Side-return infill drawings for Stivichall terraces — the glazed extension that fills the redundant side alley and opens up the kitchen, drawn to Coventry City Council's guidance, delivered in days and revised free until your decision, with a free approval-odds check first.
Coventry City Council granted 86% of the householder planning decisions it made in its latest published year — 1 point below the 87% England-wide householder average. The tree-lined Kenilworth Road conservation area — protected in part through National Trust ownership of the verges — tightly limits bulk, roofs and boundary changes on its frontages, which is where a policy-literate drawing pack earns its keep. Its dominant interwar (1918–1939) and postwar (1945–1970) housing stock sets the design brief on most streets.
The permitted-development ceilings are fixed: 40m³ of new roof volume for a terraced loft and 50m³ for a semi or detached house under Class B, plus a 3m single-storey rear extension on a terrace or 4m on a detached house under Class A. Stivichall carries at least one Article 4 direction, and conservation areas including Kenilworth Road and London Road remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Stivichall is determined against an 8-week statutory target.
Styvechale (spacious interwar semis and detached homes south of War Memorial Park), Kenilworth Road (the avenue of large villas set behind the National Trust-owned tree belt, a conservation area), Green Lane (1930s semis on the western side of the district), Styvechale Grange (later detached estates toward the A45), Baginton fringe (green-edge plots on the southern boundary) and War Memorial Park edge (interwar houses fronting the city's largest park) — these are the Stivichall pockets our drawings cover most. Heritage designations here include Kenilworth Road and London Road. Coventry City Council weighs each proposal against the Coventry Local Plan (2017), where the generous interwar plots invite large extensions, but officers weigh their impact on the leafy, low-density suburban character. On roofs the borough is hipped roofs on the interwar semis and detached homes and steeper gables on the larger Kenilworth Road villas, over 1930s interwar detached and semi-detached houses, larger detached homes on the Kenilworth Road approach and post-war and later suburban infill.
The side return is the classic terrace fix, and Stivichall has the stock for it — the borough is built largely from 1930s interwar detached and semi-detached houses, larger detached homes on the Kenilworth Road approach and post-war and later suburban infill, 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. Coventry City Council judges the infill against the Coventry Local Plan (2017), 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. The tree-lined Kenilworth Road conservation area — protected in part through National Trust ownership of the verges — tightly limits bulk, roofs and boundary changes on its frontages, so we resolve it on the section rather than leave it to the case officer.
Many of Stivichall's terraces sit in conservation areas — Kenilworth Road and London Road among them — where a side extension is no longer permitted development. Stivichall (also spelt Styvechale) sits in Wainbody ward, which is named in Coventry's citywide Article 4 direction (from 30 September 2023), so a house-to-small-HMO conversion requires a change-of-use application here. We confirm the designation before a line is drawn.
Some single-storey side returns in Stivichall 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 Coventry City 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 Coventry City 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 Coventry City Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Stivichall approves most householder schemes, with the Kenilworth Road conservation area and the low-density interwar character setting the ceiling on roof and side additions. 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 Styvechale, Kenilworth Road and Green Lane, 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 1930s interwar detached and semi-detached houses, 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 generous interwar plots invite large extensions, but officers weigh their impact on the leafy, low-density suburban character. 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 Coventry City 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 Stivichall side returns come up most often:

Whether a side return in Stivichall 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 Coventry City 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 Kenilworth Road and London Road, side extensions are not permitted development and always need a full application.
A fixed process built around how Coventry City Council validates and decides side-return applications — most drawings are submission-ready within seven days of survey.
Send us your Stivichall 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 Coventry City 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 Coventry City 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 Coventry City 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 Stivichall you will need a full application to Coventry City Council for anything wider or taller, for a two-storey side return, and for any side extension in a conservation area such as Kenilworth Road and London Road, 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. Stivichall's period terraces are ideally suited to it, which is why the side return is one of the borough's most common extensions. Coventry City 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 Coventry City 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 Stivichall 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 Coventry City 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 Stivichall address specifically.
A householder planning application in Stivichall 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. Coventry City Council is the decision-maker.
We price each Stivichall 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 Coventry City Council approves, and we confirm at the outset whether your infill is permitted development or needs an application.
