Housebuilding in this country is often framed as a choice between on-site masonry construction and off-site, factory-built timber frame. But the reality is a little more complex. There are systems which, while nominally one or the other, don’t much resemble either of the mainstream formats.

Insulated concrete formwork (ICF) is one such system. Because it uses large amounts of concrete, it’s very much in the territory of masonry construction and it’s also very much an example of on-site building.

Mark is the author of the ever-popular Housebuilder’s Bible and an experienced builder. The Housebuilder’s Bible is the go-to hardback for self builders; originally published in 1994, it is updated every two years with up-to-date build costs and information on planning and building regulations, and is currently in its 14th reiteration.

He has written for publications such as Homebuilding & Renovating for over three decades. An experienced self builder, his latest self build, a contemporary eco home built to Passivhaus principles, was created on a tight urban brownfield plot.
