Precast is a method of building construction. It meant the building construction method is a pre-process, what we so called "prefabrication". From the factory site and move all the pieces to the building site. Now prefabrication technology has been upgraded to "three-dimensional level", by the inner and outer walls, floor tiles and a bathtub etc., made it in the factory, after transport to the construction site and assembly.
In terms of sustainable, construction industry is considered producing a lot of pollution. And off-site construction can benefits more eco-friendly. Precast everything at the factory can effectively reduce material consumption, especially precast the interior parts as it always produce a lot of construction waste. Besides, other than the waste, precast construction can also reduce the sound and air pollution during the construction.
Oxley Woods is one of the sustainable building example in UK. For that reason, the chose precast technology to built all those 145 houses. "each house to be quickly and economically erected while maintaining build quality "As you can see from the photos, the building method is like a "lego", put everything piece by piece. Yet, they even just required less amount of people and skills to construct everything.
