Side-return infill drawings for Redlands terraces — the glazed extension that fills the redundant side alley and opens up the kitchen, drawn to Reading Borough Council's guidance, delivered in days and revised free until your decision, with a free approval-odds check first.
Reading Borough Council granted 87% of the householder planning decisions it made in its latest published year — level with the 87% England-wide householder average. The HMO Article 4 direction means planning permission is normally refused where a new HMO would push the share of HMOs within a 50-metre radius above 25 per cent, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901) and Edwardian (1901–1910) 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. Redlands carries at least one Article 4 direction, and conservation areas including Redlands, Kendrick and Christchurch remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Redlands is determined against an 8-week statutory target.
Redlands (grand Victorian villas heavily converted to flats and HMOs), University (Whiteknights) (student rentals around the Whiteknights campus), Erleigh Road (long red-brick Victorian terraces east of the centre), Kendrick (substantial Victorian houses in the Kendrick conservation area), Christchurch (Victorian and Edwardian streets in the Christchurch conservation area) and London Road (villas around the university's historic London Road campus) — these are the Redlands pockets our drawings cover most. Heritage designations here include Redlands, Kendrick, Christchurch and Alexandra Road. Reading Borough Council weighs each proposal against the Reading Borough Local Plan (2019), where converting family houses to further flats or student rooms is resisted and is frequently the deciding issue. Much of Redlands is already converted flats, HMOs and student housing, which hold no householder permitted-development rights of their own.. On roofs the borough is pitched and gabled roofs on the villas and terraces and valley roofs behind the larger Victorian houses, over large Victorian and Edwardian villas subdivided into flats and HMOs, red-brick Victorian terraces off the London and Erleigh roads and student and rented housing around the university.
The side return is the classic terrace fix, and Redlands has the stock for it — the borough is built largely from large Victorian and Edwardian villas subdivided into flats and HMOs, red-brick Victorian terraces off the London and Erleigh roads and student and rented housing around the university, 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. Reading Borough Council judges the infill against the Reading Borough Local Plan (2019), 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 HMO Article 4 direction means planning permission is normally refused where a new HMO would push the share of HMOs within a 50-metre radius above 25 per cent, so we resolve it on the section rather than leave it to the case officer.
Many of Redlands's terraces sit in conservation areas — Redlands, Kendrick, Christchurch and Alexandra Road among them — where a side extension is no longer permitted development. Redlands ward sits inside Reading's HMO Article 4 direction, in force since 2013, which removes the automatic right to change a house (C3) to a small house in multiple occupation (C4) in this student-heavy area next to the University of Reading. We confirm the designation before a line is drawn.
Some single-storey side returns in Redlands 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 Reading Borough 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 Reading Borough 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 Reading Borough Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Redlands grants a solid share of householder applications, but as the borough's densest student-HMO belt it is where the Article 4 direction and the protection of remaining family houses shape most refusals. 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 Redlands, University (Whiteknights) and Erleigh Road, 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 large victorian and edwardian villas subdivided into flats and hmos, 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.
Converting family houses to further flats or student rooms is resisted and is frequently the deciding issue. 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 Reading Borough 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 Redlands side returns come up most often:

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