Two-storey extension drawings for Stour Valley South homes — bedroom above, living space below, drawn against the 3-metre projection and 7-metre boundary rules and to Braintree District Council's design guidance, delivered in days and revised free until your decision.
Braintree District Council granted 92% of the householder planning decisions it made in its latest published year — 5 points above the 87% England-wide householder average. Stour Valley South contains Bulmer, Bures Hamlet conservation areas (Bulmer designated 1989), 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) and postwar (1945–1970) housing stock sets the design brief on most streets.
The permitted-development ceilings are fixed: 40m³ of new roof volume for a terraced loft and 50m³ for a semi or detached house under Class B, plus a 3m single-storey rear extension on a terrace or 4m on a detached house under Class A. In conservation areas such as Bulmer and Bures Hamlet those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Stour Valley South is determined against an 8-week statutory target.
Bulmer (conservation area designated in 1989), Bures Hamlet (conservation area designated in 1969), Wickham St. Paul (civil parish within Stour Valley South), Bulmer (civil parish within Stour Valley South), Bures Hamlet (civil parish within Stour Valley South), Gestingthorpe (civil parish within Stour Valley South), Alphamstone (civil parish within Stour Valley South) and Great Henny (civil parish within Stour Valley South) — these are the Stour Valley South pockets our drawings cover most. Heritage designations here include Bulmer and Bures Hamlet. Braintree District Council weighs each proposal against Braintree District Council's adopted local plan and its householder design guidance, where the 1,690 homes here are 36% pre-1900, 13% 1965-1972, 8% 1973-1982, 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 shallow-pitched roofs and integral garages typical of that period's building, over Victorian and earlier houses (36% of 1,690 homes), late-1960s and early-1970s houses (13%) and 1970s and early-1980s houses (8%).
Before anything is drawn we check your address against the designations that apply in Stour Valley South: Bulmer (conservation area designated in 1989) and Bures Hamlet (conservation area designated in 1969). Inside those boundaries permitted development is curtailed and Braintree 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, Stour Valley South takes in Wickham St. Paul, Bulmer, Bures Hamlet, Gestingthorpe, Alphamstone and Great Henny. No Article 4 direction is recorded for Braintree District Council, but Stour Valley South's 2 conservation areas still limit permitted development on those streets.
On stock, Stour Valley South is Victorian and earlier houses (36% of 1,690 homes), late-1960s and early-1970s houses (13%) and 1970s and early-1980s houses (8%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and shallow-pitched roofs and integral garages typical of that period's building govern what a loft or rear projection can realistically be. Braintree District Council decided 431 householder applications in the latest published year and granted 92%, with 78% issued inside the eight-week target. That decision record, not a national figure, is what we design to.
The full build-period split for Stour Valley South runs pre-1900 36% (600 homes), 1900-1918 2% (40 homes), 1919-1929 2% (30 homes), 1930-1939 5% (80 homes), 1945-1954 7% (110 homes), 1955-1964 4% (60 homes), 1965-1972 13% (220 homes), 1973-1982 8% (130 homes), 1983-1992 7% (120 homes), 1993-1999 6% (100 homes) and 2000-2008 4% (70 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.
Braintree District Council also decides for Bumpstead, Coggeshall, Hedingham, Kelvedon & Feering, Rayne, Stour Valley North, The Colnes and Three Fields, so a decision in Stour Valley South 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. Stour Valley South is largely Victorian and earlier houses (36% of 1,690 homes), late-1960s and early-1970s houses (13%) and 1970s and early-1980s houses (8%), and steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and shallow-pitched roofs and integral garages typical of that period's 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.
Stour Valley South contains Bulmer, Bures Hamlet conservation areas (Bulmer designated 1989), so materials, fenestration and roof form are assessed against the appraisal. No Article 4 direction is recorded for Braintree District Council, but Stour Valley South's 2 conservation areas still limit permitted development on those streets.
Some two-storey rear extensions are permitted development. You will need a full application to Braintree District 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 Braintree District Council checks first — then submit a validation-complete pack.
Below is Braintree District Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Braintree District Council granted 92% of its householder applications in the year to 31 March 2026, and Bulmer 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 Bulmer, Bures Hamlet and Wickham St. Paul, 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 (36% of 1,690 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 1,690 homes here are 36% pre-1900, 13% 1965-1972, 8% 1973-1982, 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.

The first-floor limits are tighter than the ground-floor ones. This is how the common cases compare.
| Scheme | Permitted development? | Deciding limit | What Braintree District 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 Braintree District Council validates and decides two-storey applications.
Send us your Stour Valley South postcode and garden depth. We measure the 7-metre boundary rule against your plot, confirm designation status, and score your odds against live Braintree District 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 Braintree District 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 Stour Valley South, the 7-metre rule is what most commonly forces a full application to Braintree District 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 Stour Valley South gardens this is decisive, and we measure it on survey before any design work rather than discovering it at validation. Braintree District Council is the decision-maker.
Not under permitted development — two-storey side extensions always need a full application to Braintree District 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 Stour Valley South 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 Stour Valley South address specifically. Braintree District 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 Braintree District Council's planning decision, so we flag the notice period early and detail the junction on the drawings. This applies to your Stour Valley South 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 Stour Valley South address specifically. Braintree District Council is the decision-maker.
