Why measure before you design
A homeowner in Colliers Wood who wants a loft or an extension needs plans of the house as it is. Estimating from a photograph or an old estate agent's floor plan leads to drawings that do not close up at the council.
The survey produces existing plans drawn to a stated scale with north shown, which is what planning guidance asks of plans and drawings. The proposed design is then drawn over them.
Location plans for the same address
The location plan is the companion to the survey. National guidance says its scale should typically be 1:1250 or 1:2500, so it shows the wider street while the survey shows the house itself.
Merton decided 270 certificates of lawful development in eight quarters.
Merton's householder record
Over the latest four quarters Merton decided 759 householder applications and granted 93% of them.
On timing, 75% of householder decisions were made within eight weeks, which leaves a quarter that took longer. If you have a firm build date, allow for that.
Appeals and conservation areas
Merton has 108 householder appeals decided in the Planning Inspectorate casework database, with 36% allowed. The national planning data lists 28 live conservation-area entries, which is worth checking against your street.
Lawful development certificates and price
Merton decided 270 certificates of lawful development in eight quarters. A measured survey is useful evidence for one. The survey starts at £200 with no VAT to add, listed on the pricing page.
