Our Cube designs give you a clean, modern way to add practical space to your garden. Whether you need a focused home office or a flexible room to use year-round, we build it properly – from first design through to final finish.
A Cube garden room is one of the simplest ways to create extra usable space without extending your house. The square, flat-roof design keeps things clean and modern while maximising internal floor area.
It’s a practical solution for homeowners who want:
A dedicated home office
A gym or training space
A studio or hobby room
A quiet room away from the main house
No unnecessary detailing. No overcomplication. Just a solid, well-built space that does what it’s supposed to do.
We had our 3.5×3.5m room built in March. We absolutely love it and can’t recommend this company enough. We had issues with our garden drainage so have only just had nice garden grass to take a picture!

Our price list? It’s just a starting point. At Contemporary Garden Rooms, we’re big on making your unique visions come to life. Want something beyond standard sizes or
features? You’ve got it. We specialise in crafting spaces that fit your exact needs, from custom dimensions to personalised touches. Let’s create something uniquely yours. Because ‘ordinary’ isn’t in our vocabulary.
A garden room should work in January as well as July.
Our Cube garden rooms are fully insulated throughout the walls, floor and roof, with proper foundations and durable external finishes. Combined with quality glazing and heating options, this creates a space that feels like a real room — not a seasonal outbuilding.
You get:
Full insulation package
Strong, stable foundations
Internal plastered finish ready to decorate
Proper rainwater management
It’s built once and built properly.
Designed around your space
The cube format works well in most gardens because it keeps proportions balanced and makes efficient use of the footprint available.
We design each build around:
Your garden layout
Access and orientation
The intended use of the room
The look of your existing property
Large glazed doors, anthracite frames and clean cladding lines give the structure a modern finish without being overdesigned.
Built on site by our joiners
All Cube garden rooms are constructed on site by our own team. This allows us to maintain build quality, ensure structural integrity and avoid the compromises that can come with pre-fabricated kits.
From foundations to final fix, everything is handled as one clear process.
