Read from the description, not a valuation. How we read the register

Still open. Anyone can comment while the consultation period runs, and comments go to the council rather than to us.

Proposal

Proposal for an existing 1960's ground floor flat. To upgrade the flat to meet modern safety, energy and comfort standards. The additional internal floor area is 29m2. The rear is proposed to extend 4m and the side, 1.8m. This has resulted in the improved the volume to surface area ratio which reduces heat loss rate. This has also improved the quality of the property by the addition of a third bedroom as well as the efficient use of space to introduce one new bathroom and a living room kitchen arrangement where previously the rooms were small and closed off. A patio will extend into the garden and a new fence will replace the existing which is in poor condition, on the side return. To ensure environmental alignment, the proposal considers a whole house approach by introducing external wall insulation to existing walls to reduce energy consumption of the property and to work efficiently with an air source heat pump and underfloor heating. The garden will be planted with plants local to the UK. No changes have been made to communal areas and the use remains as residential.

What happens while it is decided

The process from here

This application is with Southwark for determination. The council publicises it, consults neighbours and technical bodies where required, and weighs the responses against local and national planning policy.

The statutory target is eight weeks for most applications and thirteen for major development, though extensions of time are common. Comments carry most weight while the case is undecided, so check the council portal for the deadline if you want to respond.

About full applications applications

How this application type works

A full application seeks permission for a complete, detailed proposal in one go: siting, design, access and landscaping are all fixed at this stage. It is the standard route for new buildings, conversions and changes of use. The statutory target is eight weeks for smaller schemes and thirteen weeks for major development, though complex cases often take longer by agreement.
