Barnet / Harrow · HA8, HA7
Extensions, loft and basement conversions, renovations and new homes in Edgware & Stanmore, designed and built by Milkov & Son from our base in Hendon.
Edgware and Stanmore are a short drive up the A5 and A41 from our Hendon office — long roads of 1930s semis and detached houses, the larger houses of Canons Park and Stanmore Hill, and the country-edge plots towards Bushey Heath. The briefs are about family space: bigger kitchens, extra bedrooms, and increasingly the replacement of tired houses on good plots.
Edgware (HA8, in Barnet and Harrow) is predominantly 1930s — semi-detached and detached houses with bays and hipped roofs, plus Edgwarebury's larger houses near the green belt. Stanmore (HA7, Harrow) ranges from 1930s semis around the Broadway to substantial detached houses on Stanmore Hill, Old Church Lane and the private roads, with the Stanmore Hill, Little Common and Old Church Lane conservation areas and Canons Park's 1920s–30s garden-suburb houses.
Edgware is split between the London Borough of Barnet (east of the Edgware Road, broadly) and Harrow; Stanmore is Harrow. Outside conservation areas, permitted development applies to houses in the usual way and rear extensions and rear dormers are routine. Harrow's conservation areas on Stanmore Hill, Little Common and Old Church Lane, and Canons Park's Article 4 direction, bring external alterations under planning control. Harrow publishes a residential design guide with expectations for side extensions (set back, subordinate, 1 m to the boundary at first floor) that we design to. Green-belt land at Stanmore Common and Edgwarebury limits extensions to existing buildings.
Rear kitchen extensions and double-storey side extensions on 1930s semis; hip-to-gable lofts; whole-house renovations of large Stanmore houses; and replacement dwellings on the bigger plots of Stanmore Hill and Canons Park.
Wide roads and driveways make logistics straightforward across most of Edgware and Stanmore. The clay is shrinkable and the large gardens have mature trees, so foundation depths are checked early. Party wall notices apply to semis. The Jubilee line at Stanmore and Canons Park keeps client site visits simple.
Planning authority: London Borough of Harrow. Conservation-area boundaries and Article 4 directions change; we confirm the position for your address before advising.
Both. Broadly, east of the Edgware Road is Barnet and west is Harrow. We confirm the planning authority from the address before advising.
Usually with a householder application to Harrow. The council expects side extensions to be set back from the front, subordinate in height, and to keep about 1 m to the boundary at first floor to avoid a terracing effect.
Yes, including the conservation areas and Article 4 streets where external changes need planning permission.

Rear, side return, wraparound, double storey and kitchen extensions — designed, approved and built by one team.

Dormer, hip-to-gable, L-shaped and mansard conversions that add a bedroom and bathroom without touching the garden.

Whole-house refurbishments and reconfigurations of 1930s, Edwardian and Victorian homes, managed as one project.

Feasibility, design, approvals and construction under one contract, with one person accountable for the result.
