Side-return infill drawings for Battle 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. Selective and additional licensing shapes the shared-housing stock even outside the borough's HMO Article 4 area, which is where a policy-literate drawing pack earns its keep. Its dominant Georgian (1714–1837) and Victorian (1837–1901) 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 Castle Hill/Russell Street/Oxford Road and Downshire Square those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Battle is determined against an 8-week statutory target.
Oxford Road (long red-brick Victorian terraces along the western high street), Battle (dense terraced streets around the old Battle farm and hospital site), West Reading (Victorian terraces heavily subdivided into flats and rentals), Castle Hill (grand Victorian houses in the Castle Hill/Russell Street conservation area), Prospect Street (terraces and parades on the ground rising west of the centre) and Downshire Square (Regency and Victorian villas at the district's southern edge) — these are the Battle pockets our drawings cover most. Heritage designations here include Castle Hill/Russell Street/Oxford Road and Downshire Square. Reading Borough Council weighs each proposal against the Reading Borough Local Plan (2019), where the loss of family terraces to further flat and rented conversion is a recurring issue along the Oxford Road. Much of Battle and West Reading is already converted flats and HMOs, which carry no householder permitted-development rights.. On roofs the borough is pitched and gabled roofs on the Oxford Road terraces and valley roofs behind the larger Victorian houses, over Victorian red-brick terraces along the Oxford Road, converted flats and HMOs on the terraced streets and larger Victorian houses toward Downshire Square.
The side return is the classic terrace fix, and Battle has the stock for it — the borough is built largely from Victorian red-brick terraces along the Oxford Road, converted flats and HMOs on the terraced streets and larger Victorian houses toward Downshire Square, 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. Selective and additional licensing shapes the shared-housing stock even outside the borough's HMO Article 4 area, so we resolve it on the section rather than leave it to the case officer.
Many of Battle's terraces sit in conservation areas — Castle Hill/Russell Street/Oxford Road and Downshire Square among them — where a side extension is no longer permitted development. Battle ward is not covered by Reading's HMO Article 4 direction, but the council has run selective and additional licensing here, so shared-housing standards bite even where planning permitted-development rights still apply outside the Castle Hill conservation area. We confirm the designation before a line is drawn.
Some single-storey side returns in Battle 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. Battle approves most householder applications, but its heavily subdivided Oxford Road terraces and the Castle Hill conservation area are where flat conversions and design set the harder cases. 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 Oxford Road, Battle and West Reading, 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 red-brick terraces along the oxford road, 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 loss of family terraces to further flat and rented conversion is a recurring issue along the Oxford Road. 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 Battle side returns come up most often:

Whether a side return in Battle 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 Castle Hill/Russell Street/Oxford Road and Downshire Square, 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 Battle 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 Battle 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 Castle Hill/Russell Street/Oxford Road and Downshire Square, 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. Battle'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 Battle 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 Battle address specifically.
A householder planning application in Battle 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 Battle 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.
