The HUP! system offers revolutionary, certifiable advantages over traditional building methods
The HUP! (a home extension and conservatory building) system is rapidly transforming the construction landscape, particularly for extensions, conservatories, and modular builds. By combining the speed of modern methods of construction (MMC) with the structural integrity of traditional brick-and-mortar, it addresses the most common pain points of building.

Custom Finishes and Material Matching for HUP
The HUP! system uses advanced, lightweight structural insulated panels (SIPs) for speed and thermal efficiency. Externally, we offer full customisation to ensure the extension matches your existing property. Options include a variety of brick slips (to mimic your home's original brickwork), modern coloured renders, and high-quality timber or fibre cement cladding. We also integrate your chosen windows, bi-fold, or patio doors seamlessly into the pre-cut panels.
Internal Customisation and Roofing Options
Internally, the high level of insulation reduces the need for excess heating. We complete the interior with full plastering, ready for decoration. Roofing options are highly flexible, including durable, tiled warm roofs (pitched) or modern, seamless flat roofs (EPDM/GRP) which can incorporate large roof lanterns or skylights to flood the new space with natural light. Every element, from the foundations to the final finish, is managed by our certified HUP! installers.

Frequently asked questions
A HUP! extension is dramatically faster than traditional brick-and-block construction. While a conventional extension of similar size can take 12–16 weeks on site, our HUP! system typically reduces the build phase to just 4–6 weeks. The prefabricated structural insulated panels (SIPs) arrive ready to assemble, eliminating wet trades, extended drying times, and weather delays.
Yes, absolutely. As certified HUP! installers, we manage the entire building control approval process on your behalf. The HUP! system is fully compliant with UK Building Regulations and has a recognised LANTAC (Local Authority National Type Approval Confederation) certification, which can significantly streamline the local authority approval process across Norfolk, Suffolk, and Cambridgeshire.
The structural life expectancy of a HUP! extension is comparable to, or exceeds, that of a traditionally built home. The SIPs panels are engineered to provide superior structural performance, and the system is designed to last for years with minimal maintenance. Combined with our 10-year workmanship guarantee, you can be confident in the long-term durability of your investment.
Yes, the HUP! system offers extensive customisation to seamlessly match your existing property. We offer a wide range of external finishes including brick slips to replicate your home's original brickwork, modern coloured renders, premium timber cladding, and durable fibre cement boards. Our design team will help you choose the perfect finish to complement your home's character.
Yes, significantly. HUP! extensions achieve superior U-values compared to standard brick-and-block construction because the SIPs panels incorporate high-performance insulation as standard. This means lower heating bills, a more comfortable living environment, and improved energy efficiency ratings — a major advantage as energy costs continue to rise across East Anglia.
