for storage, and one for the children. The choice is yours.
Why Not Consider An Integrated Shed Or Additional Room With Your Summerhouse?
Our Diamond and Platinum Buildings are available with an extra room to suit you. Whether it’s at the back, the side, or accessed from the front, we can make a summerhouse shed combo for you. Don’t compromise on what you would like to meet your requirements. Contact us NOW to chat through your needs, or visit us to see examples for yourself.
