£475,000 Adding extensions to historic buildings isn't straightforward, but the right idea perfectly executed can create something really quite special. Here, the idea was not to detract from the 14th century hall so the extension is a glass box that disappears into the surroundings. This two bedroom hall would cost you £475,000.
£300,000 Less grand and less money, this award winning barn conversion in Cambridgeshire is linked to the contemporary extension via a double height glass passage. The wood cladding complements the original brick walls of the barn while the white render is unashamedly modern. Only 50 miles from London, a property like this would set you back around £300,000.
£4,350,000 This extension in London is a good example of how a contemporary design can transform any building. This traditional Edwardian house has been enhanced by a very cutting edge double height glass and steel extension. With seven bedrooms, a stunning garden and plenty of living space there's an inevitably huge price tag - £4.35million.
£1,000,000 The reason this triple height modern extension in Calverley works so well is because it cleverly mimics the original lines and size of the existing barn. But the vast use of glass places the extension firmly in the 21st century. With five bedrooms, a spectacular drawing room and a swimming pool you’d be surprised at the price for a property this size - just under £1million.
£3,500,000 How about this Grade II listed building, a former stable in Kent. The timber-clad extension was added a few years ago to accommodate guests and a swimming pool. The entire place is kitted out with the latest environmentally friendly stuff, including insulated walls and floors, rainwater recycling and LED and low energy lighting. The pool is heated by solar panels too.
