Garden Rooms Sunningdale
Building a garden room is a really smart, seamless way to expand your home’s usable space. Our custom timber garden rooms provide a magnificent, detached sanctuary for entertaining guests or private relaxation, specifically scaled and styled to enhance the sprawling, manicured garden plots that characterize the local luxury estates.
For the construction, we only use the highest-quality materials. For example, insulated timber frames and durable, attractive cladding (such as cedar or composite). Looking to keep out the cold? Let's add double-glazing and full insulation, ensuring you can use the room all year round.
A garden room provides the ideal, distraction-free environment regardless of your intended use. Investing in one not only enhances your lifestyle but also increases your property’s value, offering the ultimate blend of indoor comfort and garden tranquility.


Garden Office Sunningdale
Eliminate the daily commute from Sunningdale station by establishing an architectural, high-speed connected garden workspace that offers complete acoustic isolation from the main residence, providing corporate directors and executives with a private boardroom-tier environment.
Designed to the highest standards, our offices are constructed with high-performance double-insulation, composite wood clading, and a range of I.T. considerations. Regardless of the season, we want to ensure your Sunningdale home office is comfortable and works for you.
A garden office is more than just a desk space; it is a serious investment in your career and well-being. This is the ultimate way to physically separate your work from your home, to gain a professional, focused, and mdoern workspace, maximizing both your output and your enjoyment of your home life.
Garden Studio Sunningdale
Drawing inspiration from the beautiful, mature pine and heather landscapes of the surrounding area, our bespoke garden studios utilize premium structural glazing to maximize natural light, creating an inspiring layout for art, fitness, or personal well-being.
These self-contained spaces are the ideal retreat to further explore your hobbies, focus on your fitness, crank the music up, or manage your side-hustle.
Built for all-season use, our garden studios feature only the highest quality materials, as well as being eco-friendly and sustainable. Insulated with double-glazed windows, your studio will be warm, confortable, and be an inspiring environment all year-round.


Garden Gym Sunningdale
Design a private, climate-controlled fitness pavilion right outside your back door, structurally reinforced with heavy-duty framing to safely accommodate professional-grade cardio machinery, free weights, and dedicated personal training zones.
In fact, the popularity of garden gyms has grown exponentially across the last decade as the benefits they offer are unambiguously clear. This is more than just a garden shed. It is a professional, fully insulated fitness studio built just steps from your back door.
The accessibility makes this infinitely more convenient allowing you to integrate it far easier into your daily life. You can also design the gym to fit all your needs. Need reinforced flooring? Want specialist ventilation units? You name it, we've most likely built it.
