Bespoke Insulated Garden Room for Year-Round Home Working
Nathan approached Stagbrook with a clear goal: to create a fully insulated, purpose-built garden office that would feel as comfortable and refined as an indoor space, while adding long-term value to his property.
Working at his home in Sevenoaks, Kent, we designed and constructed a high-spec timber-framed garden room tailored to year-round use, combining structural integrity, energy efficiency and contemporary design.
The Brief
A quiet, dedicated home office separate from the main house
Fully insulated for year-round use
Low-maintenance exterior
Professional finish inside and out
Minimal disruption to the household during construction
Our Approach
We treated this project exactly as we would a permanent extension, not a “shed conversion.”
Project duration: 4 weeks from groundwork to handover
Planning considerations: Designed within permitted development guidelines
Groundworks: Reinforced concrete base for structural longevity
Structure: Timber-framed construction with breathable membrane system
Insulation: High-performance insulation in walls, roof and floor
Exterior finish: Premium cladding for durability and clean aesthetics
Roofing: EPDM rubber roofing system with extended lifespan
Windows & Doors: Double-glazed anthracite aluminium units
Electrical: Fully wired with LED lighting, sockets and data points
Interior finish: Plaster boarded, plastered and decorated to a high standard
Every stage was managed in-house by our experienced team, ensuring consistency, quality control and clear communication throughout.
The Result
The finished garden office is warm, quiet and professionally finished, a true extension of the home rather than an afterthought. It blends seamlessly into the surrounding garden while providing a dedicated, distraction-free workspace.
Nathan particularly valued:
Our tidy site management
Clear timeline and cost transparency
Quality of workmanship
Efficient turnaround
And yes, the ginger dog approved too 🐾
