Side-return infill drawings for Langwith terraces — the glazed extension that fills the redundant side alley and opens up the kitchen, drawn to Bolsover District Council's guidance, delivered in days and revised free until your decision, with a free approval-odds check first.
Bolsover District Council granted 98% of the householder planning decisions it made in its latest published year — 11 points above the 87% England-wide householder average. Langwith contains Apsley Grange, Upper Langwith conservation areas (Apsley Grange designated 1995), 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), interwar (1918–1939) and postwar (1945–1970) housing stock sets the design brief on most streets.
Under Class B, a rear dormer stays permitted development up to 40m³ of added roof volume on a terrace or 50m³ on a semi-detached or detached house, while Class A allows a single-storey rear extension of 3m beyond the original rear wall on a terrace and 4m on a detached house before a full application is needed. In conservation areas such as Apsley Grange and Upper Langwith those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Langwith is determined against an 8-week statutory target.
Apsley Grange (conservation area designated in 1995), Upper Langwith (conservation area designated in 1979) and Shirebrook (civil parish within Langwith) — these are the Langwith pockets our drawings cover most. Heritage designations here include Apsley Grange and Upper Langwith. Bolsover District Council weighs each proposal against Bolsover District Council's adopted local plan and its householder design guidance, where the 1,950 homes here are 25% 1919-1929, 14% pre-1900, 12% 1945-1954, which is what sets the realistic roof and rear-projection options. On roofs the borough is hipped tiled roofs typical of early interwar building and steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building, over early interwar houses (25% of 1,950 homes), Victorian and earlier houses (14%) and early postwar houses (12%).
Langwith's designated heritage is specific, and it is the first thing we check against your address: Apsley Grange (conservation area designated in 1995) and Upper Langwith (conservation area designated in 1979). Inside those boundaries permitted development is curtailed and Bolsover 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, Langwith takes in Shirebrook. No Article 4 direction is recorded for Bolsover District Council, but Langwith's 2 conservation areas still limit permitted development on those streets.
On stock, Langwith is early interwar houses (25% of 1,950 homes), Victorian and earlier houses (14%) and early postwar houses (12%) — which is why hipped tiled roofs typical of early interwar building and steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building govern what a loft or rear projection can realistically be. Bolsover District Council decided 130 householder applications in the latest published year and granted 98%, with 77% issued inside the eight-week target. Those are the numbers our drawings are prepared against.
The full build-period split for Langwith runs pre-1900 14% (270 homes), 1900-1918 4% (80 homes), 1919-1929 25% (480 homes), 1930-1939 4% (70 homes), 1945-1954 12% (230 homes), 1955-1964 3% (60 homes), 1965-1972 10% (200 homes), 1973-1982 1% (10 homes), 1983-1992 2% (40 homes), 1993-1999 8% (150 homes) and 2000-2008 7% (140 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.
Bolsover District Council also decides for Ault Hucknall, Barlborough, Blackwell, Bolsover East, Bolsover South, Clowne East, Elmton-with-Creswell and Shirebrook South, so a decision in Langwith 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 side return is the classic terrace fix, and Langwith has the stock for it — the borough is built largely from early interwar houses (25% of 1,950 homes), Victorian and earlier houses (14%) and early postwar houses (12%), 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. Bolsover District Council judges the infill against Bolsover District Council's adopted local plan and its householder design guidance, 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. Langwith contains Apsley Grange, Upper Langwith conservation areas (Apsley Grange designated 1995), 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 Langwith's terraces sit in conservation areas — Apsley Grange and Upper Langwith among them — where a side extension is no longer permitted development. No Article 4 direction is recorded for Bolsover District Council, but Langwith's 2 conservation areas still limit permitted development on those streets. We confirm the designation before a line is drawn.
Some single-storey side returns in Langwith are permitted development, but the width and boundary make an application more likely than for a straight rear extension. You will normally need to apply to Bolsover District Council if any of these apply:
We draw the infill wall on the boundary, the glazed roof below the neighbour's windows and the party-wall junction on the page — the details Bolsover District Council's officers and your neighbour both check — and submit a validation-complete pack, whether that is a lawful development certificate or a full householder application.
Below is Bolsover District Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Bolsover District Council granted 98% of its householder applications in the year to 31 March 2026, and Apsley Grange shapes what is approved here. Side returns hinge on width, roof glazing and the party boundary, so a pack that resolves those details upfront is decided faster and refused less often than a DIY submission.

Across Apsley Grange, Upper Langwith and Shirebrook, the approved side return is a single-storey infill roofed with a glazed lantern or roof light to pull daylight deep into the plan, its flank wall built on the boundary and finished to match the host brick. On the borough's early interwar houses (25% of 1,950 homes), this is frequently the single biggest gain in usable ground-floor space, and where it stays within the width and height limits it can proceed under permitted development or a lawful development certificate.
The 1,950 homes here are 25% 1919-1929, 14% pre-1900, 12% 1945-1954, which is what sets the realistic roof and rear-projection options. We keep the glazed roof below the neighbour's cill line, set the gutter and the party-wall flashing so water and maintenance are designed in, and — where owners want the full open-plan room — pair the infill with a rear extension as a single wraparound application. That way Bolsover District Council sees one coherent scheme rather than two overlapping ones.
We draw side-return infills on every terraced street in the borough. A few of the neighbourhoods where Langwith side returns come up most often:
Side return extension drawings for Apsley Grange's conservation area designated in 1995 — width-checked, party-wall detailed and drawn to Bolsover District Council's guidance.
Side return extension drawings for Upper Langwith's conservation area designated in 1979 — width-checked, party-wall detailed and drawn to Bolsover District Council's guidance.
Side return extension drawings for Shirebrook's civil parish within Langwith — width-checked, party-wall detailed and drawn to Bolsover District Council's guidance.
Whether a side return in Langwith needs permission comes down to width, storeys and whether the street is designated. This is how the cases compare.
| Side return type | Permitted development? | What it gains | What Bolsover District Council checks |
|---|---|---|---|
| Single-storey infill, within limits | Often yes, if under half the house width | Full-width kitchen-diner | Width, 4m height, roof glazing |
| Single-storey, over half width | No — full application | Wider room, more light | Boundary treatment, neighbour amenity |
| Two-storey side return | No — full application | Room above as well as below | Bulk, overlooking, terrace rhythm |
| Wraparound (side + rear) | No — full application | L-shaped open-plan ground floor | Combined footprint, garden retained |
In conservation areas such as Apsley Grange and Upper Langwith, side extensions are not permitted development and always need a full application.
A fixed process built around how Bolsover District Council validates and decides side-return applications — most drawings are submission-ready within seven days of survey.
Send us your Langwith postcode and terrace type. We confirm your conservation and Article 4 status, whether the infill stays within the side-extension width limit, and score your odds against live Bolsover District Council decisions.
We measure the side alley, the back-addition wall, floor and eaves levels and the neighbour's window heights — the numbers the width limit, roof pitch and party-wall detailing depend on.
Chartered designers develop the infill and its glazed roof to your brief, drawn inside the permitted-development limits or to Bolsover District Council's extension guidance, with the boundary and party-wall junction detailed.
We submit the certificate or application, manage validation and case-officer queries, and revise the drawings free until Bolsover District Council issues its decision.
Sometimes not. A single-storey side-return infill can be permitted development if it is no wider than half the original house, no higher than 4 metres, and the property is not on designated land. In Langwith you will need a full application to Bolsover District Council for anything wider or taller, for a two-storey side return, and for any side extension in a conservation area such as Apsley Grange and Upper Langwith, where those rights are removed.
It is an infill that fills the narrow open alley running alongside the rear back-addition of a Victorian or Edwardian terrace — the strip of ground that is usually too small to use. Building over it squares off the ground floor, so a cramped galley kitchen becomes a full-width room. Langwith's period terraces are ideally suited to it, which is why the side return is one of the borough's most common extensions. Bolsover District Council is the decision-maker.
Almost always. A side return is built on or up to the boundary with your neighbour, so the Party Wall etc. Act applies and you must serve notice before work starts — this is entirely separate from Bolsover District Council's planning decision. We detail the party-wall junction on the drawings and flag the notice early so a surveyor can be appointed without delaying the build. This applies to your Langwith address specifically.
Yes, and it is common — the combined L-shape is a wraparound extension. Once the side infill joins a rear projection beyond the permitted-development depth, the whole thing needs a full householder application to Bolsover District Council rather than qualifying as permitted development. We draw it as one coherent scheme so the council assesses a single footprint, which reads more clearly than two overlapping proposals. This applies to your Langwith address specifically.
A householder planning application in Langwith runs to a statutory eight-week target, and a lawful development certificate to eight weeks as well, though an incomplete pack can stall at validation. Because a side return involves the boundary and roof glazing, a complete, well-detailed submission matters — we prepare it validation-complete and manage officer queries to keep the decision on track. Bolsover District Council is the decision-maker.
We price each Langwith side return individually, because alley width and roof form vary house to house, and send a fixed, no-obligation quote within one working day. It covers the full drawing pack with free revisions until Bolsover District Council approves, and we confirm at the outset whether your infill is permitted development or needs an application.
