Two-storey extension drawings for Kelsale & Yoxford homes — bedroom above, living space below, drawn against the 3-metre projection and 7-metre boundary rules and to East Suffolk Council's design guidance, delivered in days and revised free until your decision.
East Suffolk Council granted 95% of the householder planning decisions it made in its latest published year — 8 points above the 87% England-wide householder average. Kelsale & Yoxford contains Huntingfield, Peasenhall and Sibton, Yoxford conservation areas (Huntingfield designated 1988), so materials, fenestration and roof form are assessed against the appraisal, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901), interwar (1918–1939) and postwar (1945–1970) 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. In conservation areas such as Huntingfield, Peasenhall and Sibton and Yoxford those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Kelsale & Yoxford is determined against an 8-week statutory target.
Huntingfield (conservation area designated in 1988), Peasenhall and Sibton (conservation area designated in 1972), Yoxford (conservation area designated in 1973), Sibton (civil parish within Kelsale & Yoxford), Ubbeston (civil parish within Kelsale & Yoxford), Walpole (civil parish within Kelsale & Yoxford), Yoxford (civil parish within Kelsale & Yoxford), Heveningham (civil parish within Kelsale & Yoxford) and Huntingfield (civil parish within Kelsale & Yoxford) — these are the Kelsale & Yoxford pockets our drawings cover most. Heritage designations here include Huntingfield, Peasenhall and Sibton and Yoxford. East Suffolk Council weighs each proposal against the adopted East Suffolk local plan and East Suffolk Council's design guidance for householder work, where the 1,860 homes here are 42% pre-1900, 7% 1945-1954, 6% 1930-1939, which is what sets the realistic roof and rear-projection options. On roofs the borough is steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and simple gabled and hipped roofs typical of early postwar building, over Victorian and earlier houses (42% of 1,860 homes), early postwar houses (7%) and 1930s semi-detached and detached houses (6%).
What is permitted in Kelsale & Yoxford turns on designation first, so that is where we start: Huntingfield (conservation area designated in 1988), Peasenhall and Sibton (conservation area designated in 1972) and Yoxford (conservation area designated in 1973). Inside those boundaries permitted development is curtailed and East Suffolk 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, Kelsale & Yoxford takes in Sibton, Ubbeston, Walpole, Yoxford, Heveningham and Huntingfield. No Article 4 direction is recorded for East Suffolk Council, but Kelsale & Yoxford's 3 conservation areas still limit permitted development on those streets.
On stock, Kelsale & Yoxford is Victorian and earlier houses (42% of 1,860 homes), early postwar houses (7%) and 1930s semi-detached and detached houses (6%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and simple gabled and hipped roofs typical of early postwar building govern what a loft or rear projection can realistically be. East Suffolk Council decided 1,008 householder applications in the latest published year and granted 95%, with 60% issued inside the eight-week target. We draw to that record rather than to a national average.
The full build-period split for Kelsale & Yoxford runs pre-1900 42% (780 homes), 1900-1918 1% (10 homes), 1919-1929 1% (20 homes), 1930-1939 6% (120 homes), 1945-1954 7% (130 homes), 1955-1964 6% (120 homes), 1965-1972 4% (80 homes), 1973-1982 6% (120 homes), 1983-1992 4% (80 homes), 1993-1999 3% (50 homes) and 2000-2008 5% (100 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 Suffolk Council also decides for Beccles & Worlingham, Bungay & Wainford, Carlford & Fynn Valley, Deben, Eastern Felixstowe, Framlingham, Halesworth & Blything and Harbour & Normanston, so a decision in Kelsale & Yoxford 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.

Adding at first floor changes the question the case officer asks. A single-storey extension is judged mostly on daylight and garden loss; a two-storey extension is judged on overlooking, bulk against the neighbouring roofline, and whether it reads as part of the house or bolted onto it. Kelsale & Yoxford is largely Victorian and earlier houses (42% of 1,860 homes), early postwar houses (7%) and 1930s semi-detached and detached houses (6%), and steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and simple gabled and hipped roofs typical of early postwar building set what a matching roof actually means here.
The permitted-development route exists but is narrow: 3 metres of rear projection, a 7-metre stand-off from the rear boundary, eaves and ridge no higher than the original, and side-facing upper windows obscure-glazed and non-opening below 1.7 metres above floor level. Most two-storey schemes fail one of those, usually the 7-metre boundary rule on a shorter garden, and go in as a full application instead. We establish which route applies before designing, because it changes the drawing set.
Kelsale & Yoxford contains Huntingfield, Peasenhall and Sibton, Yoxford conservation areas (Huntingfield designated 1988), so materials, fenestration and roof form are assessed against the appraisal. No Article 4 direction is recorded for East Suffolk Council, but Kelsale & Yoxford's 3 conservation areas still limit permitted development on those streets.
Some two-storey rear extensions are permitted development. You will need a full application to East Suffolk Council if any of these apply:
We set the projection and boundary distance on the site plan, prove the roof-pitch match on the elevations, and specify obscure glazing on the side windows — the three things East Suffolk Council checks first — then submit a validation-complete pack.
Below is East Suffolk Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. East Suffolk Council granted 95% of its householder applications in the year to 31 March 2026, and Huntingfield shapes what is approved here. Two-storey schemes attract more neighbour comment than any other householder work, so the overlooking and daylight case has to be made on the drawings.

Across Huntingfield, Peasenhall and Sibton and Yoxford, the schemes that succeed set the first floor back from the ground floor, keep the ridge below the original, and treat the flank wall as blank or obscure-glazed. On victorian and earlier houses (42% of 1,860 homes), matching the eaves line matters more than matching the brick: an extension that carries the existing eaves through reads as original even in a different material.
The 1,860 homes here are 42% pre-1900, 7% 1945-1954, 6% 1930-1939, which is what sets the realistic roof and rear-projection options. We draw the 45-degree daylight test from the neighbour's nearest habitable window, show the window positions in section, and set out the steel and foundation implications early — a two-storey extension changes the load path, so the structural design and the planning design have to be developed together rather than in sequence.
We draw two-storey extensions across Kelsale & Yoxford. A few of the areas where they come up most often:
Two storey extension drawings for Huntingfield — conservation area designated in 1988 — dimensioned against the 3m and 7m limits and drawn to East Suffolk Council's guidance.
Two storey extension drawings for Peasenhall and Sibton — conservation area designated in 1972 — dimensioned against the 3m and 7m limits and drawn to East Suffolk Council's guidance.
Two storey extension drawings for Yoxford — conservation area designated in 1973 — dimensioned against the 3m and 7m limits and drawn to East Suffolk Council's guidance.
Two storey extension drawings for Sibton — civil parish within Kelsale & Yoxford — dimensioned against the 3m and 7m limits and drawn to East Suffolk Council's guidance.
Two storey extension drawings for Ubbeston — civil parish within Kelsale & Yoxford — dimensioned against the 3m and 7m limits and drawn to East Suffolk Council's guidance.
Two storey extension drawings for Walpole — civil parish within Kelsale & Yoxford — dimensioned against the 3m and 7m limits and drawn to East Suffolk Council's guidance.
The first-floor limits are tighter than the ground-floor ones. This is how the common cases compare.
| Scheme | Permitted development? | Deciding limit | What East Suffolk Council checks |
|---|---|---|---|
| Two-storey rear, 3m projection, 7m+ to boundary | Often yes | 3m projection / 7m boundary | Roof match, side-window glazing |
| Two-storey rear, under 7m to boundary | No — full application | Rear-boundary distance | Overlooking, daylight, garden loss |
| Two-storey side extension | No — full application | Side elevation | Gap to boundary, street rhythm |
| Two-storey wraparound | No — full application | Combined footprint | Bulk, massing, neighbour amenity |
| Any two-storey on designated land | No — full application | Designation | Character and appearance |

A fixed process built around how East Suffolk Council validates and decides two-storey applications.
Send us your Kelsale & Yoxford postcode and garden depth. We measure the 7-metre boundary rule against your plot, confirm designation status, and score your odds against live East Suffolk Council decisions.
We measure the original rear wall, eaves and ridge heights, garden depth and every neighbouring window that faces the site — the inputs the daylight and overlooking case is built from.
Chartered designers develop the two-storey addition to your brief with the roof and eaves resolved, and we coordinate the load path so the structural scheme and the planning scheme are the same building.
We submit the application, manage validation and case-officer queries, and revise the drawings free until East Suffolk Council issues its decision.
Often, but not always. A two-storey rear extension can be permitted development if it projects no more than 3 metres, sits at least 7 metres from the rear boundary, does not exceed the existing eaves and ridge, and has obscure-glazed non-opening side windows below 1.7 metres. In Kelsale & Yoxford, the 7-metre rule is what most commonly forces a full application to East Suffolk Council.
No part of a permitted-development two-storey rear extension may come within 7 metres of the boundary opposite the rear wall of the house. It exists to protect the neighbour behind you from being overlooked at first floor. On shorter Kelsale & Yoxford gardens this is decisive, and we measure it on survey before any design work rather than discovering it at validation. East Suffolk Council is the decision-maker.
Not under permitted development — two-storey side extensions always need a full application to East Suffolk Council. They are assessed on the gap to the boundary, whether the street's rhythm of spaces between houses survives, and whether the extension is subordinate to the original. Setting the first floor back from the front building line and down from the ridge is what usually makes the difference. This applies to your Kelsale & Yoxford address specifically.
Overlooking is the most common objection, and it is answerable on the drawings. We position habitable-room windows away from neighbouring gardens, obscure-glaze and fix shut anything on the flank below 1.7 metres, and show the sight lines in section. Where the geometry is tight, a rooflight or a high-level window gives the same daylight without the mutual overlooking that draws objections. This applies to your Kelsale & Yoxford address specifically. East Suffolk Council is the decision-maker.
Almost certainly. Excavating within 3 metres of a neighbouring structure and building on or up to the boundary both trigger the Party Wall etc. Act 1996, and a two-storey extension usually does both. It is entirely separate from East Suffolk Council's planning decision, so we flag the notice period early and detail the junction on the drawings. This applies to your Kelsale & Yoxford address specifically.
Yes. Adding a floor changes the load path from roof to foundation, so beams, padstones and foundation depths all need designing and calculating for building control. Planning and building regulations are separate consents, and the structural set is what building control assesses — we prepare both so the approved scheme is the buildable one. This applies to your Kelsale & Yoxford address specifically. East Suffolk Council is the decision-maker.
