Do you need planning permission for a wraparound extension in Barking?
Planning for a wraparound extension in Barking follows the English householder rules.
Side return infills and the side leg of a wraparound are treated as side extensions in England: single-storey, no more than 4 metres high and no wider than half the original house. They are not permitted development in conservation areas, National Parks or National Landscapes, and a joined wraparound often needs a planning application because the side and rear rules apply together.
The Party Wall etc. Act 1996 applies in England: you serve notice two months before work to a shared wall, and one month before digging foundations within 3 metres (or 6 metres for deeper foundations) of a neighbour's building. Neighbours can agree in writing; if they dissent, surveyors agree an award.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
What are homes in Barking like to extend?
Much of Barking is 1920s and 1930s semis and short terraces with longer gardens than inner London, which suit full-width single-storey rear extensions. Parking suspensions, skip licences and controlled hours on residential streets shape the programme more than the build itself.

Including IG11, RM6, RM8, RM9 and RM10, and the surrounding Greater London area.
Can you match the brick or stone on my Barking house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.

Usually 14 to 20 weeks on site, longer than a plain rear extension because of the steelwork.
Is the site visit in Barking free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
