Insulated buildings
Performance you can feel
A garden room is only as good as its envelope — we build insulation into every layer, not as an afterthought.
Our insulated garden buildings use premium materials throughout the structure: PIR or mineral wool in walls and roof, insulated floor systems, and carefully sealed junctions that eliminate cold bridging. Breathable membranes manage moisture whilst vapour control layers protect the building fabric long term.
The result is a space that stays warm on a Hertfordshire winter morning and comfortable on a summer afternoon — without excessive heating costs. Combined with efficient underfloor heating or air-source systems, your garden room becomes a genuine extension of your living space, usable every day of the year.

What our clients say
“From the first consultation to the final handover, the team were meticulous. Our garden office has transformed how I work from home — quiet, light-filled, and completely separate from the house.”
“We wanted a cedar-clad studio that would sit naturally in the garden, not something that looked bolted on. The craftsmanship is exceptional — the glazing, cladding, and interior finish are all flawless.”
“Our garden gym needed to be properly insulated and well ventilated. They specified everything thoughtfully and the bi-fold doors make it feel open in summer and cosy in winter. We use it every day.”
“A garden annexe with two young children at home sounded ambitious, but they managed the project brilliantly. The space is exactly what we imagined — practical, beautiful, and built to a very high standard.”
