Two-storey extension drawings for Wroxham homes — bedroom above, living space below, drawn against the 3-metre projection and 7-metre boundary rules and to Broadland District Council's design guidance, delivered in days and revised free until your decision.
Broadland District Council granted 97% of the householder planning decisions it made in its latest published year — 10 points above the 87% England-wide householder average. Wroxham contains Belaugh, Salhouse, Salhouse BA Conservation Area conservation areas (Belaugh designated 1973), 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.
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. Wroxham carries at least one Article 4 direction, and conservation areas including Belaugh, Salhouse and Salhouse BA Conservation Area remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Wroxham is determined against an 8-week statutory target.
Belaugh (conservation area designated in 1973), Salhouse (conservation area designated in 2003), Salhouse BA (conservation area designated in 2003), Salhouse (conservation area designated in 2003), Wroxham BA (designated conservation area), Wroxham (designated conservation area), Wroxham (designated conservation area), Belaugh (civil parish within Wroxham), Rackheath (civil parish within Wroxham) and Salhouse (civil parish within Wroxham) — these are the Wroxham pockets our drawings cover most. Heritage designations here include Belaugh, Salhouse, Salhouse BA Conservation Area, Salhouse Conservation Area, Wroxham BA Conservation Area, Wroxham Conservation Area and Wroxham Conservation Area. Broadland District Council weighs each proposal against Broadland District Council's development plan and the design policies it applies to householder applications, where the 2,900 homes here are 14% 1955-1964, 10% 1973-1982, 9% pre-1900, which is what sets the realistic roof and rear-projection options. On roofs the borough is shallow gabled roofs typical of that period's building and shallow trussed roofs typical of 1970s building, over late-1950s and early-1960s houses (14% of 2,900 homes), 1970s and early-1980s houses (10%) and Victorian and earlier houses (9%).
Wroxham's designated heritage is specific, and it is the first thing we check against your address: Belaugh (conservation area designated in 1973), Salhouse (conservation area designated in 2003), Salhouse BA (conservation area designated in 2003), Salhouse (conservation area designated in 2003), Wroxham BA (designated conservation area), Wroxham (designated conservation area) and Wroxham (designated conservation area). Inside those boundaries permitted development is curtailed and Broadland 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, Wroxham takes in Belaugh, Rackheath and Salhouse. Broadland District Council has 28 recorded Article 4 directions — check the address before assuming PD applies in Wroxham.
On stock, Wroxham is late-1950s and early-1960s houses (14% of 2,900 homes), 1970s and early-1980s houses (10%) and Victorian and earlier houses (9%) — which is why shallow gabled roofs typical of that period's building and shallow trussed roofs typical of 1970s building govern what a loft or rear projection can realistically be. Broadland District Council decided 470 householder applications in the latest published year and granted 97%, with 68% issued inside the eight-week target. Those are the numbers our drawings are prepared against.
The full build-period split for Wroxham runs pre-1900 9% (260 homes), 1900-1918 1% (40 homes), 1919-1929 4% (110 homes), 1930-1939 4% (130 homes), 1945-1954 5% (150 homes), 1955-1964 14% (420 homes), 1965-1972 6% (160 homes), 1973-1982 10% (280 homes), 1983-1992 5% (150 homes), 1993-1999 9% (250 homes) and 2000-2008 8% (230 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.
Broadland District Council also decides for Aylsham, Eynesford, Hellesdon North West, Marshes, Plumstead and Coltishall, so a decision in Wroxham 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 Area centred on the Market Place, Broads Authoriity Holly Lodge, Broads Authority and Broads Authority Conservation Area. 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.

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. Wroxham is largely late-1950s and early-1960s houses (14% of 2,900 homes), 1970s and early-1980s houses (10%) and Victorian and earlier houses (9%), and shallow gabled roofs typical of that period's building and shallow trussed roofs typical of 1970s 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.
Wroxham contains Belaugh, Salhouse, Salhouse BA Conservation Area conservation areas (Belaugh designated 1973), so materials, fenestration and roof form are assessed against the appraisal. Broadland District Council has 28 recorded Article 4 directions — check the address before assuming PD applies in Wroxham.
Some two-storey rear extensions are permitted development. You will need a full application to Broadland 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 Broadland District Council checks first — then submit a validation-complete pack.
Below is Broadland District Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Broadland District Council granted 97% of its householder applications in the year to 31 March 2026, and Belaugh 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 Belaugh, Salhouse and Salhouse BA, 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 late-1950s and early-1960s houses (14% of 2,900 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 2,900 homes here are 14% 1955-1964, 10% 1973-1982, 9% pre-1900, 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.

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