Side return extension plans in Barlow & Holmesfield

What the data says about planning in Barlow & Holmesfield

North East Derbyshire District Council granted 93% of the householder planning decisions it made in its latest published year — 6 points above the 87% England-wide householder average. Barlow & Holmesfield contains Barlow, Barlow Grange, Barlow Mills and Crow Holes conservation areas (Barlow designated 1979), so materials, fenestration and roof form are assessed against the appraisal, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901) and 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 North East Derbyshire District Council needs a full application. In conservation areas such as Barlow, Barlow Grange and Barlow Mills and Crow Holes those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Barlow & Holmesfield is determined against an 8-week statutory target.

Barlow (conservation area designated in 1979), Barlow Grange (conservation area designated in 1990), Barlow Mills and Crow Holes (conservation area designated in 1990), Barlow Woodseats and Johnnygate (conservation area designated in 1990), Cartledge (conservation area designated in 1990), Holmesfield (conservation area designated in 1990), Horsley Gate and Cordwell (conservation area designated in 1990), Unthank (conservation area designated in 1990), Woodthorpe Hall and Fanshaw Gate (conservation area designated in 1990), Barlow (civil parish within Barlow & Holmesfield) and Holmesfield (civil parish within Barlow & Holmesfield) — these are the Barlow & Holmesfield pockets our drawings cover most. Heritage designations here include Barlow, Barlow Grange, Barlow Mills and Crow Holes, Barlow Woodseats and Johnnygate, Cartledge, Holmesfield, Horsley Gate and Cordwell, Unthank and Woodthorpe Hall and Fanshaw Gate. North East Derbyshire District Council weighs each proposal against North East Derbyshire District Council's development plan and the design policies it applies to householder applications, where the 920 homes here are 29% pre-1900, 15% 1945-1954, 13% 1955-1964, which is what sets the realistic roof and rear-projection options. On roofs the borough is steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and simple gabled and hipped roofs typical of early postwar building, over Victorian and earlier houses (29% of 920 homes), early postwar houses (15%) and late-1950s and early-1960s houses (13%).

Designations, stock and decisions in Barlow & Holmesfield

Heritage designation is the single biggest variable in Barlow & Holmesfield, and it is address-specific: Barlow (conservation area designated in 1979), Barlow Grange (conservation area designated in 1990), Barlow Mills and Crow Holes (conservation area designated in 1990), Barlow Woodseats and Johnnygate (conservation area designated in 1990), Cartledge (conservation area designated in 1990), Holmesfield (conservation area designated in 1990), Horsley Gate and Cordwell (conservation area designated in 1990), Unthank (conservation area designated in 1990) and Woodthorpe Hall and Fanshaw Gate (conservation area designated in 1990). Inside those boundaries permitted development is curtailed and North East Derbyshire 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, Barlow & Holmesfield takes in Barlow and Holmesfield. No Article 4 direction is recorded for North East Derbyshire District Council, but Barlow & Holmesfield's 9 conservation areas still limit permitted development on those streets.

On stock, Barlow & Holmesfield is Victorian and earlier houses (29% of 920 homes), early postwar houses (15%) and late-1950s and early-1960s houses (13%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and simple gabled and hipped roofs typical of early postwar building govern what a loft or rear projection can realistically be. North East Derbyshire District Council decided 304 householder applications in the latest published year and granted 93%, with 62% issued inside the eight-week target. We work from the council's own published record.

The full build-period split for Barlow & Holmesfield runs pre-1900 29% (270 homes), 1900-1918 2% (20 homes), 1919-1929 3% (30 homes), 1930-1939 8% (70 homes), 1945-1954 15% (140 homes), 1955-1964 13% (120 homes), 1965-1972 3% (30 homes), 1973-1982 8% (70 homes), 1983-1992 4% (40 homes), 1993-1999 1% (10 homes) and 2000-2008 3% (30 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.

North East Derbyshire District Council also decides for Brampton & Walton, Clay Cross North, Coal Aston, Holmewood & Heath, Pilsley & Morton, Ridgeway & Marsh Lane, Shirland and Sutton, so a decision in Barlow & Holmesfield 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.

Side returns drawn for Barlow & Holmesfield's period terraces

The side return is the classic terrace fix, and Barlow & Holmesfield has the stock for it — the borough is built largely from Victorian and earlier houses (29% of 920 homes), early postwar houses (15%) and late-1950s and early-1960s houses (13%), and the Victorian and Edwardian versions almost all have an L-shaped back addition with a wasted alley beside it. Fill that alley and the dark galley kitchen becomes a bright, square room the full width of the house. North East Derbyshire District Council judges the infill against North East Derbyshire District Council's development plan and the design policies it applies to householder applications, and because it runs along the party boundary, the neighbour relationship is read before the design.

That boundary is where the drawings earn their keep. We set the infill wall on or up to the line, keep the roof — usually a glazed lantern or a shallow pitch tying into the existing back-addition slope — below the neighbour's first-floor windows, and detail the rainwater and party-wall junction so the build is watertight and the Party Wall Act is satisfied. Barlow & Holmesfield contains Barlow, Barlow Grange, Barlow Mills and Crow Holes conservation areas (Barlow designated 1979), so materials, fenestration and roof form are assessed against the appraisal, so we resolve it on the section rather than leave it to the case officer.

Many of Barlow & Holmesfield's terraces sit in conservation areas — Barlow, Barlow Grange, Barlow Mills and Crow Holes, Barlow Woodseats and Johnnygate, Cartledge, Holmesfield, Horsley Gate and Cordwell, Unthank and Woodthorpe Hall and Fanshaw Gate among them — where a side extension is no longer permitted development. No Article 4 direction is recorded for North East Derbyshire District Council, but Barlow & Holmesfield's 9 conservation areas still limit permitted development on those streets. We confirm the designation before a line is drawn.
