Princess Park Lane

This is a project for a one-storey rear extension for two-storey semi – detached house in Hayes, London.

This is a typical 6 meters one storey rear extension. The ground floor is formed in 150 mm thick reinforced concrete ground bearing slab reinforced with one layer of A252 mesh in top throughout.

The foundations are 600 mm wide eccentric and concentric mass concrete trench footings with minimum depth of 1000 mm from ground level.

The roof is formed in flat roof joists bearing on timber plate, steel beam B1 and a cavity wall.

In this project, the challenge was building over the main sewer pipe. For this purpose we have designed bridge detail for both sides of the extension. The structural plans were submitted to Thames Water and the building over the sewer pipe was approved.  

Also, the structural drawings and calculations were submitted and approved by Building Control.

The building works were finished in approximately three months time.
