Project requirements

Long Meadow, a unique development of 114 apartments and houses, was built by Czero with the assistance of Barnes Construction and Khoury Architects. It used the very latest sustainable building techniques, whilst retaining the principles of affordability. The development was built to comply with level four of the Code for Sustainable Homes, so it was important that the properties had a low impact on the environment, as well as being cost and energy efficient. Czero approached JELD-WEN because they wanted to use sustainable windows that were produced in the UK.


Stormsure triple glazed fully finished windows with a U value of 1.2W/m²K, which met the project’s requirements perfectly, along with DreamVu™ timber doorsets that also deliver very low U values.


Highly energy-efficient hemcrete walls, combined with Jeld-Wen’s triple-glazed timber windows, mean the Long Meadow homes offer the very best thermal performance, are affordable to heat and have a very low carbon footprint. The properties were designed to complement the local style, which was enhanced by the aesthetics of the fully finished windows.

Client Feedback

Robert Pearson, Czero director, said: “This very exciting development shows how, through careful selection of green technologies, such as windows and doors with very low U values, new homes can offer a much higher level of energy efficiency. We wanted to use timber windows for their aesthetics and the fact that they are made from a truly sustainable material, which fitted well with the ethos of these homes. The result is homes that are attractive to look at, affordable to run and have the very best environmental credentials. We expect these homes to provide a benchmark for future sustainable construction.”
