Residents of Lambeth will most likely be aware that the council’s strict planning laws are in line to be relaxed. This could mean big changes to the amount of space residents will be allowed to add to their homes with a loft conversion.

In previous years, Lambeth Council has enforced a policy that meant planning applications were restricted to small window dormers, with part of the remaining back roof left sloping. This of course meant that Lambeth loft conversions could only use a restricted amount of space, not adding as much space and value to homes as the owners would like. This is especially frustrating on roads that straddle boundaries between councils – your neighbours would be able to maximise their use of space while you could not.

The new regulations – originally planned to be adopted by the council in May 2015, but now more likely to be in effect in September – would allow more styles of loft conversion, as long as they are in-keeping with the style of your home. This means Lambeth homeowners who need more space will not necessarily have to go through the hassle of moving house, but instead can create more space in their current one.


The biggest change to the regulations is that mansard conversions will be allowed in non-conservation areas, as long as they are not visible from the street and slope backwards with a 70° angle. This would also allow neighbouring properties to extend in the same way so that a uniform look would be created across a row of houses.

According to the plans, some leeway may be granted for heritage properties in conservation areas if the conversion is unable to be viewed from the street, although conversions that are not in-keeping with the style of the property will still not be allowed.

These changes are great news for residents of Lambeth who want to add space and value to their home and we’ll keep you posted here when they come into effect.
