Side-return infill drawings for St Neots Eynesbury terraces — the glazed extension that fills the redundant side alley and opens up the kitchen, drawn to Huntingdonshire District Council's guidance, delivered in days and revised free until your decision, with a free approval-odds check first.
Huntingdonshire District Council granted 95% of the householder planning decisions it made in its latest published year — 8 points above the 87% England-wide householder average. St Neots Eynesbury contains the SAINT NEOTS INCL EYNESBURY AND EATON SOCON AND EATON FORD 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 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. St Neots Eynesbury carries at least one Article 4 direction, and conservation areas including SAINT NEOTS INCL EYNESBURY AND EATON SOCON AND EATON FORD remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in St Neots Eynesbury is determined against an 8-week statutory target.
SAINT NEOTS INCL EYNESBURY AND EATON SOCON AND EATON FORD (designated conservation area) and St. Neots (civil parish within St Neots Eynesbury) — these are the St Neots Eynesbury pockets our drawings cover most. Heritage designations here include SAINT NEOTS INCL EYNESBURY AND EATON SOCON AND EATON FORD. Huntingdonshire District Council weighs each proposal against the adopted Huntingdonshire local plan and Huntingdonshire District Council's design guidance for householder work, where the 6,050 homes here are 26% 1965-1972, 18% 1983-1992, 14% 2000-2008, which is what sets the realistic roof and rear-projection options. On roofs the borough is shallow-pitched roofs and integral garages typical of that period's building and trussed-rafter roofs typical of 1980s building, over late-1960s and early-1970s houses (26% of 6,050 homes), 1980s estate houses (18%) and 2000s houses and apartments (14%).
St Neots Eynesbury's designated heritage is specific, and it is the first thing we check against your address: SAINT NEOTS INCL EYNESBURY AND EATON SOCON AND EATON FORD (designated conservation area). Inside those boundaries permitted development is curtailed and Huntingdonshire District 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, St Neots Eynesbury takes in St. Neots. Huntingdonshire District Council has 6 recorded Article 4 directions, removing permitted development for painting the exterior — check the address before assuming PD applies in St Neots Eynesbury.
On stock, St Neots Eynesbury is late-1960s and early-1970s houses (26% of 6,050 homes), 1980s estate houses (18%) and 2000s houses and apartments (14%) — which is why shallow-pitched roofs and integral garages typical of that period's building and trussed-rafter roofs typical of 1980s building govern what a loft or rear projection can realistically be. Huntingdonshire District Council decided 512 householder applications in the latest published year and granted 95%, with 55% issued inside the eight-week target. Those are the numbers our drawings are prepared against.
The full build-period split for St Neots Eynesbury runs pre-1900 7% (420 homes), 1900-1918 1% (70 homes), 1919-1929 2% (120 homes), 1930-1939 2% (110 homes), 1945-1954 1% (90 homes), 1955-1964 9% (550 homes), 1965-1972 26% (1,560 homes), 1973-1982 3% (190 homes), 1983-1992 18% (1,070 homes), 1993-1999 6% (380 homes) and 2000-2008 14% (860 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.
Huntingdonshire District Council also decides for Alconbury, Brampton, Buckden, Fenstanton, Great Paxton, Great Staughton, Huntingdon East and Huntingdon North, so a decision in St Neots Eynesbury 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 1 Galley Hill, Hemingford Grey, Poultry Houses, High Bank, Hill View, Spaldwick Road, Stow Longa, Land East Of Crosshall Road, St Neots and Oundle Road, Alwalton. 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 St Neots Eynesbury has the stock for it — the borough is built largely from late-1960s and early-1970s houses (26% of 6,050 homes), 1980s estate houses (18%) and 2000s houses and apartments (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. Huntingdonshire District Council judges the infill against the adopted Huntingdonshire local plan and Huntingdonshire District Council's design guidance for householder work, 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. St Neots Eynesbury contains the SAINT NEOTS INCL EYNESBURY AND EATON SOCON AND EATON FORD 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 St Neots Eynesbury's terraces sit in conservation areas — SAINT NEOTS INCL EYNESBURY AND EATON SOCON AND EATON FORD among them — where a side extension is no longer permitted development. Huntingdonshire District Council has 6 recorded Article 4 directions, removing permitted development for painting the exterior — check the address before assuming PD applies in St Neots Eynesbury. We confirm the designation before a line is drawn.
Some single-storey side returns in St Neots Eynesbury 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 Huntingdonshire District 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 Huntingdonshire District 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 Huntingdonshire District Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Huntingdonshire District Council granted 95% of its householder applications in the year to 31 March 2026, and SAINT NEOTS INCL EYNESBURY AND EATON SOCON AND EATON FORD 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 SAINT NEOTS INCL EYNESBURY AND EATON SOCON AND EATON FORD and St. Neots, 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 late-1960s and early-1970s houses (26% of 6,050 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 6,050 homes here are 26% 1965-1972, 18% 1983-1992, 14% 2000-2008, 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 Huntingdonshire District 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 St Neots Eynesbury side returns come up most often:

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