4m x 4m Insulated Garden Room – Purpose (Silver)

£14,995.00

A spacious, fully insulated garden room designed for year-round use. Ideal as a home office, gym or therapy room, professionally installed at a fixed price.

Description

The 4m x 4m Insulated Garden Room – Purpose (Silver) is designed for customers who want a large, comfortable, year-round usable space without the cost and disruption of a traditional extension.

This is our largest fixed-price insulated garden room, making it ideal for use as a home office, personal gym, therapy or treatment room, studio or multi-purpose space. With full insulation throughout, it delivers excellent thermal performance and comfort in all seasons.

The structure is built using a pressure-treated structural timber frame and insulated throughout the walls, floor and roof. Externally, the building is finished with tongue-and-groove timber cladding, offering a clean, modern appearance that suits both traditional and contemporary gardens.

A durable EPDM rubber roof provides long-term weather protection with minimal maintenance. High-quality double-glazed doors and windows allow plenty of natural light while maintaining strong insulation and security.

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 gym equipment, desks, seating or therapy furniture.

This size and specification make the 4m x 4m Purpose Room a strong competitor to national garden room companies charging £17,000–£20,000+, offering outstanding value without compromising on quality.

Professional installation, waste removal and site tidy are all included in the fixed price.
