Side-return infill drawings for Mid Holderness terraces — the glazed extension that fills the redundant side alley and opens up the kitchen, drawn to East Riding of Yorkshire Council's guidance, delivered in days and revised free until your decision, with a free approval-odds check first.
East Riding of Yorkshire Council granted 92% of the householder planning decisions it made in its latest published year — 5 points above the 87% England-wide householder average. Mid Holderness contains Aldbrough, Burton Pidsea East, Burton Pidsea West conservation areas (Aldbrough designated 1974), so materials, fenestration and roof form are assessed against the appraisal, which is where a policy-literate drawing pack earns its keep. Its dominant 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. Mid Holderness carries at least one Article 4 direction, and conservation areas including Aldbrough, Burton Pidsea East and Burton Pidsea West remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Mid Holderness is determined against an 8-week statutory target.
Aldbrough (conservation area designated in 1974), Burton Pidsea East (conservation area designated in 1974), Burton Pidsea West (conservation area designated in 1974), Catwick (conservation area designated in 2006), Great Hatfield (conservation area designated in 1994), Lelley (conservation area designated in 1991), Long Riston (conservation area designated in 2009), Sproatley North (conservation area designated in 1987), Sproatley South (conservation area designated in 1987), Swine (conservation area designated in 1991), Withernwick (conservation area designated in 2010), Wyton (conservation area designated in 1991), Aldbrough (civil parish within Mid Holderness), Bilton (civil parish within Mid Holderness), Burstwick (civil parish within Mid Holderness), Burton Constable (civil parish within Mid Holderness), Burton Pidsea (civil parish within Mid Holderness) and Catwick (civil parish within Mid Holderness) — these are the Mid Holderness pockets our drawings cover most. Heritage designations here include Aldbrough, Burton Pidsea East, Burton Pidsea West, Catwick, Great Hatfield, Lelley, Long Riston, Sproatley North, Sproatley South, Swine, Withernwick and Wyton. East Riding of Yorkshire Council weighs each proposal against East Riding of Yorkshire Council's development plan and the design policies it applies to householder applications, where the 6,270 homes here are 15% 1973-1982, 15% 1965-1972, 14% 1955-1964, which is what sets the realistic roof and rear-projection options. On roofs the borough is shallow trussed roofs typical of 1970s building and shallow-pitched roofs and integral garages typical of that period's building, over 1970s and early-1980s houses (15% of 6,270 homes), late-1960s and early-1970s houses (15%) and late-1950s and early-1960s houses (14%).
Mid Holderness's designated heritage is specific, and it is the first thing we check against your address: Aldbrough (conservation area designated in 1974), Burton Pidsea East (conservation area designated in 1974), Burton Pidsea West (conservation area designated in 1974), Catwick (conservation area designated in 2006), Great Hatfield (conservation area designated in 1994), Lelley (conservation area designated in 1991), Long Riston (conservation area designated in 2009), Sproatley North (conservation area designated in 1987), Sproatley South (conservation area designated in 1987), Swine (conservation area designated in 1991), Withernwick (conservation area designated in 2010) and Wyton (conservation area designated in 1991). Inside those boundaries permitted development is curtailed and East Riding of Yorkshire 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, Mid Holderness takes in Aldbrough, Bilton, Burstwick, Burton Constable, Burton Pidsea and Catwick. East Riding of Yorkshire Council has 11 recorded Article 4 directions, removing permitted development for rear and side extensions — check the address before assuming PD applies in Mid Holderness.
On stock, Mid Holderness is 1970s and early-1980s houses (15% of 6,270 homes), late-1960s and early-1970s houses (15%) and late-1950s and early-1960s houses (14%) — which is why shallow trussed roofs typical of 1970s building and shallow-pitched roofs and integral garages typical of that period's building govern what a loft or rear projection can realistically be. East Riding of Yorkshire Council decided 830 householder applications in the latest published year and granted 92%, with 95% issued inside the eight-week target. Those are the numbers our drawings are prepared against.
The full build-period split for Mid Holderness runs pre-1900 14% (870 homes), 1900-1918 2% (100 homes), 1919-1929 1% (40 homes), 1930-1939 8% (520 homes), 1945-1954 4% (280 homes), 1955-1964 14% (900 homes), 1965-1972 15% (910 homes), 1973-1982 15% (970 homes), 1983-1992 7% (460 homes), 1993-1999 7% (440 homes) and 2000-2008 7% (420 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.
East Riding of Yorkshire Council also decides for Beverley Rural, Bridlington North, Bridlington South, Dale, Driffield and Rural, East Wolds and Coastal, Goole South and Hessle, so a decision in Mid Holderness 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 Article 4 directions recorded for this council include Alpine Villa (Beck Cottage), Atwick, Atwick Hall, Atwick, Clifton House, Atwick and Green View, Atwick. Each removes a specific permitted-development right inside its own boundary, which is why the check is done on the address rather than on the town.

The side return is the classic terrace fix, and Mid Holderness has the stock for it — the borough is built largely from 1970s and early-1980s houses (15% of 6,270 homes), late-1960s and early-1970s houses (15%) and late-1950s and early-1960s houses (14%), 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. East Riding of Yorkshire Council judges the infill against East Riding of Yorkshire 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. Mid Holderness contains Aldbrough, Burton Pidsea East, Burton Pidsea West conservation areas (Aldbrough designated 1974), 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 Mid Holderness's terraces sit in conservation areas — Aldbrough, Burton Pidsea East, Burton Pidsea West, Catwick, Great Hatfield, Lelley, Long Riston, Sproatley North, Sproatley South, Swine, Withernwick and Wyton among them — where a side extension is no longer permitted development. East Riding of Yorkshire Council has 11 recorded Article 4 directions, removing permitted development for rear and side extensions — check the address before assuming PD applies in Mid Holderness. We confirm the designation before a line is drawn.
Some single-storey side returns in Mid Holderness 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 East Riding of Yorkshire 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 East Riding of Yorkshire 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 East Riding of Yorkshire Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. East Riding of Yorkshire Council granted 92% of its householder applications in the year to 31 March 2026, and Aldbrough 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 Aldbrough, Burton Pidsea East and Burton Pidsea West, 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 1970s and early-1980s houses (15% of 6,270 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 6,270 homes here are 15% 1973-1982, 15% 1965-1972, 14% 1955-1964, 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 East Riding of Yorkshire 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 Mid Holderness side returns come up most often:

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