Two-storey extension drawings for Allesley homes — bedroom above, living space below, drawn against the 3-metre projection and 7-metre boundary rules and to Coventry City Council's design guidance, delivered in days and revised free until your decision.
Coventry City Council granted 86% of the householder planning decisions it made in its latest published year — 1 point below the 87% England-wide householder average. The Coundon Wedge green belt around the village strictly limits new building and larger replacement dwellings on the rural edge, which is where a policy-literate drawing pack earns its keep. Its dominant interwar (1918–1939) 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 Allesley Village and Brownshill Green those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Allesley is determined against an 8-week statutory target.
Allesley Village (a conservation area of cottages and a medieval church core designated in 1968), Brownshill Green (a small conservation area of rural-edge cottages to the north), Allesley Park (post-war and 1960s suburban housing south of the village), Allesley Green (later detached and semi-detached estates toward the A45), Coundon Wedge (green-belt farmland separating the village from the built-up city) and Eastern Green fringe (interwar and post-war semis on the western edge) — these are the Allesley pockets our drawings cover most. Heritage designations here include Allesley Village and Brownshill Green. Coventry City Council weighs each proposal against the Coventry Local Plan (2017), where the Allesley Village conservation area protects its cottage scale, materials and church setting in fine grain. On roofs the borough is steep tiled and part-thatched roofs on the village cottages and hipped roofs on the interwar and post-war semis and detached homes, over historic village cottages and farmhouses, 1930s interwar semi-detached houses and post-war and later suburban detached homes.
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. Allesley is largely historic village cottages and farmhouses, 1930s interwar semi-detached houses and post-war and later suburban detached homes, and steep tiled and part-thatched roofs on the village cottages and hipped roofs on the interwar and post-war semis and detached homes 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.
The Coundon Wedge green belt around the village strictly limits new building and larger replacement dwellings on the rural edge. Allesley (Bablake ward) sits outside the wards named in Coventry's citywide HMO Article 4 direction, so the usual householder permitted-development rights still apply — though works within the Allesley Village and Brownshill Green conservation areas remain controlled.
Some two-storey rear extensions are permitted development. You will need a full application to Coventry City 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 Coventry City Council checks first — then submit a validation-complete pack.
Below is Coventry City Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Allesley approves most householder schemes, but the green-belt Coundon Wedge and the tightly-protected village conservation area are what constrain scale and siting on the rural edge. 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 Allesley Village, Brownshill Green and Allesley Park, 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 historic village cottages and farmhouses, 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 Allesley Village conservation area protects its cottage scale, materials and church setting in fine grain. 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 Allesley. A few of the areas where they come up most often:
Two storey extension drawings for Allesley Village — a conservation area of cottages and a medieval church core designated in 1968 — dimensioned against the 3m and 7m limits and drawn to Coventry City Council's guidance.
Two storey extension drawings for Brownshill Green — a small conservation area of rural-edge cottages to the north — dimensioned against the 3m and 7m limits and drawn to Coventry City Council's guidance.
Two storey extension drawings for Allesley Park — post-war and 1960s suburban housing south of the village — dimensioned against the 3m and 7m limits and drawn to Coventry City Council's guidance.
Two storey extension drawings for Allesley Green — later detached and semi-detached estates toward the A45 — dimensioned against the 3m and 7m limits and drawn to Coventry City Council's guidance.
Two storey extension drawings for Coundon Wedge — green-belt farmland separating the village from the built-up city — dimensioned against the 3m and 7m limits and drawn to Coventry City Council's guidance.
Two storey extension drawings for Eastern Green fringe — interwar and post-war semis on the western edge — dimensioned against the 3m and 7m limits and drawn to Coventry City 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 Coventry City 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 Coventry City Council validates and decides two-storey applications.
Send us your Allesley postcode and garden depth. We measure the 7-metre boundary rule against your plot, confirm designation status, and score your odds against live Coventry City 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 Coventry City 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 Allesley, the 7-metre rule is what most commonly forces a full application to Coventry City 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 Allesley gardens this is decisive, and we measure it on survey before any design work rather than discovering it at validation. Coventry City Council is the decision-maker.
Not under permitted development — two-storey side extensions always need a full application to Coventry City 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 Allesley 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 Allesley address specifically. Coventry City 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 Coventry City Council's planning decision, so we flag the notice period early and detail the junction on the drawings. This applies to your Allesley 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 Allesley address specifically. Coventry City Council is the decision-maker.
We quote each Allesley two-storey extension individually, because plot depth, roof form and structural complexity vary house to house, and send a fixed, no-obligation quote within one working day.
