Modular Garden Rooms for all Outdoor Spaces
At The Green Room, we keep things simple and clear. Whether you’re creating a granny annexe or one of our garden lodges, you’ll always know what’s happening and when.
Choosing a granny annexe or garden lodge is a big decision, but the process doesn’t have to be complicated. At The Green Room, we keep things clear and easy to follow from start to finish. Our team is with you every step of the way, from your first ideas right through to the final handover. Here’s how it works.
From first ideas to the day we hand over the keys, we keep the process straightforward and stress-free. Here’s how we guide you through your garden room or granny annexe project.
We start with a friendly call to learn more about your space and what you need. From there, we’ll offer honest advice and book a free site visit if you’re ready. You can also get started now with a free granny annexe quote.
Our team will visit and assess your garden. We check space, drainage, access, and ground levels. If planning permission is needed, we’ll let you know and explain your options clearly.
Next, we provide a clear fixed-price quote with a layout tailored to your needs. We’ll show you kitchen styles, cladding options, flooring and other finishes so you know exactly what’s included.
We handle all the planning or lawful development paperwork for you. This includes drawings, applications and local authority contact. You don’t need to deal with the council directly. To learn more about planning, visit our Garden Annexe FAQs.
When planning is approved, we book your build. Our in-house team completes the job from foundations to finish. Most builds take around 3 to 6 weeks depending on the size. We use screw pile foundations, SIPs panels and include all plumbing, electrics, flooring, and fittings.
We walk you through the finished space, check everything is working and make sure you’re completely happy. You’ll receive your documents, certificates, and keys to your new space. It’s ready to move into from day one.
Every granny annexe we build is carefully planned and professionally installed by our experienced team. From start to finish, we manage the full process for you. Below is a simple breakdown of the key steps that bring your annexe to life.
We begin by installing strong screw pile foundations. This system is approved by Building Control and gives a secure base for your annexe. It’s quick, clean and works well even on sloped or soft ground.
Once the foundations are in place, we move on to the main structure. SIPs panels (structurally insulated panels) are used to build the floor and walls. These panels are precision-cut and go up fast, giving excellent insulation from day one.
With the structure up, internal battens are added to support fittings and finishes. Electrical wiring and service runs are also placed during this stage, ready for your sockets, switches, and lighting.
Next, the inside is plaster boarded and fully plastered. This gives a clean, smooth finish throughout the space. It’s now ready for you to decorate however you wish.
Your choice of external cladding is added, whether it’s Western Red Cedar or low-maintenance fibre cement board. This gives the annexe its final look and protects it from the weather for years to come.
At this point, the kitchen, bathroom and flooring are installed. Fixtures like radiators, LED lighting, switches, wardrobes, and appliances are fitted. Everything is made to match your chosen layout and finish.
Your granny annexe is now complete and ready to use. Fully insulated, connected to services, and finished to a high standard inside and out. All that’s left is to move in.
Once you’ve submitted your quote request, we’ll get in touch to arrange a free site survey. This helps us understand your space, needs and budget so we can offer the right solution.
