The Claremont – CDR Range

Beautifully Built. Designed to Last.

Transform the way you live and work at home with a contemporary garden room from Outdoor Modular Spaces. Each building is crafted in the UK by skilled builders using premium materials and precision-engineered construction. Whether it’s a home office, gym, studio, or relaxation space — your OMS garden room is designed to be enjoyed year-round and built to last for decades.
 

Structure & Insulation

Every OMS garden room is constructed using C24 structural timber, built to UK Building Regulations for long-term strength and stability. Walls, floor, and roof sections are fully insulated with PIR insulation board (Celotex or similar) for excellent thermal performance, and properly ventilated, keeping the space warm in winter and cool in summer.
 

Cladding

The front elevation features Western Red Cedar tongue and groove cladding — a premium, naturally durable timber known for its warm tones and rich character. Side and rear elevations can be finished in composite or profiled steel cladding, providing a contemporary, low-maintenance finish that requires no treatment.
 

Doors & Windows

All garden rooms include a 2m wide set of double-glazed French or sliding uPVC doors, available in Anthracite Grey, Black, or White. 

The Claremont design includes as standard a 600mm x 800mm fixed side window, adding extra natural light.

All windows & doors feature argon-filled, low-e coated double glazing for superior insulation and energy efficiency, along with trickle vents for ventilation.

An upgrade to aluminium doors and windows is also available for a more architectural finish.
 

Roofing & Guttering

Each building is fitted with a high-performance EPDM rubber roof designed for longevity and zero maintenance. The roof features a powder-coated aluminium fascia to the front for a clean, modern edge and includes rear guttering and downpipe for efficient water drainage.
 

Flooring & Interior Finish

Inside, the space is finished to the same high standard as a new home. Features include 8mm premium laminate flooring with underlay, skirting, plastered walls and ceilings, integrated LED downlights, and a wall-mounted electric radiator. Every room is bright, comfortable, and ready to use from day one.
 

Electrical Specification (Included as Standard)

Electrics are installed and certified in accordance with NICEIC certification.

Footings (Included as Standard)

A thorough site inspection is carried out by our team prior to foundation installation. We evaluate factors including adjacent trees and their root systems, existing vegetation, site access, soil conditions, and any pre-existing foundations. Based on this assessment, we will determine which of the following foundation systems is most appropriate for your building:

• Galvanised 1250 mm ground screws – a modern, low-impact solution that avoids large amounts of concrete, minimises soil disturbance and is ideal for use near trees and root systems. 
• Concrete pads – traditional, stable and cost-effective where site conditions allow clear access and level ground.
• Reinforced concrete raft – a heavy-duty base option for challenging ground conditions or where a permanent, highly robust base is required.

By making this decision ourselves, we ensure the foundation solution is matched to your plot and delivers optimal longevity, stability and minimal disruption to your garden.
