Completion
To demonstrate the Porotherm walling system in action, this project was filmed by a time-lapse camera, providing a quick-fire visual perspective of how the system helped reduce the overall build time. The video can be viewed on the Wienerberger website: www.wienerberger.co.uk/walls/clay-blocks/using-porotherm/videos
Clearview Homes specified Porotherm to speed up construction of a new development in the centre of South Harrow.
The system was used for the internal structure, going up one floor per eight days and making the building ready for roof installation within 10 weeks. Once this internal structure was erected, external facing bricks were applied and internal fix began at the same time – which cut a 15-month build to around 12 months in total. Clearview Homes’ technical manager, Richard Drury, said speed of construction was vital for housebuilders during the recession. He said: “This highly-anticipated development is in the centre of town where there is high demand for new, good quality housing. We believe there will be a lot of interest from buyers and so were keen to get on with construction as soon as possible.

“Porotherm offered us the ability to complete the development three months earlier than we would normally have finished if we used another method of construction. This obviously had implications for the sales cycle as it allowed us to release the properties onto
the market much sooner than usual.” This was the second time Clearview Homes used Porotherm for the structural internal cavity walls to increase construction speed. The developer completed a development of 12 houses at Hadley Gate in Alexandra Avenue, also in South Harrow, and shaved two months off the build programme by utilising the system. “The lessons we learned from the first project are being brought to bear on the second. Pre-planning and organisation are vital in order to make the best use of the system and really benefit from the speed. It exceeded our expectations at Hadley Gate and was the obvious choice for the new scheme,” added Drury.
