Work. Create. Relax. Bespoke, insulated garden rooms you can enjoy all year round.
At 1st Builders Cambridge, we create bespoke garden rooms that provide the perfect balance between style, comfort and practicality. A garden room is a versatile solution that allows you to make the most of your outdoor space while adding real value to your property.
Whether you need a private home office, a fully equipped gym, a creative studio, or simply a quiet retreat away from the main house, we design and build insulated garden rooms tailored to your needs. Each structure is carefully planned to ensure it is usable all year round, with excellent insulation, lighting and finishes that make it feel like a natural extension of your home.
From the first design consultation to the final installation, our team manage every stage of the process. The result is a stylish, functional space that blends seamlessly into your garden and provides comfort, privacy and flexibility for years to come.
A bespoke garden office is the ideal way to work from home. Insulated for year-round comfort, with power and internet installed, it offers a quiet, professional space free from distractions. Just steps away, it helps you stay productive while keeping a clear balance between work and home life.
A bespoke garden room can be anything you need – a bright studio for painting or music, or a peaceful retreat for reading, yoga or simply unwinding. Designed with comfort and focus in mind, it's fully insulated, private and seamlessly integrated into your garden. The perfect space to create, relax and escape everyday distractions.
A garden gym gives you the convenience of training at home. With reinforced flooring, ventilation and the right power supply, it's perfect for cardio, strength or yoga. No commuting, no waiting – simply a private, well-designed space to focus on your health and wellbeing.
In most cases, no. Garden rooms often fall under ‘Permitted Development’ rights, provided they meet certain criteria regarding size, height, and distance from your property boundary. We will assess your specific situation and advise you on whether any permissions are needed.
Yes, we can incorporate plumbing for a small bathroom or a simple kitchenette. This requires more extensive groundwork to connect water and waste services, but it's a great way to create a fully self-contained space.
A solid, level base is essential for the longevity of your garden room. We typically recommend either a concrete slab or a ground screw foundation system. We will assess your garden's ground conditions and advise on the most suitable and cost-effective option.
Absolutely. We build our garden rooms to be used comfortably throughout the year. They are fully insulated using high-quality materials in the floor, walls, and roof, and we fit double-glazed windows and doors as standard.
Yes, we can handle all the electrical work required. This includes running a safe, armoured cable from your house to the garden room to power lights, sockets, and heating. We can also help you set up a reliable internet connection.
Our garden rooms are fitted with high-quality, insurance-approved locks on all doors and windows as standard. The double-glazed units are also internally beaded, which prevents them from being removed from the outside.
While a detached garden room is a standalone structure, we can certainly build an attached garden room. This would be classified as a house extension and would need to comply with building regulations for thermal efficiency and fire safety between the two structures.
Yes, we offer a wide range of cladding to suit your style and budget. Popular choices include natural woods like cedar and larch for a warm, traditional look, as well as low-maintenance composite cladding which comes in various colours and finishes.
