Peckham · Dulwich · Bermondsey · Camberwell
Southwark runs from Bermondsey near the river down through Camberwell and Peckham to Dulwich. Terraced Victorian houses are common, alongside mansion blocks and larger semi-detached homes further south. Side-return extensions, loft conversions and internal knock-throughs are frequent projects, and each can involve work to a party wall or new foundations near a neighbour. We help Building Owners and Adjoining Owners understand the procedure and reach an agreed outcome.
Brockley · Forest Hill · Catford · New Cross
In South East London's Lewisham, neighbourhoods such as Brockley, Forest Hill, Catford and New Cross include many Victorian and Edwardian terraces and converted houses. Owners commonly add rear extensions or convert lofts, while flat conversions can mean several Adjoining Owners for one project. We confirm who must be served, prepare the right Notices and, where a dispute arises, prepare an Award that records the works and protects both properties.
Greenwich · Blackheath · Eltham · Charlton
Greenwich, Blackheath, Eltham and Charlton offer a wide range of homes, from period terraces near the town centre to interwar semi-detached houses further out. Rear and side extensions, loft conversions and structural alterations are regular projects across the borough. Where neighbouring foundations are close, excavation for an extension can fall within the Act. We assess the plans and explain clearly whether Notices are needed and what happens next.
Bromley · Beckenham · Chislehurst · Orpington
Bromley is one of London's largest boroughs, taking in Bromley town, Beckenham, Chislehurst and Orpington. Semi-detached and detached houses with good-sized plots are common, and owners often extend to the side and rear. Even detached homes can be affected where new foundations are dug close to a neighbouring building. We act for Building Owners and Adjoining Owners across the borough and agree a fixed fee from the outset.
Brixton · Herne Hill · Streatham · West Norwood
Lambeth's Brixton, Herne Hill and Streatham neighbourhoods feature long Victorian terraces and many houses converted into flats. Loft conversions, rear extensions and internal structural changes frequently involve shared walls, and party floors between flats can also bring the Act into play. We identify all owners affected, including those in converted buildings, serve the correct Notices and keep the process clear and well organised for everyone involved.
Croydon · South Norwood · Purley · Coulsdon
From South Norwood to Croydon town and south towards Purley and Coulsdon, the borough has a broad mix of terraced, semi-detached and detached homes. Rear extensions, side extensions and loft conversions are common, and on sloping sites deeper foundations may be needed close to neighbouring buildings. We review your drawings to confirm which parts of the Act apply, then handle the Notices and any Award with one surveyor throughout.
