What is the difference between a timber sunroom, a conservatory, and an orangery?

A sunroom features a solid vaulted or pitched roof (often tiled to match your existing home) with large vertical timber-framed windows and optional rooflights. A conservatory has a fully glazed roof, while an orangery combines an insulated flat roof perimeter with a central glass lantern. Sunrooms provide the highest thermal mass, making them feel most like an organic, built-in extension of your main house.

Can a hardwood sunroom be used as an open-plan kitchen and dining extension?

Yes. In fact, opening up segmented ground floors to create a unified kitchen, dining, and family living space is our most requested project. A sunroom's solid roof structure and timber columns easily support kitchen cabinetry, high-span steelwork, and recessed lighting while flooding the cooking and dining zones with natural light.

Will a hardwood sunroom feel like a seamless part of my house?

Absolutely. Because we match the exterior masonry, brickwork, and roof tiles to your host property, a James Alexander sunroom looks as though it was built alongside the original home. Inside, continuous flooring, plasterboard vaulted ceilings, and underfloor heating make it feel like a natural continuation of your ground floor.

Do I need planning permission for a hardwood sunroom extension?

Many single-storey sunrooms fall under Permitted Development rights, provided they stay within specific height, footprint, and boundary guidelines. However, if your property is listed, in a Conservation Area, or within an Area of Outstanding Natural Beauty (AONB), planning permission or Listed Building Consent may be required. We handle all site surveys, architectural drawings, and planning applications on your behalf.

Why build a sunroom with Sapele hardwood instead of softwood or uPVC?

Sapele is a high-density, Class 2 durable hardwood that resists rot, warping, and seasonal movement better than softwoods or unseasoned oak. Unlike uPVC, which lacks structural depth and character, Sapele allows for crisp, historic joinery detailing that lasts 30+ years when finished with our factory-applied microporous paint system.

Are sunrooms warm enough for mid-winter use without high heating bills?

Yes. With a fully insulated timber or slate roof, insulated dwarf base walls, and high-performance double glazing featuring Low-E coatings and argon fills, a sunroom boasts exceptional U-values. It retains heat just like a conventional room in your house, ensuring year-round comfort.
