Two-storey extension drawings for South West Holderness homes — bedroom above, living space below, drawn against the 3-metre projection and 7-metre boundary rules and to East Riding of Yorkshire Council's design guidance, delivered in days and revised free until your decision.
East Riding of Yorkshire Council granted 92% of the householder planning decisions it made in its latest published year — 5 points above the 87% England-wide householder average. South West Holderness contains Hedon, Hedon Haven, Paull conservation areas (Hedon designated 1968), so materials, fenestration and roof form are assessed against the appraisal, which is where a policy-literate drawing pack earns its keep. Its mixed housing stock sets the design brief street by street.
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. South West Holderness carries at least one Article 4 direction, and conservation areas including Hedon, Hedon Haven and Paull remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in South West Holderness is determined against an 8-week statutory target.
Hedon (conservation area designated in 1968), Hedon Haven (conservation area designated in 1992), Paull (conservation area designated in 1991), Preston (conservation area designated in 1991), Hedon (civil parish within South West Holderness), Paull (civil parish within South West Holderness), Preston (civil parish within South West Holderness) and Thorngumbald (civil parish within South West Holderness) — these are the South West Holderness pockets our drawings cover most. Heritage designations here include Hedon, Hedon Haven, Paull and Preston. East Riding of Yorkshire Council weighs each proposal against East Riding of Yorkshire Council's adopted local plan and its householder design guidance, where the 6,710 homes here are 20% 1973-1982, 14% 1983-1992, 12% 2000-2008, which is what sets the realistic roof and rear-projection options. On roofs the borough is shallow trussed roofs typical of 1970s building and trussed-rafter roofs typical of 1980s building, over 1970s and early-1980s houses (20% of 6,710 homes), 1980s estate houses (14%) and 2000s houses and apartments (12%).
Before anything is drawn we check your address against the designations that apply in South West Holderness: Hedon (conservation area designated in 1968), Hedon Haven (conservation area designated in 1992), Paull (conservation area designated in 1991) and Preston (conservation area designated in 1991). Inside those boundaries permitted development is curtailed and East Riding of Yorkshire 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, South West Holderness takes in Hedon, Paull, Preston and Thorngumbald. East Riding of Yorkshire Council has 11 recorded Article 4 directions, removing permitted development for rear and side extensions — check the address before assuming PD applies in South West Holderness.
On stock, South West Holderness is 1970s and early-1980s houses (20% of 6,710 homes), 1980s estate houses (14%) and 2000s houses and apartments (12%) — which is why shallow trussed roofs typical of 1970s building and trussed-rafter roofs typical of 1980s building govern what a loft or rear projection can realistically be. East Riding of Yorkshire Council decided 830 householder applications in the latest published year and granted 92%, with 95% issued inside the eight-week target. That decision record, not a national figure, is what we design to.
The full build-period split for South West Holderness runs pre-1900 8% (510 homes), 1900-1918 2% (120 homes), 1919-1929 2% (110 homes), 1930-1939 6% (390 homes), 1945-1954 4% (290 homes), 1955-1964 11% (710 homes), 1965-1972 10% (670 homes), 1973-1982 20% (1,310 homes), 1983-1992 14% (920 homes), 1993-1999 9% (610 homes) and 2000-2008 12% (810 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 Riding of Yorkshire Council also decides for Beverley Rural, Bridlington North, Bridlington South, Dale, Driffield and Rural, East Wolds and Coastal, Goole South and Hessle, so a decision in South West Holderness 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 Alpine Villa (Beck Cottage), Atwick, Atwick Hall, Atwick, Clifton House, Atwick and Green View, Atwick. 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. South West Holderness is largely 1970s and early-1980s houses (20% of 6,710 homes), 1980s estate houses (14%) and 2000s houses and apartments (12%), and shallow trussed roofs typical of 1970s building and trussed-rafter roofs typical of 1980s 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.
South West Holderness contains Hedon, Hedon Haven, Paull conservation areas (Hedon designated 1968), so materials, fenestration and roof form are assessed against the appraisal. East Riding of Yorkshire Council has 11 recorded Article 4 directions, removing permitted development for rear and side extensions — check the address before assuming PD applies in South West Holderness.
Some two-storey rear extensions are permitted development. You will need a full application to East Riding of Yorkshire 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 Riding of Yorkshire Council checks first — then submit a validation-complete pack.
Below is East Riding of Yorkshire Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. East Riding of Yorkshire Council granted 92% of its householder applications in the year to 31 March 2026, and Hedon 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 Hedon, Hedon Haven and Paull, 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 1970s and early-1980s houses (20% of 6,710 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 6,710 homes here are 20% 1973-1982, 14% 1983-1992, 12% 2000-2008, 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 South West Holderness. A few of the areas where they come up most often:

Two storey extension drawings for Paull — civil parish within South West Holderness — dimensioned against the 3m and 7m limits and drawn to East Riding of Yorkshire 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 Riding of Yorkshire 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 Riding of Yorkshire Council validates and decides two-storey applications.
Send us your South West Holderness postcode and garden depth. We measure the 7-metre boundary rule against your plot, confirm designation status, and score your odds against live East Riding of Yorkshire 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 Riding of Yorkshire 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 South West Holderness, the 7-metre rule is what most commonly forces a full application to East Riding of Yorkshire 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 South West Holderness gardens this is decisive, and we measure it on survey before any design work rather than discovering it at validation. East Riding of Yorkshire Council is the decision-maker.
Not under permitted development — two-storey side extensions always need a full application to East Riding of Yorkshire 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 South West Holderness 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 South West Holderness address specifically. East Riding of Yorkshire 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 Riding of Yorkshire Council's planning decision, so we flag the notice period early and detail the junction on the drawings. This applies to your South West Holderness 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 South West Holderness address specifically. East Riding of Yorkshire Council is the decision-maker.
