Two-storey extension drawings for Newbury Clay Hill homes — bedroom above, living space below, drawn against the 3-metre projection and 7-metre boundary rules and to West Berkshire Council's design guidance, delivered in days and revised free until your decision.
West Berkshire Council granted 93% of the householder planning decisions it made in its latest published year — 6 points above the 87% England-wide householder average. Newbury Clay Hill contains the Shaw Road and Crescent conservation area (Shaw Road and Crescent designated 1981), 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.
Class A and Class B set the thresholds — a rear dormer to 40m³ on a terrace or 50m³ on a semi or detached, and a single-storey rear extension to 3m on a terrace or 4m on a detached house — beyond which West Berkshire Council needs a full application. Newbury Clay Hill carries at least one Article 4 direction, and conservation areas including Shaw Road and Crescent remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Newbury Clay Hill is determined against an 8-week statutory target.
Shaw Road and Crescent (conservation area designated in 1981), Cold Ash (civil parish within Newbury Clay Hill) and Newbury (civil parish within Newbury Clay Hill) — these are the Newbury Clay Hill pockets our drawings cover most. Heritage designations here include Shaw Road and Crescent. West Berkshire Council weighs each proposal against West Berkshire Council's development plan and the design policies it applies to householder applications, where the 3,990 homes here are 16% 1973-1982, 15% 2000-2008, 13% 1955-1964, 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 2000s building, over 1970s and early-1980s houses (16% of 3,990 homes), 2000s houses and apartments (15%) and late-1950s and early-1960s houses (13%).
Heritage designation is the single biggest variable in Newbury Clay Hill, and it is address-specific: Shaw Road and Crescent (conservation area designated in 1981). Inside those boundaries permitted development is curtailed and West Berkshire 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, Newbury Clay Hill takes in Cold Ash and Newbury. West Berkshire Council has 9 recorded Article 4 directions — check the address before assuming PD applies in Newbury Clay Hill.
On stock, Newbury Clay Hill is 1970s and early-1980s houses (16% of 3,990 homes), 2000s houses and apartments (15%) and late-1950s and early-1960s houses (13%) — which is why shallow trussed roofs typical of 1970s building and trussed-rafter roofs typical of 2000s building govern what a loft or rear projection can realistically be. West Berkshire Council decided 606 householder applications in the latest published year and granted 93%, with 57% issued inside the eight-week target. We work from the council's own published record.
The full build-period split for Newbury Clay Hill runs pre-1900 5% (210 homes), 1900-1918 1% (40 homes), 1919-1929 2% (80 homes), 1930-1939 5% (180 homes), 1945-1954 3% (110 homes), 1955-1964 13% (510 homes), 1965-1972 11% (420 homes), 1973-1982 16% (650 homes), 1983-1992 9% (340 homes), 1993-1999 11% (440 homes) and 2000-2008 15% (580 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.
West Berkshire Council also decides for Aldermaston, Basildon, Bradfield, Chieveley & Cold Ash, Downlands, Hungerford & Kintbury, Lambourn and Newbury Greenham, so a decision in Newbury Clay Hill 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 Fords Farm Estate, Land Fronting 1085-1107 Oxford Road, Tilehurst, Land at East Garston and Land at Theobald Drive, Tilehurst. 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. Newbury Clay Hill is largely 1970s and early-1980s houses (16% of 3,990 homes), 2000s houses and apartments (15%) and late-1950s and early-1960s houses (13%), and shallow trussed roofs typical of 1970s building and trussed-rafter roofs typical of 2000s 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.
Newbury Clay Hill contains the Shaw Road and Crescent conservation area (Shaw Road and Crescent designated 1981), so materials, fenestration and roof form are assessed against the appraisal.

Some two-storey rear extensions are permitted development. You will need a full application to West Berkshire 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 West Berkshire Council checks first — then submit a validation-complete pack.
Below is West Berkshire Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. West Berkshire Council granted 93% of its householder applications in the year to 31 March 2026, and Shaw Road and Crescent 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 Shaw Road and Crescent, Cold Ash and Newbury, 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 (16% of 3,990 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 3,990 homes here are 16% 1973-1982, 15% 2000-2008, 13% 1955-1964, 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 Newbury Clay Hill. A few of the areas where they come up most often:
Two storey extension drawings for Shaw Road and Crescent — conservation area designated in 1981 — dimensioned against the 3m and 7m limits and drawn to West Berkshire Council's guidance.
Two storey extension drawings for Cold Ash — civil parish within Newbury Clay Hill — dimensioned against the 3m and 7m limits and drawn to West Berkshire Council's guidance.
Two storey extension drawings for Newbury — civil parish within Newbury Clay Hill — dimensioned against the 3m and 7m limits and drawn to West Berkshire 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 West Berkshire 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 West Berkshire Council validates and decides two-storey applications.
Send us your Newbury Clay Hill postcode and garden depth. We measure the 7-metre boundary rule against your plot, confirm designation status, and score your odds against live West Berkshire 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 West Berkshire 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 Newbury Clay Hill, the 7-metre rule is what most commonly forces a full application to West Berkshire 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 Newbury Clay Hill gardens this is decisive, and we measure it on survey before any design work rather than discovering it at validation. West Berkshire Council is the decision-maker.
Not under permitted development — two-storey side extensions always need a full application to West Berkshire 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 Newbury Clay Hill 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 Newbury Clay Hill address specifically. West Berkshire 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 West Berkshire Council's planning decision, so we flag the notice period early and detail the junction on the drawings. This applies to your Newbury Clay Hill 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 Newbury Clay Hill address specifically. West Berkshire Council is the decision-maker.
