Side-return infill drawings for Edgmond terraces — the glazed extension that fills the redundant side alley and opens up the kitchen, drawn to Telford & Wrekin Council's guidance, delivered in days and revised free until your decision, with a free approval-odds check first.
Telford & Wrekin Council granted 91% of the householder planning decisions it made in its latest published year — 4 points above the 87% England-wide householder average. Edgmond contains the Edgmond conservation area, 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.
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 Edgmond those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Edgmond is determined against an 8-week statutory target.
Edgmond (designated conservation area), Tibberton and Cherrington (civil parish within Edgmond) and Chetwynd (civil parish within Edgmond) — these are the Edgmond pockets our drawings cover most. Heritage designations here include Edgmond. Telford & Wrekin Council weighs each proposal against Telford & Wrekin Council's development plan and the design policies it applies to householder applications, where the 1,330 homes here are 25% pre-1900, 20% 1955-1964, 11% 1973-1982, 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 shallow gabled roofs typical of that period's building, over Victorian and earlier houses (25% of 1,330 homes), late-1950s and early-1960s houses (20%) and 1970s and early-1980s houses (11%).
Edgmond's designated heritage is specific, and it is the first thing we check against your address: Edgmond (designated conservation area). Inside those boundaries permitted development is curtailed and Telford & Wrekin 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, Edgmond takes in Tibberton and Cherrington and Chetwynd. No Article 4 direction is recorded for Telford & Wrekin Council, but Edgmond's 1 conservation area still limit permitted development on those streets.
On stock, Edgmond is Victorian and earlier houses (25% of 1,330 homes), late-1950s and early-1960s houses (20%) and 1970s and early-1980s houses (11%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and shallow gabled roofs typical of that period's building govern what a loft or rear projection can realistically be. Telford & Wrekin Council decided 277 householder applications in the latest published year and granted 91%, with 96% issued inside the eight-week target. Those are the numbers our drawings are prepared against.
The full build-period split for Edgmond runs pre-1900 25% (330 homes), 1900-1918 2% (30 homes), 1919-1929 1% (10 homes), 1930-1939 4% (50 homes), 1945-1954 5% (70 homes), 1955-1964 20% (260 homes), 1965-1972 5% (60 homes), 1973-1982 11% (140 homes), 1983-1992 3% (40 homes), 1993-1999 4% (50 homes) and 2000-2008 5% (60 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.
Telford & Wrekin Council also decides for Ercall Magna, Horsehay & Lightmoor, Ironbridge Gorge and Wrockwardine, so a decision in Edgmond 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 Edgmond has the stock for it — the borough is built largely from Victorian and earlier houses (25% of 1,330 homes), late-1950s and early-1960s houses (20%) and 1970s and early-1980s houses (11%), 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. Telford & Wrekin Council judges the infill against Telford & Wrekin 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. Edgmond contains the Edgmond conservation area, 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 Edgmond's terraces sit in conservation areas — Edgmond among them — where a side extension is no longer permitted development. No Article 4 direction is recorded for Telford & Wrekin Council, but Edgmond's 1 conservation area still limit permitted development on those streets. We confirm the designation before a line is drawn.
Some single-storey side returns in Edgmond 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 Telford & Wrekin 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 Telford & Wrekin 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 Telford & Wrekin Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Telford & Wrekin Council granted 91% of its householder applications in the year to 31 March 2026, and Edgmond 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 Edgmond, Tibberton and Cherrington and Chetwynd, 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 victorian and earlier houses (25% of 1,330 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 1,330 homes here are 25% pre-1900, 20% 1955-1964, 11% 1973-1982, 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 Telford & Wrekin 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 Edgmond side returns come up most often:

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