Reference projects
The trio of family houses is set in historic Prague, formerly an independent village. To the east of the new building, there is a row of houses of the original tissue that strictly respects the street boundary line. To the west, the plot is adjacent to a sloping road leading to a former cemetery at the historic Hvězda preserve.
The simple white volume which strictly follows the street boundary contains two of the houses, its length along the street reflecting the typical plot width of the old village, while the end section clad in grey aluminium turns away to reflect the neighbour, and its exceptional position means that it contains a larger home of the client himself. Although the volumes and materials are referring to traditional architecture, they are interpreted as a simple and modest homogeneous mass with minimal detailing.
Broadway Market is a vibrant area, lined with two and three storey properties with a variety of commercial uses, and on Saturdays the street is pedestrianised for a lively market. Parallel to the main street, Broadway Market Mews is largely occupied by local businesses, shops and a strong artist’s community that has been in the area for a couple of decades.
The retained brick structure acts as a plinth to a new lightweight timber frame extension, with exposed glulam spruce beams to the interior, and clad in light grey standing seam metal to reflect the changing light. The approach was to generate a shape which would maximise daylight penetration and minimize the sense of enclosure to the surrounding properties, softening the impact of development.
