Side-return infill drawings for Hove terraces — the glazed extension that fills the redundant side alley and opens up the kitchen, drawn to Brighton & Hove City Council's guidance, delivered in days and revised free until your decision, with a free approval-odds check first.
Brighton & Hove City Council granted 89% of the householder planning decisions it made in its latest published year — 2 points above the 87% England-wide householder average. The Regency and early-Victorian stucco frontages of Brunswick and the seafront squares are protected in fine grain, down to render lines, railings and glazing, which is where a policy-literate drawing pack earns its keep. Its dominant Georgian (1714–1837), Victorian (1837–1901), Edwardian (1901–1910) and interwar (1918–1939) housing stock sets the design brief on most streets.
Class A and Class B set the thresholds — a rear dormer to 40m³ on a terrace or 50m³ on a semi or detached, and a single-storey rear extension to 3m on a terrace or 4m on a detached house — beyond which Brighton & Hove City Council needs a full application. Hove carries at least one Article 4 direction, and conservation areas including Old Hove, Brunswick Town and The Avenues remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Hove is determined against an 8-week statutory target.
Brunswick Town (Charles Busby's grand twin-terrace Regency estate off the seafront), The Avenues (wide Victorian streets of 1871–1901 villas between Church Road and the sea), Cliftonville (mid-Victorian Italianate villas and large Tudorbethan houses), Old Hove (the early stucco terraces around Brunswick and Adelaide Crescent), Poets' Corner (dense late-Victorian bay-fronted terraces north of Portland Road) and West Blatchington (interwar semi-detached suburbia on the downland fringe) — these are the Hove pockets our drawings cover most. Heritage designations here include Old Hove, Brunswick Town, The Avenues, Cliftonville, The Willett Estate and Sackville Gardens. Brighton & Hove City Council weighs each proposal against Brighton & Hove City Plan (Parts One 2016 and Two 2022) and the relevant SPDs, where seafront and set-piece square frontages attract the city's tightest design scrutiny, so alterations are kept behind the historic building line. Much of Brunswick Town, Old Hove and the Avenues is subdivided into flats and maisonettes, which carry no householder permitted-development rights of their own.. On roofs the borough is butterfly and valley roofs concealed behind the terrace parapets, mansard roofs on the taller stucco streets and hipped roofs on the interwar and villa stock, over Regency stucco terraces and set-piece squares, Victorian and Edwardian bay-fronted terraces, Italianate and Tudorbethan villas and interwar semi-detached houses.
The side return is the classic terrace fix, and Hove has the stock for it — the borough is built largely from Regency stucco terraces and set-piece squares, Victorian and Edwardian bay-fronted terraces, Italianate and Tudorbethan villas and interwar semi-detached houses, 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. Brighton & Hove City Council judges the infill against Brighton & Hove City Plan (Parts One 2016 and Two 2022) and the relevant SPDs, 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 Regency and early-Victorian stucco frontages of Brunswick and the seafront squares are protected in fine grain, down to render lines, railings and glazing, so we resolve it on the section rather than leave it to the case officer.
Many of Hove's terraces sit in conservation areas — Old Hove, Brunswick Town, The Avenues, Cliftonville, The Willett Estate and Sackville Gardens among them — where a side extension is no longer permitted development. Hove sits inside Brighton & Hove's city-wide Article 4 direction for small houses in multiple occupation, and separate conservation-area Article 4s in the Brunswick Town and Avenues estates remove permitted-development rights for works — from windows to front boundary walls — that would be automatic on an unprotected street. We confirm the designation before a line is drawn.
Some single-storey side returns in Hove 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 Brighton & Hove 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 Brighton & Hove 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 Brighton & Hove City Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Brighton & Hove grants the large majority of householder applications city-wide, but in Hove the Regency conservation coverage and the protected seafront squares set close limits on what roofs, windows and front alterations can do. 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 Brunswick Town, The Avenues and Cliftonville, 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 regency stucco terraces and set-piece squares, 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.
Seafront and set-piece square frontages attract the city's tightest design scrutiny, so alterations are kept behind the historic building line. 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 Brighton & Hove 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 Hove side returns come up most often:

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