Planning and building regulation drawings in Ealing Broadway (W5)
The ground north of the Broadway rises, and that hill is where much of W5's larger housing sits: late-Victorian and Edwardian villas and semi-detached houses, many on generous plots. Closer to the station the stock shifts to Edwardian mansion flats and family houses that have been divided up. The district's roads include Mount Park Road, Castlebar Road, The Mall, Grange Road and Uxbridge Road. Those two kinds of property raise different questions. A villa owner may be weighing a side or rear extension, a loft, or a rework of a big house, while a flat owner has no householder permitted development rights and deals with lease questions and party walls alongside any design.

Three conservation areas touch the district. Mount Park takes in the higher ground north of the Broadway, with close control of rooflines, materials and front elevations, while Ealing Common and Ealing Green follow the southern and eastern edges. Their boundaries overlap, so it is easy to assume an address is in one area when it falls in another, and that changes what the council will accept on the roof and the street side.
On the larger plots, side and rear additions are assessed against neighbouring garden and building lines, so the houses either side shape the design alongside the rules. Mature street trees on several of the villa roads carry Tree Preservation Orders, which can influence where an extension can sit. Ealing's borough-wide HMO direction applies here as it does across the borough, and is relevant if a big house is being considered for shared lets. We map these layers for the specific property before drawing begins.
Planning in Ealing Broadway: what to know before you apply
For W5 the first task is working out which conservation area a property sits in and what that means for the design. In the conservation areas, Ealing controls rooflines, materials and front elevations closely. A protected tree is checked early because it can move a footprint. Converting a house to a small HMO, shared by three to six unrelated people, is caught by the borough-wide Article 4 direction, which is separate from householder extension work. Flats and subdivided houses add questions of freeholder consent and party walls that sit outside planning. We establish all of this before drawing.
