Why Choose A 1st Choice 12 x 7 Summer house?

A 12×7 summerhouse from 1st Choice Leisure Buildings gives you plenty of space, lasting strength, and a look that fits your garden.

Use it as a garden office, extra storage, or a relaxing spot—it’s a flexible addition to your outdoor space.

These summerhouses are built with quality materials to handle all kinds of weather and still look great. Many flat-pack options can start to warp after a few seasons, but our sturdy build is made to last.

Careful craftsmanship means your investment will stand the test of time.

A well-designed summerhouse adds charm to your garden and creates a cosy spot to relax. Picture yourself having evening tea inside, enjoying the scent of wood and the sound of leaves.

Or set up a bright art corner for your kids. Choosing this summerhouse means adding special moments to your home.

Choosing A 12ft x 7ft Summer House From 1st Choice Leisure

When picking a summerhouse, make sure it’s built to last. Timber thickness matters, but in simple terms, it means your building will stay sturdy for many summers.

Choosing redwood instead of whitewood gives you more strength and less warping, so you spend less time on repairs. These details help ensure your summerhouse stays solid for years.

Are the doors and windows’ joinery made in a way that ensures they will last a long time? Does it have toughened glass for safety or imperfect horticultural glass, plastic, or perspex?

These are all important questions. In fact, 95% of our customers choose toughened glass for peace of mind, reaffirming its value in creating a secure environment.

Insulating My Summer Building

To enjoy your 7×12 building all year, consider adding lining and insulation. This keeps it cooler in summer and warmer in winter. You can do it yourself if you feel comfortable, or we can handle it for you.

Our service uses quality insulation and vapour barriers to keep your space comfortable in any season.

We can also insulate all Platinum buildings for you. It might feel like a luxury, but you’ll appreciate it during both hot summers and cold winters. As one customer said, “Best decision for year-round art studio.” Contact us for a free quote if you’re interested.

Free Installation Included As Standard On All Diamond & Platinum Buildings.

Many online summerhouses are delivered for you to build yourself. You might save some money, but putting it together can take up your whole weekend and be tricky if you make a mistake.

If you enjoy DIY, this could work for you, but most people find that having professionals handle the assembly is worth the extra cost for the time and effort it saves.

With 1st Choice, you get free assembly on Diamond and Platinum buildings. They handle all the hard work for you. All you need is a level base for your summerhouse, and if you want, the delivery team can help arrange that too.

This way, you can be sure your new building will be built correctly, and all you need to do is enjoy it.

This 12×7 Summerhouse Can Be Bespokely Made Just For You

We have a wide range of summerhouse sizes and styles for you to choose from. However, we specialise in making buildings to suit your needs through our exclusive 1st Choice Design Service.

Whether you need a taller summerhouse, extra or fewer windows, or doors and windows moved, 1st Choice can do that for you. With this service, you are not just choosing a building; you’re crafting an individual space tailored to your lifestyle.

Ensure you buy the building that suits you and your family without compromise. Call us on (01483) 237550 or visit our showroom to discuss your needs. We are happy to provide a quote that suits you without pressure.

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 12×7 summer house for your garden, it is crucial to thoroughly research your options. Online photos and flashy brochures often fail to capture important details like roof thickness, which can be a significant factor in the building’s durability and performance.

We understand these concerns and encourage you to visit our showroom, where you can see the quality of our summer houses firsthand and ensure you’re making a well-informed decision.

This way, you can see exactly what you’re getting. It’s like visiting a whole street of sheds in one spot. Our wide range of wooden buildings has something for everyone, and you’re welcome to come and look around. We’re happy to answer your questions and give you a quote.

Another thing to do is to take a look at the feedback from previous customers, which can be enlightening. “Excellent craftsmanship and timely installation,” praises Sarah from Guildford, highlighting the satisfaction with both product quality and service.

Another customer, John from Woking, mentions, “Our summerhouse has become the perfect backyard retreat,” emphasising its value as a personal sanctuary. Such testimonials reassure you of our commitment to providing high-quality and reliable summer buildings.

  • How Long Does a Summer House Installation Take?
    Most buildings are assembled in a single day if your foundation is prepared before construction, and depending on the project's size. Our team handles the design, preparation, and delivery of all materials off-site to keep things running smoothly. This efficient process lets us install your structure quickly and with minimal disruption.
  • How Long Does Delivery Take?
    Delivery times change throughout the year, but they are usually between 4 and 8 weeks. For the latest information, please visit our dedicated delivery page. If you need your order by a certain date, please contact us. We will do our best to help.
  • How Long Will My New Building Last
    The durability depends on several factors, including the quality of materials used, the level of maintenance, and exposure to environmental elements. Proper care and regular maintenance can extend its lifespan, while harsh weather conditions and neglect may shorten it. Ensuring that the structure is well-built and using high-quality materials can also contribute to its longevity. Regular inspections and prompt repairs as needed will help to prolong the life of your summer room. Pressure-treated timber is also a good option to choose. You can see some guidelines on this page.
  • Should I View Before Buying?
    When considering a purchase, it is advisable to view the product beforehand, as it allows for a firsthand evaluation of its condition and suitability.

    Viewing the item can provide valuable insights into its quality, features, and overall appearance, which may not be fully evident through online descriptions or images.

    This can help in making an informed decision and potentially prevent any future dissatisfaction with the purchase. Therefore, viewing the product before buying is a prudent step to take to ensure a satisfactory outcome.

    Our showrooms are open seven days a week, and we have over 60 buildings on display.
