THE PROJECT
From an idea
to a real space.
A cedar-clad SIP garden studio in Brentwood, with integrated storage and a design shaped around the garden.
This bespoke SIP-panel garden room was designed and built in Brentwood, Essex for a client who wanted a premium outdoor space with practical hidden storage and front composite decking.
• A high-end garden room • Natural red cedar cladding • Large sliding doors • Integrated storage room • A discreet “secret” access door • Composite decking to the front • Full electrics throughout
We delivered a turnkey solution — designed, built, wired, and fully finished.
The structure was built using our high-performance SIP panel system, ensuring:
The exterior was finished in Western Red Cedar cladding, giving the building a warm, premium appearance that will gracefully silver over time.
Large aluminum sliding doors flood the interior with natural light while maintaining excellent insulation.
One of the standout features of this project was the integrated storage room, accessed through a discreet, concealed door.
From the outside, the building appears seamless and minimal — but inside, the client benefits from a fully functional storage space without compromising the clean architectural lines.
To complete the outdoor experience, we installed a durable composite decking area to the front of the building.

Brilliant craftsmanship! "Costi and his team built a garden room at the back of our garden, put down some composite decking and fitted out our utility room. They were brilliant from start to finish – Costi provided a very detailed quote, was very responsive and helpful and the team completed the job efficiently and with no fuss (and cleaned up thoroughly after the job was completed). The workmanship was excellent and we would not hesitate to recommend Costi and his team to anyone looking for professional builders.”
