What we measure and what you receive
We measure the internal rooms and external walls on site and return plans showing the building as it is. Nothing is estimated from old drawings.
The service sits on our measured building survey page, with fees on the pricing page.
Hounslow's speed and workload
Hounslow decided 97% of householder applications within eight weeks, once prior approvals are excluded (our analysis of MHCLG planning application statistics, table PS2, released 24 September 2026).
The same table gives 689 householder decisions for the four quarters to June 2026, prior approvals included.
National planning practice guidance says drawings must use an identified scale and plans must show north, with location plans typically at 1:1250 or 1:2500.
Article 4 entries near TW3
Our analysis of the MHCLG Planning Data Platform article 4 direction dataset (entity API, retrieved 15 October 2026) found 2 live register rows near the TW3 outcode centroid. The register is incomplete, so this is a lower bound and not proof that your street is clear.
An article 4 direction can remove permitted development rights, so ask Hounslow Council before you assume a project needs no application. If you plan a certificate, see our lawful development certificate drawings.
Conservation areas across the borough
The national register holds 43 conservation-area entries for Hounslow (our analysis of MHCLG Planning Data Platform datasets, bulk snapshot retrieved 14 August 2026). That count is for the whole borough, not TW3 alone, so find your street on Hounslow's conservation area map.
Scale, north and location plans
National planning practice guidance says drawings must use an identified scale and plans must show north, with location plans typically at 1:1250 or 1:2500. A measured survey gives you the dimensions to meet that without guesswork.
When the survey is complete, planning drawings are the next step for most extension and loft projects.
