Side-return infill drawings for Spondon terraces — the glazed extension that fills the redundant side alley and opens up the kitchen, drawn to Derby City Council's guidance, delivered in days and revised free until your decision, with a free approval-odds check first.
Derby City Council granted 93% of the householder planning decisions it made in its latest published year — 6 points above the 87% England-wide householder average. The Spondon conservation area protects the church, Green and Georgian-Victorian frontages of the historic village core, which is where a policy-literate drawing pack earns its keep. Its dominant Georgian (1714–1837), Victorian (1837–1901), interwar (1918–1939) and postwar (1945–1970) housing stock sets the design brief on most streets.
Before permission is required, Class B allows 40m³ of added loft volume on a terrace and 50m³ on a semi or detached house, and Class A allows a 3m single-storey rear extension on a terrace or 4m on a detached house. In conservation areas such as Spondon and Nottingham Road those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Spondon is determined against an 8-week statutory target.
Spondon village (the historic core around St Werburgh's Church and the Green), Church Street (Georgian and Victorian frontages in the conservation-area heart), Chapel Side (older cottages and period houses near the village centre), Lodge Lane (interwar and postwar semi-detached streets), Locko Road (later suburban housing running north-east from the village) and Borrowash Road (20th-century semis and detached houses towards the eastern boundary) — these are the Spondon pockets our drawings cover most. Heritage designations here include Spondon and Nottingham Road. Derby City Council weighs each proposal against the Derby City Local Plan Part 1 (Core Strategy) and Part 2, where suburban spacing and building-line policy governs the interwar and postwar semis so paired groups keep their rhythm. On roofs the borough is gabled roofs on the older village houses and hipped roofs on the interwar and postwar semis, over a former village core of Georgian and Victorian houses around the church, interwar and postwar semi-detached suburbia and later 20th-century detached estates.
The side return is the classic terrace fix, and Spondon has the stock for it — the borough is built largely from a former village core of Georgian and Victorian houses around the church, interwar and postwar semi-detached suburbia and later 20th-century detached estates, 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. Derby City Council judges the infill against the Derby City Local Plan Part 1 (Core Strategy) and Part 2, 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 Spondon conservation area protects the church, Green and Georgian-Victorian frontages of the historic village core, so we resolve it on the section rather than leave it to the case officer.
Many of Spondon's terraces sit in conservation areas — Spondon and Nottingham Road among them — where a side extension is no longer permitted development. Spondon lies on the eastern edge of the city outside the Ring Road, so it falls outside Derby's inner-city HMO Article 4 direction; the historic village centre is protected by the Spondon conservation area. We confirm the designation before a line is drawn.
Some single-storey side returns in Spondon 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 Derby 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 Derby 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 Derby City Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Derby approves most applications it decides, and in Spondon the recurring constraints are village-core conservation and suburban spacing standards rather than HMO pressure. 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 Spondon village, Church Street and Chapel Side, 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 a former village core of georgian and victorian houses around the church, 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.
Suburban spacing and building-line policy governs the interwar and postwar semis so paired groups keep their 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 Derby 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 Spondon side returns come up most often:

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