Planning Drawings · HA2 North Harrow
Harrow applies standard suburban householder control across HA2, classic 1930s metro-land of bay-fronted semis with few conservation constraints.
If your property sits elsewhere in the borough, the borough-wide page for planning drawings in Harrow covers the same service across every ward.
Planning drawings for North Harrow start by establishing whether your scheme is Permitted Development, needs a Lawful Development Certificate, or full planning from Harrow Council. On HA2's inter-war bay-fronted semis and terraces around north, the recurring questions are roof additions, rear and side-return extensions, and alterations within the local streetscape. We draw existing and proposed plans, elevations and a site location plan to the council's validation checklist for North Harrow, South Harrow, Rayners Lane, West Harrow fringe.
Across North Harrow, South Harrow, Rayners Lane, West Harrow fringe in HA2, the dominant property is inter-war bay-fronted semis and terraces around north harrow and south harrow — classic metro-land. That stock shapes what planning permission drawings looks like here: the right approach for a period terrace differs from a mansion-block flat or a new-build, and Harrow Council judges each on design quality and neighbour impact. We survey the specific North Harrow property, confirm the planning route — Permitted Development, a Lawful Development Certificate, or full planning — and draw a council-ready set tailored to the HA2 streetscape.

Because HA2 is classic 1930s metro-land — bay-fronted semis around North Harrow, South Harrow and Rayners Lane, ideal for rear and side extensions and hip-to-gable loft conversions. With few conservation constraints, much of the work runs on the Permitted Development route, confirmed with a Lawful Development Certificate.
Usually yes — the metro-land semis suit a hip-to-gable plus rear dormer within the 50 cubic metre volume allowance, confirmed by a Lawful Development Certificate. The 1930s roofs generally give good head height. We draw the scheme for Building Control too, which is essential for the new floor and stair.
Often, on the standard semi plots — a wrap-around ground-floor extension or a two-storey side addition, subject to Harrow's design and neighbour-amenity policy on the 45-degree test. We design within those limits and produce the planning and Building Regulations drawings together.
HA2 offers strong metro-land value.
Harrow Council charges its own statutory application fee (currently £548 for a householder planning application, £610 for a full application). We quote the drawings as one fixed price and the free site survey covers every HA2 address.
For a HA2 project across North Harrow, South Harrow, Rayners Lane, West Harrow fringe, expect roughly 3–4 weeks from instruction to submission: week 1 the measured survey, weeks 2–3 the drawings and your revisions, then validation and the statutory determination by Harrow Council (8 weeks for a householder application). We carry the North Harrow application through every officer query to the decision.
North Harrow (HA2) sits primarily in Harrow, so applications are decided by Harrow Council. We confirm the planning route for your exact address before quoting.
Almost always. Any structural work behind planning permission drawings in North Harrow — new openings, steel beams, loft floors, foundations — needs Building Regulations approval covering structure (Part A), fire escape (Part B) and insulation (Part L), submitted to Harrow Council Building Control or an approved inspector. On HA2's typically terraced and semi-detached stock, a Party Wall notice to adjoining neighbours is normally required before the steelwork. We coordinate both as part of the Complete package.
In value terms, yes. The bigger risk is an unapproved or non-compliant scheme — which is why council-ready drawings and a clean Building Control sign-off matter on HA2 homes.
Householders often approach us after a neighbour used a different council. Our full range is set out for HA1, HA3, HA5 and HA7.
Pick a slot that suits you. No obligation and no sales pressure, just straight answers on your planning route.

How designation changes a HA2 (North Harrow / South Harrow) planning drawing set: Harrow Council maintains 29 conservation areas, including Harrow on the Hill, Pinner Village, Stanmore. Inside any of them a HA2 (North Harrow / South Harrow) planning drawing set cannot rely on permitted development, and the route becomes a £548 householder application determined in 8 weeks rather than a £249 prior approval in 6 weeks. Harrow Weald sets the tone for HA2 (North Harrow / South Harrow) casework.

A Lawful Development Certificate at £274 is how a HA2 owner records that a planning drawing set was lawful.
