The Modern Alternative to Traditional Extensions

Building an extension on your home with traditional bricks and mortar is becoming a thing of the past. There are several reasons for this, including rising costs putting them out of reach of many, a declining skills base to undertake the work, the disruption encountered whilst under construction and the lengthy time taken to complete, having to rely on the weather for time on site and the fact that modern material designs have enhanced wall systems to outperform traditional methods.

With an IcoRoom we offer a modern solution to either convert your existing conservatory into an extension or allow you to construct a new single storey extension in a sensible and affordable manner. Offering exceptional thermal values, our unfussy, clean systems are built to last and can be constructed in a matter of days in many cases.

We all know that the PVC conservatory we came to love in the 80's and 90's became a negative connotation in terms of the value or saleability of your home. With an IcoRoom, our solid Icowall system coupled with our solid Icoroof products produce the IcoRoom, a rock-solid investment in your home, adding the value to your property that a conservatory can never do.

Transform your existing conservatory or create a stunning new extension that genuinely adds value to your Bath or Bristol property. Unlike traditional conservatories, IcoRoom extensions are viewed by valuers and buyers as permanent, high-quality living space.

Built for Strength and Longevity

Just as with a traditional build you have all the external finish options that you may desire, whether that be cladding, render or brickwork which is created with the use of brick slips for example. And every one of our IcoRooms is fully structurally calculated before it arrives on site and complies with all building control legislation.

Our IcoRoom system provides a solid foundation for your large-scale projects, engineered to the highest standards and built to last for decades. Each installation is bespoke to your requirements and backed by comprehensive structural calculations.

Built in Weeks, Not Months

IcoRoom Extension FAQs

How long does it take to build an IcoRoom extension? +

IcoRoom extensions are built in weeks, not months. Thanks to off-site manufacturing and precision engineering, a typical IcoRoom extension in Bath or Bristol can be completed in 2-4 weeks depending on size and complexity. This is up to 3 times faster than traditional brick and mortar construction. The off-site manufacturing means weather delays are minimal, and on-site work is streamlined and efficient. Foundation work typically takes 3-5 days, the structure arrives pre-manufactured and is erected in days, followed by internal finishing. This rapid construction minimises disruption to your home and family life whilst delivering a superior final product.

Do I need planning permission for an IcoRoom extension in Bath? +

Many IcoRoom extensions fall under permitted development rights and don't require planning permission, subject to certain size and location criteria. However, properties in Bath's conservation areas, listed buildings, or where permitted development rights have been removed will typically need planning permission. IcoRoom extensions can be finished to match any architectural style, making them suitable even for sensitive planning areas. We conduct an initial assessment during consultation to determine planning requirements for your specific property and location. If planning permission is required, we can recommend experienced local architects and guide you through the application process. Building Regulations approval is always required for IcoRoom extensions, but as our systems are fully engineered and comply with all regulations, this is typically straightforward.

What are the thermal performance benefits of an IcoRoom? +

IcoRoom extensions deliver exceptional thermal performance that significantly outperforms traditional construction. Wall u-values can be as low as 0.111W/m2K and roof u-values as low as 0.12W/m2K - far exceeding Building Regulations requirements. This superior insulation means your IcoRoom extension stays warm in winter and cool in summer, with dramatically reduced heating and cooling costs. The fully ventilated wall system prevents condensation and moisture issues whilst maintaining thermal efficiency. Unlike traditional conservatories that are too hot in summer and freezing in winter, IcoRoom extensions create genuinely comfortable living space year-round. The advanced thermal performance also contributes to your property's EPC rating, making your Bath or Bristol home more energy-efficient and valuable.

Can I convert my existing conservatory into an IcoRoom? +

Yes, converting an existing conservatory into an IcoRoom extension is one of the most popular applications for our system. Many Bath and Bristol homeowners have conservatories that are too hot in summer, too cold in winter, and don't add value to their property. An IcoRoom conversion transforms this underused space into a valuable, year-round living area. The process typically involves removing the existing conservatory structure (the base and walls are often retained if suitable), installing the insulated IcoWall system and IcoRoof, and creating a properly insulated, habitable extension. This conversion usually qualifies as permitted development if the footprint doesn't change. The result is a space that looks and performs like a traditional extension but is built in a fraction of the time and often at lower cost.

What external finishes can I have on my IcoRoom? +

IcoRoom extensions offer complete flexibility in external finishes to match your Bath or Bristol home perfectly. Popular options include smooth or textured render in any colour, timber or composite cladding for contemporary aesthetics, brick slips that provide an authentic brick appearance indistinguishable from traditional brickwork, natural stone for period properties, or mixed finishes combining materials for architectural interest. The IcoWall system is designed to accommodate all these finish types, and because it's structurally superior to traditional construction, you have even more design freedom. We work with you to select finishes that complement your existing property, meet any planning requirements, and achieve your aesthetic vision. All finishes are applied to the same high standards and backed by appropriate warranties.
