  37 Flask Walk London NW3 1HH

  The proposal is for three minor works to the rear facade of the existing listed cottage. It replaces the previously permitted winter garden in its entirety. (See PP-11327012) Proposed works include: 1. to remove existing cement render to rear facade that has caused damp to be trapped in the bricks behind it and replace with a breathable lime render 2. to replace the existing partially glazed timber stable door with a new fully glazed timber back door 3. to install a painted timber shed on existing flags in previously permitted location of proposed bathroom 4. to install an additional new heritage rainwater downpipe to augment the existing downpipe which has insufficient capacity and is causing damp in the walls
