New Ra Concept Offers Hassle-Free Building

A new concept in quick and efficient masonry construction, which is set to revolutionise the UK housebuilding industry, has been introduced by H+H Celcon.

Known as the Rå House (pronounced ‘raw’), it utilises teams of Expert Installers who work quickly and efficiently to complete the weatherproof, high quality masonry shell of a house.

The concept uses Celcon aircrete blocks with the Thin-Joint system, proprietary intermediate floors and roofs with options for Celcon Foundation blocks, and the Celcon Flooring System at ground floor.

Comments Ian Exall, marketing director of H+H Celcon: “The Rå House has been developed in response to the growing demand for Modern Methods of Construction. By offering a combined package of build and materials, builders can benefit from some of the most innovative materials and processes available today without any hassle – because it’s all done for them.”

The concept avoids delays and logistical problems in coordinating different tradesmen. Well-practiced teams of Expert Installers are able to build the shell in extra-quick time and, because they are experienced in the techniques, ensure a superior build quality. Once completed, the Rå House is ready to hand over for external finishing - at the same time as first fix trades are working inside. The concept offers similar build speed to timber frame construction without the lead-time required for manufacture, and offers greater design flexibility.

Continues Exall: “The scheme is a simple, cost effective solution for private or social housing providers and quickly produces a robust aircrete masonry shell with excellent thermal and acoustic insulation properties.”

H+H Celcon is developing a network of Rå House Expert Installers with all the necessary skills covering blocklaying, H+H Celcon’s Thin-Joint System, floor installation and roof construction. The Housing Corporation and English Partnerships recognise H+H Celcon’s Thin-Joint System as a Modern Method of Construction (MMC).

Using aircrete blockwork for foundations, external walls, ground floors and partitions boosts a scheme’s chances of achieving ‘A’ ratings (under the BRE’s Green Guide to Specification) and Good, Very Good and Excellent passes (under the BRE’s EcoHomes Assessment scheme).
