Planning and building regulation drawings in Hendon (NW4)
Hendon is really two places that share a postcode. At the centre is a linear historic village around the medieval parish church of St Mary, and most of its buildings are homes. Around it, the wider NW4 suburb is made up of Victorian and interwar houses, where a homeowner might weigh up a bigger kitchen, a loft bedroom or a rear extension. Streets in the district include Church Road, Church End, Greyhound Hill and Parson Street. The two halves need different handling, and the first job on any Hendon address is to work out which one you are in.

Away from the village, Barnet generally leaves its semi-detached suburban houses their permitted development rights for rear extensions and loft conversions, so rear extensions and lofts there can often proceed as permitted development, subject to the limits, rather than through a full application. Building-regulation drawings still matter just as much, because structure, insulation and fire safety are checked whatever the planning route turns out to be.
Close to the church the picture changes. The Hendon Church End conservation area, designated in 1983, protects the low-rise historic setting of the church, and several buildings nearby are listed or held by Middlesex University. The Church End ridge gives long views across the borough, so a roof addition here is judged for how it reads on the skyline as well as from the street. We start by checking where your property sits against that boundary and against any listed neighbours, then decide whether the drawings need to support a householder application or a lighter route.
Planning in Hendon: what to know before you apply
Barnet assesses householder work against its surroundings, and in NW4 the Hendon Church End conservation area adds a layer of its own. No Article 4 direction is confirmed for the area, so no extra rights are withdrawn by direction. Conservation-area status itself still takes roof enlargements, side extensions and rear extensions of more than one storey out of permitted development, and the designation shapes what officers will accept next to the church and its listed buildings, particularly for anything that changes a roofline or a front elevation. Outside the conservation area, Barnet's semi-detached houses usually keep their rights for rear and loft work, which makes the route simpler. Where a property faces or adjoins listed buildings, we check the setting early so the drawings answer the questions a case officer is likely to raise.
