What Is an Orangery or Garden Room?
An orangery is a brick-built extension with a flat roof perimeter and a central glazed lantern roof, creating a light-filled living space that feels more substantial than a conservatory but brighter than a traditional extension. Garden rooms are standalone insulated structures in your garden, perfect for home offices, gyms, or entertaining spaces.
At JBW Construction, we build orangeries as permanent, structural additions to your home — with proper foundations, cavity walls, building regulations compliance, and full integration with your existing heating system. Unlike conservatories, our orangeries are usable 365 days a year with consistent temperatures and no overheating in summer.
Garden rooms are built to the same quality standards: insulated timber frame or SIP panel construction, double or triple glazing, underfloor heating, full electrics, and finishes that match your home. They add genuine usable space and property value.
Why Cheap Conservatories & Garden Buildings Fail
Standard conservatories are too hot in summer, too cold in winter, and add minimal value to your property. Their lightweight construction, single-glazed polycarbonate roofs, and lack of insulation make them unusable for half the year. Estate agents routinely exclude conservatories from floor area calculations.
Cheap garden buildings from big-box retailers are equally problematic: thin timber walls, no insulation, inadequate foundations, and electrical installations that don't meet building regulations. Within 2-3 years, they suffer from condensation, timber rot, and structural movement.
Our orangeries and garden rooms are built to building regulations standards with proper foundations, insulated walls, and quality glazing — creating spaces that are genuinely usable, add measurable value, and last decades.

Why Choose Us
Why Choose JBW for Your Orangery or Garden Room
Usable Year-Round
Properly insulated walls, high-performance glazing, and integrated heating mean your orangery is comfortable in every season — unlike a conservatory.
Adds Real Property Value
Orangeries are valued as permanent extensions by estate agents and surveyors, typically adding 1.5-2x their cost to your property value.
Bespoke Design
Every orangery is designed specifically for your property, matching brickwork, roofline, and proportions for a seamless, sympathetic addition.
Bi-Fold & Sliding Doors
Open your orangery to the garden in summer with aluminium bi-fold or sliding door systems in a range of colours and configurations.
Lantern Roof Options
Glazed lantern roofs flood your orangery with natural light while the insulated flat roof perimeter provides excellent thermal performance.
Full Building Regulations
Unlike conservatories, our orangeries comply with building regulations — essential for insurance, mortgage, and resale purposes.
Orangery & Garden Room Specifications
Orangery Construction
Our orangeries feature cavity wall construction with full-fill insulation, matching brickwork or stonework to your existing property, and engineered flat roof perimeters with a central glazed lantern. Foundations are designed by our structural engineer to suit your ground conditions. The result is a permanent, thermally efficient addition that adds genuine living space.
Garden Room Construction
Standalone garden rooms use timber frame or SIP (Structural Insulated Panel) construction on concrete pad or screw pile foundations. Walls achieve U-values comparable to new-build housing. External cladding options include timber, composite, render, or stone to match your property and garden setting.
Glazing & Doors
We install aluminium or timber bi-fold doors, sliding patio doors, and fixed glazing from leading manufacturers. Standard specification is argon-filled double glazing with low-E coatings. Triple glazing is available for maximum thermal and acoustic performance.
Heating & Electrics
Orangeries connect to your existing central heating system with underfloor heating as standard. Garden rooms typically use electric underfloor heating or air-source heat pump units. Full electrical installation includes lighting, power sockets, and data cabling.
Planning & Permitted Development
Many orangeries and garden rooms fall under permitted development rights, meaning no planning application is needed. Key limits include: single-storey, no higher than 4m, no more than half the garden covered. We confirm your PD rights during the design stage and handle any applications if required.
