Summer Houses Windsor – Quality Garden Summerhouses

Looking for quality summer houses in Windsor? I’m Robin Antill, founder of 1st Choice Leisure Buildings, and I’ve worked with timber garden buildings since starting Marina Sheds in 1979. Our Windsor summerhouses include traditional, contemporary, corner, painted and insulated designs for relaxing, hobbies, entertaining or working from home.

My advice is to compare the timber, framing, floor, roof, glazing and overall construction rather than choosing on appearance or price alone. Browse the summer houses below, with professional assembly available on our principal ranges, or visit our Surrey display site to compare representative garden buildings before deciding.

A modern summer building. Perfect in Windsor for a summer room or relaxation space.

Choosing the Right Summer House for Your Windsor Garden

After working with garden buildings since 1979, I have learnt that choosing the right summerhouse starts with deciding what you actually want the building to do. A peaceful place to sit and enjoy the garden during warmer weather has very different requirements from a home office, hobby room or building you expect to use regularly throughout the year. If you are comparing summer houses in Windsor, decide on the intended use first and then compare the size, construction and specification needed for that purpose.

I also recommend measuring your available garden space carefully before ordering. Mark the proposed footprint on the ground and allow room around the building for installation and future maintenance. Consider which way the doors will open, where the glazing will face, and what you will see while sitting inside. A well-positioned summerhouse can be far more enjoyable than a larger building squeezed awkwardly into the garden.

What Should You Look For When Buying a Summer House?

My advice is to look beyond the photograph and headline price. Two summerhouses can look remarkably similar online but differ significantly in timber, framing, flooring, roofing, doors, glazing, and overall construction. These details help explain why one building may cost more than another, and whether the extra specification is worthwhile for how you intend to use it.

Check exactly what is included as well. Professional assembly is available on our principal summerhouse ranges, subject to the individual model, delivery area, suitable access and base requirements. I would always rather somebody understood the complete specification and price before ordering than discovered afterwards that an important part of the building or installation was not included.

Which Type of Summer House Is Best for Your Windsor Garden?

Traditional Summer Houses

A traditional timber summerhouse can be ideal for relaxing, reading, entertaining friends, or simply enjoying your Windsor garden while sheltered from the British weather. If that is your main requirement, you may not need to pay for a specification intended for regular winter use. You can compare different sizes and styles within our complete summer house range.

Insulated Summer Houses

If your new building is intended as a home office, studio, hobby room or somewhere you expect to use regularly during colder weather, insulation becomes much more important. Our insulated summer houses include options designed for customers wanting greater comfort and more frequent use throughout the year.

Corner Summer Houses

A corner summerhouse can be a particularly useful choice if you want to make use of an otherwise awkward part of the garden while keeping more of the lawn or patio open. The angled frontage can also provide attractive views back across the garden. Browse our corner summer houses if this layout suits your Windsor garden.

Painted Summer Houses

A painted summerhouse can complement your house, fencing, garden furniture and planting and can make the building feel more integrated with its surroundings. Depending on the individual model, a range of factory-applied or specified colour options may be available. You can compare suitable designs in our painted summer houses range.

Summer Houses With Shed Storage

If you would like somewhere attractive to relax but still need practical garden storage, a combination building may save valuable space. Our summer houses with shed storage combine a leisure room with a separate area for tools, bicycles, garden furniture and other equipment.

Why My Experience With Garden Buildings Matters

I’m Robin Antill, founder of 1st Choice Leisure Buildings. I left school at 15 and started my first garden building business in 1979, trading as Marina Sheds. In those days, you dealt directly with customers and learnt quickly that the quality of the timber, floor, roof, framing, and doors mattered far more than clever marketing.

I sold Marina Sheds in 1990. Unfortunately, I did not receive all the money I was due from the sale. It was a difficult business lesson, but it certainly did not end my involvement with garden buildings.

In 1992 we broadened the business beyond sheds by adding summerhouses, garages, garden rooms and log cabins. That change of direction led to a new name, Titan Garden Buildings. My son Craig joined me in 1992 after studying carpentry at Guildford College from 1990, bringing practical woodworking knowledge and an understanding of timber construction into the business.

We sold Titan Garden Buildings in 1998. In 2000, Craig and I decided that rather than manufacture everything ourselves, we would retail quality garden buildings from selected manufacturers. That decision led to the formation of 1st Choice Leisure Buildings and meant we were able to compare different ranges, specifications and price points rather than trying to make one manufacturer’s products suitable for every customer.

Today Craig runs the day-to-day business, and I am there to support him and the team whenever required. My experience goes back more than four decades, but its value isn’t simply the number of years. It is being able to use what I have learnt to help customers understand the differences between buildings and choose a specification suitable for their needs rather than automatically directing them towards the cheapest or most expensive option.

Can You See Our Summer Houses Before Buying?

Yes, and whenever practical I recommend doing so. Photographs are useful for comparing designs, but they cannot properly show the feel of a timber floor, the strength of the framing, the construction of the doors, internal proportions or differences between alternative specifications. Our Surrey display site has representative garden buildings available to inspect before you make your decision.

We cannot display every model, size and option we offer, but seeing representative buildings can help you understand the differences between ranges. You can find details of our Surrey garden building display site before travelling.

Summer Houses Windsor – Quick Answers

Do You Supply Summer Houses in Windsor?

Yes. We supply a wide selection of summer houses to customers in Windsor, including traditional, contemporary, corner, painted and insulated designs. Professional assembly is available on our principal ranges, subject to the individual model, delivery area, suitable access and base requirements.

What Size Summer House Should I Choose?

Choose a building that provides enough usable internal space without overwhelming your garden. Mark the proposed dimensions on the ground before ordering, and allow space for furniture, movement inside the building, door opening, installation access, and future maintenance. The largest size that physically fits is not automatically the best choice.

Do I Need an Insulated Summer House?

Not necessarily. If you mainly want somewhere attractive to relax during spring, summer and pleasant autumn days, a quality conventional timber summerhouse may be perfectly suitable. If you intend to work inside regularly, pursue hobbies throughout winter or use the building as an additional room, an insulated specification is usually worth considering.

Can I Order a Bespoke Summer House for Windsor?

Bespoke options are available on selected ranges. Depending on the particular manufacturer and model, changes may be possible to the size, doors, windows, layout and other details. This can be useful if you have an awkward garden position or need the building configured around a particular use.

Are Your Summer Houses Professionally Assembled?

Professional assembly is included or available on applicable principal ranges, subject to the model, delivery location, suitable access and preparation of the base. Always check the individual product specification and installation requirements before ordering.

What Is Most Important When Comparing Summer Houses?

I recommend comparing the complete specification rather than price alone. Look at timber quality, framing, wall construction, floor, roof, doors, glazing, treatment, installation and precisely what is included in the advertised price. These details often reveal significant differences between summerhouses that initially appear similar online.

Who Is Robin Antill?

I am the founder of 1st Choice Leisure Buildings and have worked with garden buildings since starting Marina Sheds in 1979. I later developed Titan Garden Buildings before Craig, and I formed 1st Choice Leisure Buildings in 2000. Craig now runs the business day-to-day, and I continue to support him and the team with the knowledge and experience I have gained throughout my working life.

Need Help Choosing a Summer House in Windsor?
