Side-return infill drawings for Evington terraces — the glazed extension that fills the redundant side alley and opens up the kitchen, drawn to Leicester City Council's guidance, delivered in days and revised free until your decision, with a free approval-odds check first.
Leicester City Council granted 87% of the householder planning decisions it made in its latest published year — level with the 87% England-wide householder average. The two Evington conservation areas — the village and the footpath — protect the old core and its green setting, shaping extension design nearby, 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.
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 Leicester City Council needs a full application. Evington carries at least one Article 4 direction, and conservation areas including Evington village, Evington footpath and Spinney Hill Park remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Evington is determined against an 8-week statutory target.
Evington Village (the historic core with the conservation area and old cottages), Evington Lane (suburban semis lining the route out to the village), Downing Drive (postwar semi-detached estates with generous plots), Goodwood (later suburban housing on the eastern edge), Coleman Road (denser interwar and Victorian streets towards the city) and Spinney Hills (Victorian terraces framing Spinney Hill Park) — these are the Evington pockets our drawings cover most. Heritage designations here include Evington village, Evington footpath and Spinney Hill Park. Leicester City Council weighs each proposal against the Leicester Local Plan and the Evington conservation area appraisals, where the interwar and postwar semis are policed for spacing and building line so paired houses retain their suburban rhythm. On roofs the borough is hipped roofs on the interwar and postwar semis and gabled slate roofs on the older village houses, over interwar and postwar semi-detached houses with gardens, Victorian terraces on the streets closer to the city and larger detached properties around Evington village.
The side return is the classic terrace fix, and Evington has the stock for it — the borough is built largely from interwar and postwar semi-detached houses with gardens, Victorian terraces on the streets closer to the city and larger detached properties around Evington village, 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. Leicester City Council judges the infill against the Leicester Local Plan and the Evington conservation area appraisals, 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 two Evington conservation areas — the village and the footpath — protect the old core and its green setting, shaping extension design nearby, so we resolve it on the section rather than leave it to the case officer.
Many of Evington's terraces sit in conservation areas — Evington village, Evington footpath and Spinney Hill Park among them — where a side extension is no longer permitted development. The Evington village and Evington footpath conservation areas carry heritage controls, and the 2022 HMO Article 4 extension into the Spinney Hills fringe means conversions to small HMOs there need planning permission. We confirm the designation before a line is drawn.
Some single-storey side returns in Evington 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 Leicester 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 Leicester 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 Leicester City Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Leicester grants the large majority of householder applications, and in Evington the constraints run from the village conservation core to the protected semi-detached suburban streets. 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 Evington Village, Evington Lane and Downing Drive, 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 interwar and postwar semi-detached houses with gardens, 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 interwar and postwar semis are policed for spacing and building line so paired houses retain their suburban rhythm. 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 Leicester 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 Evington side returns come up most often:

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