What is a Modular Glass Extension?
A modular glass extension is an innovative building system, proudly manufactured in the UK, designed to create stunning, light-filled living spaces up to five times faster than traditional construction methods. It can be up to 60% more carbon efficient than standard brick walls, with zero production waste and minimal water usage on site.
At Clc Home, our modular glass extensions are individually designed and precision pre-engineered. Patented wall panels combining steel, timber, and high-performance insulation exceed Building Regulation standards. With slimmer profiles that allow more natural light and up to 15% additional floor space compared to traditional brick construction, each design feels brighter, more efficient, and truly bespoke.

Modular Advantage
Why Choose Modular?
Precision engineering, factory quality, and dramatic reduction in on-site disruption.
Factory-Built Quality
Around 80% of construction is completed in a factory rather than at your home. This allows for systematic inspections, no weather delays, and a level of precision difficult to achieve with traditional on-site construction.
Rapid Installation
On-site construction typically takes 2–4 weeks, compared to 3–6 months for traditional builds. Module installation itself can be completed in as little as 1–3 days.
Super-Insulated
Patented panels combining steel, timber, and high-performance insulation exceed Building Regulation standards. With an A++ thermal rating, they keep spaces warm in winter and cool in summer.
Bespoke Design
Individually designed with choice of roof options, window placements, and finishes – oak, aluminium, timber, or uPVC.

Modular Glass Extension FAQs UK
Common questions about modular glass extension costs, timing and installation in the UK.
A modular glass extension typically ranges from £30,000 to £80,000+, depending on size, specification, and complexity. Clc Home offers premium modular extensions from £30,000, fully installed with building control approval and a 10-year guarantee.
Total project timeline is typically 16-24 weeks from initial enquiry to completion. Design and planning (8-12 weeks), factory manufacturing (4-8 weeks), and on-site work (2-4 weeks). On-site disruption is reduced by up to 80% compared to traditional builds.
Yes. Our modular extensions feature patented wall panels with super-insulation, exceeding Building Regulations for thermal performance. They achieve A++ energy ratings and are comfortable year‑round.
Planning requirements are the same as for traditional extensions. Many modular glass extensions fall under Permitted Development Rights, though restrictions apply in conservation areas and on listed buildings. Clc Home provides full planning guidance with every project.
Yes. Thanks to the lightweight structure, modular extensions can often be built on existing conservatory bases, saving both time and cost. We assess suitability during the initial survey.
The on-site phase of a modular build is typically 2-4 weeks compared to 3-6 months for a traditional build. That’s around 80% less time with builders on your property. Because most construction happens in a factory, you avoid the ongoing dust, noise, and intrusion of traditional builds.
