Planning committee

Decided by Greenwich Local Planning Committee on 27 Jan 2026. The council has not yet issued its decision notice.

Refused unanimously

As officers recommended.

Officers advised refusal because the extension would harm the locally listed building, terrace and conservation area through its design and scale.
The applicants said the smaller extension would support their growing family without harming neighbours, the conservation area or public views.
Members voted unanimously to refuse permission because of the extension’s height, scale, design and position.

Site constraints 10

Blackheath conservation area

Demolition needs planning permission and permitted development is restricted.

The council must give weight to preserving or enhancing the area's character and appearance. Not every council has published its boundaries as open data.

In flood zones plus climate change

Inside the extent flood zones 2 and 3 could reach with climate change: the Central allowance for the 2080s on rivers, the Upper End allowance for sea level rise to 2125. From the sea. Defences are not counted.

The Environment Agency flood map for planning. Councils use it to decide when a flood risk assessment and the sequential test are needed. It is indicative and does not show whether a particular property will flood.

National infrastructure project: Thames Tideway Tunnel

The site is inside the project boundary. Waste water treatment, decided. The project page says whether consent was granted. Also within 2 km: London Strategic Heat Main Project (at pre-application, 492 m).

Nationally significant infrastructure projects (power stations, electricity lines, pipelines, major roads and railways, harbours, airports and reservoirs) are consented by a Secretary of State under the Planning Act 2008, after an examination by the Planning Inspectorate, rather than by the council. The boundary is the one the Inspectorate consults on and can change as the scheme does. Projects are shown within 2 km of the site.

Air quality management area: Greenwich AQMA

The council has declared the area as failing an air quality objective.

Schemes that add traffic, parking or combustion plant are assessed against the area's action plan and may need an air quality assessment.
