Sharpline Construction Ltd has been building and renovating homes across London since 2013. We handle house extensions, loft conversions, full and partial refurbishments, kitchen and bathroom fitting, structural alterations and bespoke joinery - one contractor managing the whole job from first site visit to final snagging.

We're based in East London and work across all London boroughs, from family homes to large commercial fit-outs. Projects have ranged from bathroom refurbishments to landmark hospitality work, including a guest sauna at Shangri-La at The Shard and decoration, plumbing and electrical works at Le Cordon Bleu London.

Every project starts with a free site visit and an itemised written quote, so you know exactly what's included before work begins. We're fully insured, CSCS carded, and hold SMSTS site supervision qualifications in-house: the same team, the same standards, on every job.
