Bellingham

Bellingham is a district in south east London, in the London Borough of Lewisham. Its neighbouring districts are Catford, Sydenham and Downham. The Ravensbourne River runs through the middle of Bellingham, and to the east and west it is bordered by railway lines running south from Catford.

The true name Bellingham means ‘the water-meadow owned by Beora’s people’, and was the real name of the medieval manor in the area. The name was preserved by the farm in the region, Bellingham Railway Station and the Bellingham Estate. Additional historical names have already been preserved by the road names of the estate, which are linked with King Alfred, who was thought to have been god, the father of the manor of Lewisham, and were taken from the true names of mills, houses and fields in the area.

Bellingham was mainly farmland until the Bellingham Estate was built, mostly between 1920 and 1923. London City Council built about 2600 houses and flats during this time. Bellingham Estate was one of many large estates built by London City Council following the First World War to assist with slum clearance and alleviate overcrowding. As there was plenty of land available most of the dwellings constructed were two-story houses, and there was lots of green, open space.

Today, Bellingham is a localised city centre. Its high street is Randlesdown Road, which has a supermarket, a gym, hairdressers and multiple restaurants and food outlets. It has a sixth form college also, and a church and a library. Bellingham boasts many well-known former and present residents, including the singer/song-writer Kate Bush, the previous Labour Prime Minister James Callaghan, and the footballer Ian Wright.

how big can my house extension be?

The holy grail of home extensions is basically the need for additional space for living as well as leisure. However, before commencing your home extension project, you’d probably want to know just how big your new building can be. In this article, you’ll find the answer to this question which is also frequently asked by many other home or property owners in the UK.

Besides your budget, there are two other major influencing factors that can determine just how much extra room that can be added. These factors include whether you wish to carry out the extension project under Permitted Development rights which is usually for a smaller project or you’d prefer to opt for a larger project which is covered by Planning Permission.

Apart from the limitations in the size of an extension under Permitted Development, the extensions are also a lot more affordable and consumes less time when compared to the extensions under planning permission. So what exactly is the size limit for an extension under Permitted Development and the ones under Planning Permission?

For a single storey extension, the maximum size that can be constructed without having to submit an application for Planning Permission includes:

• An extension should have a maximum length of 6m, if you reside in a terraced home or a semi-detached property.

• Extensions for detached properties can have a maximum length of 8m.

• The extension built must not go beyond half your garden’s area.

• The extension should have a maximum height of 4 metres, but in the event whereby the extension is situated within 2 metres of the boundary of your property, it should not exceed a height of 3 metres.

• The extension should not be higher than the highest part of the existing house’s roof.
