IcoRoom Home Extensions

Building a home extension using traditional bricks and mortar often comes with rising costs, lengthy build programmes, site disruption, and unpredictable weather delays. With IcoRoom, Classic Windows brings you a smarter, highly engineered modern alternative. Whether you are seeking to convert an existing conservatory into an authentic, year-round living space or construct a brand-new single-storey extension from the ground up, IcoRoom delivers superior thermal efficiency, speed of build, and architectural distinction.

Engineered with an advanced modular timber pod system, IcoRoom combines precision off-site manufacture with robust on-site craftsmanship. The structure is 7× stronger than conventional timber frame and 3× stronger than traditional brick and block, while enabling installation up to three times faster. Complete with exceptional thermal performance—achieving wall U-values as low as 0.11 W/m²K and roof U-values down to 0.12 W/m²K—the IcoRoom is a lasting, energy-efficient investment that seamlessly enhances the value and comfort of your home.

Every IcoRoom is precision-crafted and tailored to your property’s exact proportions, fully complying with UK Building Regulations and supported by comprehensive structural calculations prior to delivery. Featuring a market-leading fully ventilated wall cavity system and proven Icotherm solid roof technology, IcoRoom prevents condensation and thermal bridging for total peace of mind in long-term performance. You have complete architectural freedom over external finishes—from authentic brick slips that mirror your existing masonry to contemporary render systems and modern composite cladding. Inside, fully plastered walls, perimeter pelmets, and options for concealed downlighting, roof lanterns, or Velux rooflights create a warm, inviting living room feel that can be enjoyed in supreme comfort through all four seasons.

Frequently Asked Questions About IcoRoom

1. Can IcoRoom be used to convert an existing conservatory as well as for new-build extensions?

Yes. The IcoRoom system is specifically engineered for maximum versatility. It can either replace and upgrade your existing conservatory walls and roof to create an authentic extension, or be constructed entirely from the ground up as a brand-new single-storey extension on suitable foundations.

2. How fast is an IcoRoom built compared to traditional brickwork?

Because the timber pods and modular components are precision-manufactured off-site in factory-controlled conditions, on-site assembly is up to three times faster than traditional brick and block methods. This drastically cuts down on wet trades, weather delays, and disruption to your daily home life.

3. Will the space be warm enough to use comfortably all year round?

Absolutely. IcoRoom delivers market-leading thermal efficiency, achieving wall U-values as low as 0.11 W/m²K and roof U-values down to 0.12 W/m²K. Combined with our fully ventilated wall cavity system, it keeps your room warm in winter, comfortably cool in summer, and completely protected against condensation.

4. Does IcoRoom comply with UK Building Regulations?

Yes. Every IcoRoom installation is supported by comprehensive structural calculations prior to delivery and meets all applicable UK Building Regulations. The structure is rigorously engineered—tested to be 7× stronger than standard timber frames and 3× stronger than brick and block masonry.

5. What external finishes and styling choices are available?

You have full architectural flexibility to match your existing property. Externally, choose between authentic brick slips, modern smooth render systems, or low-maintenance composite cladding. Internally, walls and pelmets are fully plastered ready for decoration, with options for integrated downlighters, roof lanterns, and high-performance glazing.
