Planning application drawings in Holbrook West

What the data says about planning in Holbrook West

Horsham District Council granted 97% of the householder planning decisions it made in its latest published year — 10 points above the 87% England-wide householder average. Holbrook West contains the Horsham (Richmond Road) Conservation Area conservation area (Horsham (Richmond Road) Conservation Area designated 1989), so materials, fenestration and roof form are assessed against the appraisal, which is where a policy-literate drawing pack earns its keep. Its dominant postwar (1945–1970) housing stock sets the design brief on most streets.

Class A and Class B set the thresholds — a rear dormer to 40m³ on a terrace or 50m³ on a semi or detached, and a single-storey rear extension to 3m on a terrace or 4m on a detached house — beyond which Horsham District Council needs a full application. Holbrook West carries at least one Article 4 direction, and conservation areas including Horsham (Richmond Road) Conservation Area remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Holbrook West is determined against an 8-week statutory target.

Horsham (Richmond Road) (conservation area designated in 1989) and North Horsham (civil parish within Holbrook West) — these are the Holbrook West pockets our drawings cover most. Heritage designations here include Horsham (Richmond Road) Conservation Area. Horsham District Council weighs each proposal against Horsham District Council's adopted local plan and its householder design guidance, where the 3,510 homes here are 20% 1973-1982, 18% 1965-1972, 13% 1993-1999, which is what sets the realistic roof and rear-projection options. On roofs the borough is shallow trussed roofs typical of 1970s building and shallow-pitched roofs and integral garages typical of that period's building, over 1970s and early-1980s houses (20% of 3,510 homes), late-1960s and early-1970s houses (18%) and 1990s estate houses (13%).

Designations, stock and decisions in Holbrook West

Heritage designation is the single biggest variable in Holbrook West, and it is address-specific: Horsham (Richmond Road) (conservation area designated in 1989). Inside those boundaries permitted development is curtailed and Horsham District Council assesses materials, window detail and roof form against the area's own appraisal, so a scheme that would be waved through two streets away can need a full application here.

Beyond the designated areas, Holbrook West takes in North Horsham. Horsham District Council has 53 recorded Article 4 directions, removing permitted development for rear and side extensions and roof enlargements such as dormers — check the address before assuming PD applies in Holbrook West.

On stock, Holbrook West is 1970s and early-1980s houses (20% of 3,510 homes), late-1960s and early-1970s houses (18%) and 1990s estate houses (13%) — which is why shallow trussed roofs typical of 1970s building and shallow-pitched roofs and integral garages typical of that period's building govern what a loft or rear projection can realistically be. Horsham District Council decided 679 householder applications in the latest published year and granted 97%, with 72% issued inside the eight-week target. We work from the council's own published record.

The full build-period split for Holbrook West runs pre-1900 11% (390 homes), 1900-1918 2% (70 homes), 1919-1929 1% (30 homes), 1930-1939 3% (100 homes), 1945-1954 2% (70 homes), 1955-1964 8% (280 homes), 1965-1972 18% (620 homes), 1973-1982 20% (690 homes), 1983-1992 11% (380 homes), 1993-1999 13% (450 homes) and 2000-2008 4% (150 homes). That distribution is why pre-1900 detailing dominates the drawings here, and it is measured from council-tax records rather than assumed from the street name.

Horsham District Council also decides for Billingshurst, Colgate & Rusper, Denne and Steyning & Ashurst, so a decision in Holbrook West sits inside a wider pattern of decisions we track across the same authority — useful when an officer cites a precedent from the next area over.

The Article 4 directions recorded for this council include ART4002 - LAND AT WOLVENS FARM BILLINGSHURST ROAD ASHINGTON, ART4003 - LAND AT CODMORE HILL PULBOROUGH, ART4020/1 and ART4040. Each removes a specific permitted-development right inside its own boundary, which is why the check is done on the address rather than on the town.

What goes in a Holbrook West planning application

Whatever you are building, Horsham District Council decides it from the same core set. A location plan at 1:1250 fixes the site on the map with the red-line boundary; a block plan at 1:500 shows the property in its plot; then existing and proposed floor plans and elevations at 1:100 or 1:50 show the house as it is and as it will be. Larger schemes add a section and, where policy requires, a design and access statement. Miss one and the application is returned invalid before an officer has looked at it.

The drawings are also the argument. Horsham District Council assesses each proposal against Horsham District Council's adopted local plan and its householder design guidance, and the elevations are where the case is won or lost — ridge and eaves heights, window positions, materials and how the change reads from the street. On Holbrook West's stock, which runs to 1970s and early-1980s houses (20% of 3,510 homes), late-1960s and early-1970s houses (18%) and 1990s estate houses (13%), the same scheme is drawn differently to answer the concerns officers raise here. Holbrook West contains the Horsham (Richmond Road) Conservation Area conservation area (Horsham (Richmond Road) Conservation Area designated 1989), so materials, fenestration and roof form are assessed against the appraisal, so the pack is built to pre-empt exactly that.

Where the property sits in a conservation area — Horsham (Richmond Road) Conservation Area among Holbrook West's — validation is stricter still, often demanding heritage detail and sometimes additional plans. Horsham District Council has 53 recorded Article 4 directions, removing permitted development for rear and side extensions and roof enlargements such as dormers — check the address before assuming PD applies in Holbrook West. We confirm the designation before drawing so the pack meets the higher bar first time.
