Garage conversion plans in Lambeth

Conservation areas and Article 4 directions in Lambeth

With 64 conservation areas, a great deal of the borough carries extra control, and the planning data service lists 12 Article 4 directions covering 223 mapped areas. Historic England adds 953 listed entries. A garage on any of these streets may need an application if its front changes.

A separate Article 4 direction removes the right to turn a family house into a small HMO, which is the route some owners take with a converted garage plus a spare room. If your plan is a self-contained letting, tell us at the start. It changes the planning route, the fire design and the licensing, and it is better settled before drawings are produced.

We also note the 339 tree preservation orders recorded in the borough. Street trees and garden trees close to a drive are worth locating before drainage is drawn.

Which route a Lambeth garage conversion takes

National law begins in your favour: Works affecting only the interior, or not materially affecting external appearance, are not development. Where the garage door stays and only the inside changes, no application may be needed. If you convert it for use as a separate dwelling, that is a material change of use and needs permission whatever the outside looks like.

For a clear internal case we apply for a lawful development certificate in Lambeth. For anything that changes a protected frontage, the application goes in with our planning drawings in Lambeth, and if the work is more like a self-contained unit we would point you to flat conversion drawings in Lambeth.

Our free constraints check includes the original planning decision for the house. Some estates were approved on the basis that the garages stay available, and that condition is easier to deal with early.

How Lambeth has decided householder applications

In its last twelve published months Lambeth granted 83.4 per cent of householder applications and decided 93.4 per cent within eight weeks or an agreed extension. These are borough-wide figures for every household project. They tell you something about how busy the process is, and nothing about a given garage.

A terraced home here has averaged £796,865 in the latest Land Registry data, which makes a usable extra room valuable, and also makes the cost of a refusal larger than the cost of careful drawings.

Escape, ventilation and the price of the set

A bedroom in a former garage needs a means of escape. The Approved Document B test is: Escape window: unobstructed openable area at least 0.33 m², at least 450 mm high and 450 mm wide, bottom of opening no more than 1100 mm above floor. If the only external wall faces the street, the escape window and the conservation-area frontage have to be designed together, which is why we draw them as one elevation.

Fresh air matters more once the old garage door is sealed. Approved Document F sets extract rates for any wet room you add: Intermittent extract: kitchen 30 l/s with cooker hood (60 l/s otherwise), utility 30 l/s, bathroom 15 l/s, WC 6 l/s.

The fee for the set is £695, VAT included, fixed before we begin, with a second chartered technologist checking each sheet. If the council asks for amendments we redraw free of charge. The detail that building control approves is in our building regulations drawings in Lambeth.
