Summary
The owner wants to add two new homes to an existing building on Treport Street in Wandsworth. This would involve raising the roof at the back and building upward on top of the existing two-storey rear section, adding roof terraces and new roof lights. The building is a mid-terrace property built between 1900 and 1929, in a busy part of south-west London. Properties are closely packed to the north and west, with Swaffield Primary School a couple of minutes' walk away and the River Wandle about two minutes' walk away to the east. Around 173 nearby homes and businesses have a clear line of sight to the site. The terraces and new upper floor could be visible from properties to the east, north and north-east, and new opaque screens are proposed to reduce overlooking from the roof terraces.
