3m x 3m Insulated Garden Room – Purpose (Silver)
£10,995.00
A fully insulated, year-round garden room ready for use as a home office, gym or studio.
Description
The 3m x 3m Insulated Garden Room (Purpose – Silver) is designed to provide a comfortable, year-round usable space that feels like a natural extension of your home. It’s ideal for customers who want more than a basic garden building and need a room suitable for working, exercising, relaxing or creative use in all seasons.
This garden room is constructed using a pressure-treated structural timber frame and fully insulated throughout the walls, floor and roof. High-performance insulation helps regulate temperature, keeping the space warm in winter and cooler in summer, making it suitable for daily use rather than occasional storage.
Externally, the building is finished with tongue-and-groove cladding for a clean, modern appearance, while the EPDM rubber roof provides long-term weather protection with minimal maintenance. High-quality double-glazed doors and windows allow natural light into the space while maintaining excellent thermal performance.
Internally, the room is supplied with plasterboarded walls, creating a smooth, modern finish ready for decorating. The insulated timber floor provides a solid base suitable for office furniture, gym equipment or general use. This makes the Silver range a significant step up from standard garden buildings.
Professional installation is included, along with waste removal and site tidy, giving you a clear fixed price from the outset with no hidden extras.
