Insulated garden room frames and glazing — perfect for home offices, studios, gyms, or entertaining spaces. Usable 365 days a year with proper insulation.
A garden room is a fully insulated, self-contained structure separate from your main house. Whether it’s a home office, studio, gym, or simply extra living space, a garden room gives you a dedicated, comfortable space — usable in every season.
Garden rooms have surged in popularity since 2020, and the demand has stayed. A practical, cost-effective alternative to extensions.
A quiet, professional workspace away from household distractions.
Art, music, photography, or craft studios with controlled lighting.
Your own private training space, steps from your back door.
Additional accommodation for family or visitors.
Cinema rooms, games rooms, or socialising space.
For therapists, beauticians, or wellness practitioners.

Most garden rooms fall under permitted development and don’t need planning permission, provided they meet certain conditions: they must be single storey, not exceed 2.5m in height if within 2m of a boundary (or 4m otherwise), and not cover more than 50% of your garden. Conservation areas and listed properties have additional restrictions. Always check with your local planning authority.
Yes, when properly insulated and fitted with double or triple glazing. Modern garden rooms are designed for year-round comfort. Combined with a small electric heater or underfloor heating, a well-insulated garden room maintains a comfortable temperature even in the depths of a Yorkshire winter.
Absolutely. A garden room is one of the best home office solutions available — it gives you physical separation from your living space, which helps with focus and work-life balance. They can be wired for electricity, broadband, and even plumbing if needed.
The glazing and fenestration components typically take 5-7 working days for stock colours. The overall build time depends on the complexity of the structure, foundation requirements, and interior fit-out. Most garden rooms are completed within 2-4 weeks from foundation to finish.
No. PTF Glass is a supply-only business. We supply glazing and fenestration components for garden rooms. We do not provide installation services. We can supply the windows, doors, and roof lanterns — your builder or garden room contractor handles the structure and fit-out.
