Builders in Newham
We've been based in Newham since the company started in 2013. Our registered office is in East Ham, most of our team lives locally, and a good share of the work we do never leaves the borough — which means when you call us for a site visit, we're usually there the same week rather than the week after.
Sharp Line Construction covers the whole of Newham: East Ham, West Ham, Forest Gate, Manor Park, Plaistow, Upton Park, Canning Town, Custom House, Beckton, Silvertown, the Royal Docks and Stratford. Postcodes E6, E7, E12, E13, E15, E16 and E20

Newham's housing stock, and what it means for your project
Most of Newham's residential streets are Victorian and Edwardian terraces, particularly through East Ham, Forest Gate, Manor Park and Plaistow, with pockets of 1930s semis and a large amount of new-build apartment stock around Stratford and the Royal Docks.
Terraced houses respond well to two things — a side return infill that widens the ground floor, and a loft conversion that adds a fourth bedroom without touching the footprint. Both are usually achievable within permitted development limits, though the party wall process with your neighbours needs starting early.
1930s semis are the easiest hip-to-gable candidates in the borough. Extending the sloping hip into a vertical gable end typically buys enough headroom for a full bedroom and ensuite where a straight Velux conversion wouldn't work.
New-build flats around Stratford and the Royal Docks are a different job entirely: no structural work, but tight building management rules, restricted working hours, lift bookings and shared-service protections. We've worked to those constraints before and we price them properly rather than discovering them halfway through.
Planning and building control in Newham
Planning applications and building control for Newham go through Newham Council at newham.gov.uk. A few borough-specific points worth knowing before you commit to a design:
Newham operates Article 4 directions in parts of the borough, which remove certain permitted development rights. Whether one applies to your street affects what you can build without a full application — worth checking before you pay for drawings.
Newham has several conservation areas, including the Woodgrange Estate in Forest Gate. If you're inside one, permitted development is significantly restricted and materials will be scrutinised.
Building Regulations approval is required for extensions, loft conversions, structural alterations and most electrical and plumbing work, regardless of whether planning permission is needed.
We check all of this at the survey stage and tell you plainly which route your project takes before you spend money on design

Frequently asked questions
Do you only work in Newham?
No — we work across 21 London boroughs, from Kensington and Chelsea through to Bexley. Newham is simply where we're based and where we can respond fastest.
Do I need planning permission for an extension in Newham?
Many rear extensions fall within permitted development, but the limits depend on the property type, how far you're going out, and whether an Article 4 direction or conservation area designation applies to your street. We check this at the survey and tell you which route applies
How much does a loft conversion cost in Newham?
It depends on the conversion type and the specification, and anyone quoting a firm figure before seeing the roof is guessing. A Velux conversion is the cheapest option; a dormer with an ensuite costs substantially more; a mansard is the largest job. We'll give you a written itemised quote after a survey so you can see exactly what drives the number.
Can you work while we're living in the house?
Yes, and most of our residential work is done that way. We protect finished areas, contain dust, and sequence the work so you keep a usable kitchen and bathroom for as long as possible
