Southwark

The London Borough of Southwark in south London, England forms a part of Inner London and is connected by bridges across the River Thames to the City of London. It was established in 1965 when 3 smaller sized council places amalgamated under the London Government Act 1963. This integrated the former area of the Metropolitan Borough of Southwark, the Metropolitan Borough of Camberwell, as well as the Metropolitan Borough of Bermondsey. It's controlled by Southwark London Borough Council.

The borough covers an overall area of roughly 11.14 square miles. To the south are the London Boroughs of Bromley and Croydon. As outlined by population estimates made during 2014, Southwark includes a permanent population of about 302538 people.

The borough is residence to many cultural, historical and notable attractions. The Shard, Tate Modern, Shakespeare's Globe Theatre, and Borough Market which are the biggest of the venues in Southwark to draw domestic and international tourism. Dulwich houses the Dulwich Picture Gallery plus the Imperial War Museum in Elephant and Castle.

FAQs

do you need planning permission for a loft conversion?

Typically, loft conversions do not require planning permission except in certain situations. They’re usually covered under what’s known as Permitted Development. Certain building works like loft conversion, rear extension and conservatories are granted planning permission by local authorities. Permitted Development, however, gives you a free range to improve your home without having any issues from the councils or regulations. Before your planned loft conversion can be covered under Permitted Development, there are some certain criteria that must be met. This criteria includes the following:

✓ The extension must not go beyond the existing slope of the roof at the front of the house.

✓ The loft space converted must not go beyond 40 cubic metres in a terraced house.

✓ The roof’s height must not be increased by the extension.

✓ The loft space converted must not reach beyond 50 cubic metres in a detached or semi detached house.

✓ The plan for the extension mustn’t involve structures like balconies, verandas or anything other structures of this nature.

✓ The roof extension should be positioned as far back as possible or at least 20cm from the existing eaves.

✓ The side that faces the window openings should be at least 1.7m beyond the floor and the windows should also be obscured.

✓ The roof extension must not overhang the existing roof or wall of the house.

✓ The materials that are to be used must be similar or the same to the materials that has already been used on the house’s exterior.

However, you should bear in mind that there are some properties that are exempt from Permitted Development. Examples of these type of properties include conservation areas, Areas Of Outstanding Natural Beauty and World Heritage sites. Permitted Development does not also provide coverage for listed buildings.

How long will a loft conversion take?

It depends on the style and size of the conversion, but in general, a loft conversion will take between 1-2 months. A loft conversion is a substantial building project, and plans will need to be drawn up. This may add to the time it takes to complete your loft conversion.

What kinds of loft conversion are there?

There’s a huge range of different types of loft conversions. The most common are dormer and skylight or Velux conversions. There are also hip to gable and mansard conversions. The type of loft conversion that’s most suitable for your property will depend on the style of roof and the size of your loft.

Will I need planning permission to convert my loft?

Planning permission is not normally needed for a loft conversion as they are covered by permitted development rights. A conversion company will tell you if you do and help you with this. For more information, see our article about planning permission.
