This example is a wonderful Grade II listed property – the original building is quintessential timber framed farmhouse, but the extension stands out with its flat roof and lots of glass. But it still works. Why? Because the extension is bold while remaining sensitive to its surroundings.
One of the big lessons here is the use of materials. The architect has utilised ragstone common to the local area, and cherry veneered walls complement the natural materials of the old house. The open plan layout works because it is punctuated by a generous use of natural materials throughout.
You can be bolder and starker and still make your addition work well. This sharp, angular glass extension on a 1950’s commuter house in Buckinghamshire thrusts itself into the garden. Glass is a wonderful material. It’s pure and elegant and there's no better for letting in bags of natural light.
However, glass also lets out heat, so if you are planning to use lots of it you need to take into account the orientation. Build it south facing and go for double or triple glazing and make sure to go to town when fitting insulation. Underfloor heating will also help to counterbalance some inefficiencies of using glass.
A glass extension doesn’t need to be square or huge. One of the best is this small but perfectly formed addition to a Grade II listed building. The architects have been really imaginative and made glass, a potentially hard and cold material, into something light and lyrical. This award winning extension links a Georgian house to its garden, and is a refreshing departure from the predictable glass box.
Its delicate design echoes the raised wings of a bird about to take flight, a perfect gateway between house and garden. This exemplifies the golden rule when it comes to extending an older property – be as bold as you like but always take your lead from the local surroundings.
