Working in Truro

Truro — Cornwall's only city — combines a Georgian and Victorian Lemon Quay centre with the cathedral quarter. Heritage timber sash work, listed-building consents, and commercial shopfront restoration across TR1-TR4 form our core local Cornwall services.

For doors and glass extensions in Truro, residential property style typically drives the design brief across South West — whether that's contemporary aluminium bifolds spanning a garden-facing rear elevation, slim-frame sliding doors that maximise glass area on a modern extension, or heritage French doors fitted to a period façade. Most commonly we're working across TR1 and TR4 postcodes. Typical lead time from survey to install: 4-6 weeks for standard configurations, 8-10 weeks for bespoke or large-span builds.

Our process

How we deliver in Truro

01

Architectural consultation

We visit your home, discuss your vision, and produce concept sketches and CAD plans. For complex projects we can introduce you to our partner architects.

02

Engineering & planning

Structural glass extensions require specialist structural calculations and (usually) planning permission. We handle both — typical timeline 8-12 weeks from concept to consent.

03

Manufacture

Glass panels are toughened and laminated to structural specifications (often 24-32mm thick). Lead times 6-8 weeks. Steel structure (if exposed) manufactured in parallel.

FAQs

Common questions

Frameless glass box extensions typically cost £25,000-£60,000 depending on size and complexity. Cost per square metre is roughly double a conventional brick extension.
We specify solar-control glass that reflects 60-70% of solar heat, often combined with electrochromic or external venetian blinds. Combined with cross-ventilation through bifold or sliding doors, modern glass extensions are comfortable year-round.
Larger glass extensions usually need planning permission, but smaller projects may qualify as permitted development. We assess each project at the survey stage.
