A few months ago I’ve presented an interesting way to add a room to your apartment. Some people said that this is a crazy idea, but others found it interesting. Today I would like to present an interesting extension to a house located in the city of Hertfordshire north of London, England. In this project ( Harpenden House ) made by Crawford Partnership, the existing house was significantly extended adding an extension to the side in the style of the original building, a new basement level below ground and to the rear, a dramatic glass extension. The glass extension is an all-glass structure using toughened glass beams connected to glass fin columns. Even the doors have been constructed to be frameless using spider hinge joints to hand them off the glass wall panels. The “glass box” ties together newly created open plan living spaces within the existing house and the new side extension whilst also providing a huge new living/dining are integrating with the garden beyond. – Via
