A garden office gives you something no spare bedroom or kitchen table ever can — a space that is genuinely separate from home life, designed from the ground up for focus and productivity. Ours are SIPs-insulated for year-round comfort, wired for modern work, and finished to a standard you'll be proud to have clients visit.
SIPs Soundproofing
Structural Insulated Panels provide excellent acoustic insulation — no road noise, no distractions.
Year-Round Climate
A-rated glazing and full SIPs insulation keep you comfortable all year. Add air conditioning or a smart panel heater.

Garden Offices We've Built
Why a Garden Office Changes Everything
No commute, no compromises
Walk 30 seconds from your back door to a dedicated workspace. No noise, no interruptions — just you and your work.
Better than a spare room
A proper, insulated, electrically certified structure is a business asset. It's also taxable as a home office expense — check with your accountant.
Adds value to your property
A well-built garden office typically adds 5–15% to property value — significantly more than its construction cost.
Clients can visit
A professional, finished space means you can invite clients without the awkwardness of working from your kitchen table.
What Makes Us Stand Out
Every Green Rooms build uses the same premium specification — regardless of price point.
Full ComparisonSIPs Construction
Structural Insulated Panels — far superior insulation, strength and soundproofing compared to timber frame. Warm in winter, cool in summer.
30+ Year Cladding
Thermo Ayous, Cedar, Charred Spruce, Hardie Plank, Millboard or Thermo Ash. Every material chosen for longevity. No Redwood, ever.
20-Year Roof Guarantee
EPDM or metal panel on every build — never felt. Both carry a 20-year guarantee as standard.
Fully Turnkey Service
Foundations, structure, cladding, glazing, electrics, flooring, plastering, and site clean-up all included. We hand the keys over on the last day — you walk into a finished room.
Electrical Sign-Off
Mains-connected consumer unit, full testing, and a signed electrical certificate included on every single build.
