Mansard roof extension & terrace Glenarm Road, Lower Clapton E5


No. 127 Glenarm Road is a 3 storey end of terrace property located near to the junction with Chatsworth Road.

The existing roof is a ‘butterfly/London roof’ with central valley gutter and front parapet typical to the victorian housing stock in the area. Hackney planning have a policy to generally resist mansard roof extensions.

The householder was keen to extend the house upwards to create a master bedroom with ensuite and external terrace.

We set the front of the mansard back to minimise visibility from the street and to provide a small external front roof terrace. The front was fully glazed with sliding doors providing access to the terrace, good views out, and daylight to the new bedroom.

Planning approval was successfully negotiated and approval granted August 2019.
