Two-storey extension drawings for Tewkesbury homes — bedroom above, living space below, drawn against the 3-metre projection and 7-metre boundary rules and to Tewkesbury Borough Council's design guidance, delivered in days and revised free until your decision.
Tewkesbury Borough Council granted 93% of the householder planning decisions it made in its latest published year — 6 points above the 87% England-wide householder average. Tewkesbury contains Bishop's Cleeve Conservation Area, Buckland Conservation Area, Dumbleton Conservation Area conservation areas (Bishop's Cleeve Conservation Area designated 1979), 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. Tewkesbury carries at least one Article 4 direction, and conservation areas including Bishop's Cleeve Conservation Area, Buckland Conservation Area and Dumbleton Conservation Area remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Tewkesbury is determined against an 8-week statutory target.
Bishop's Cleeve (conservation area designated in 1979), Buckland (conservation area designated in 1977), Dumbleton (conservation area designated in 2001), Great Washbourne (conservation area designated in 2001), Gretton (conservation area designated in 1975), Laverton (conservation area designated in 1977), Snowshill (conservation area designated in 1971), Stanton (conservation area designated in 1971), Cleeve St Michael's (ward of Tewkesbury), Tewkesbury South (ward of Tewkesbury), Winchcombe (ward of Tewkesbury), Cleeve Hill (ward of Tewkesbury) and Isbourne (ward of Tewkesbury) — these are the Tewkesbury pockets our drawings cover most. Heritage designations here include Bishop's Cleeve Conservation Area, Buckland Conservation Area, Dumbleton Conservation Area, Great Washbourne Conservation Area, Gretton Conservation Area, Laverton Conservation Area, Snowshill Conservation Area and Stanton Conservation Area. Tewkesbury Borough Council weighs each proposal against the adopted Tewkesbury local plan and Tewkesbury Borough Council's design guidance for householder work, where the 13,980 homes here are 11% pre-1900, 9% 1965-1972, 9% 1955-1964, 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 (11% of 13,980 homes), late-1960s and early-1970s houses (9%) and late-1950s and early-1960s houses (9%).
Before anything is drawn we check your address against the designations that apply in Tewkesbury: Bishop's Cleeve (conservation area designated in 1979), Buckland (conservation area designated in 1977), Dumbleton (conservation area designated in 2001), Great Washbourne (conservation area designated in 2001), Gretton (conservation area designated in 1975), Laverton (conservation area designated in 1977), Snowshill (conservation area designated in 1971) and Stanton (conservation area designated in 1971). Inside those boundaries permitted development is curtailed and Tewkesbury Borough 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, Tewkesbury takes in Cleeve St Michael's, Tewkesbury South, Winchcombe, Cleeve Hill and Isbourne. Tewkesbury Borough Council has 11 recorded Article 4 directions, removing permitted development for rear and side extensions and other roof alterations, including rooflights — check the address before assuming PD applies in the district.
On stock, Tewkesbury is Victorian and earlier houses (11% of 13,980 homes), late-1960s and early-1970s houses (9%) and late-1950s and early-1960s houses (9%) — 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. Tewkesbury Borough Council decided 380 householder applications in the latest published year and granted 93%, with 57% issued inside the eight-week target. That decision record, not a national figure, is what we design to.
The full build-period split for Tewkesbury runs pre-1900 3% (190 homes), 1900-1918 0% (30 homes), 1919-1929 0% (10 homes), 1930-1939 6% (350 homes), 1945-1954 3% (170 homes), 1955-1964 30% (1,850 homes), 1965-1972 33% (1,990 homes), 1973-1982 4% (260 homes), 1983-1992 5% (310 homes), 1993-1999 4% (220 homes) and 2000-2008 3% (170 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.
Tewkesbury Borough Council also decides for Cleeve St Michael's, Tewkesbury South, Winchcombe, Cleeve Hill and Isbourne, so a decision in Tewkesbury 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 Ashleworth Green Article 4 Direction, Buckland Article 4 Direction, Church End Twyning Article 4 Direction and Dumbleton Article 4 Direction. 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. Tewkesbury is largely Victorian and earlier houses (11% of 13,980 homes), late-1960s and early-1970s houses (9%) and late-1950s and early-1960s houses (9%), 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.
Tewkesbury contains Bishop's Cleeve Conservation Area, Buckland Conservation Area, Dumbleton Conservation Area conservation areas (Bishop's Cleeve Conservation Area designated 1979), so materials, fenestration and roof form are assessed against the appraisal. Tewkesbury Borough Council has 11 recorded Article 4 directions, removing permitted development for rear and side extensions and other roof alterations, including rooflights — check the address before assuming PD applies in the district.
Some two-storey rear extensions are permitted development. You will need a full application to Tewkesbury Borough 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 Tewkesbury Borough Council checks first — then submit a validation-complete pack.
Below is Tewkesbury Borough Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Tewkesbury Borough Council granted 93% of 380 householder decisions in the year to 31 March 2026, 57% of them inside eight weeks. 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 Bishop's Cleeve, Buckland and Dumbleton, 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 (11% of 13,980 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 13,980 homes here are 11% pre-1900, 9% 1965-1972, 9% 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 Tewkesbury. A few of the areas where they come up most often:
Two storey extension drawings for Bishop's Cleeve — conservation area designated in 1979 — dimensioned against the 3m and 7m limits and drawn to Tewkesbury Borough Council's guidance.
Two storey extension drawings for Buckland — conservation area designated in 1977 — dimensioned against the 3m and 7m limits and drawn to Tewkesbury Borough Council's guidance.
Two storey extension drawings for Dumbleton — conservation area designated in 2001 — dimensioned against the 3m and 7m limits and drawn to Tewkesbury Borough Council's guidance.
Two storey extension drawings for Great Washbourne — conservation area designated in 2001 — dimensioned against the 3m and 7m limits and drawn to Tewkesbury Borough Council's guidance.
Two storey extension drawings for Gretton — conservation area designated in 1975 — dimensioned against the 3m and 7m limits and drawn to Tewkesbury Borough Council's guidance.
Two storey extension drawings for Laverton — conservation area designated in 1977 — dimensioned against the 3m and 7m limits and drawn to Tewkesbury Borough 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 Tewkesbury Borough 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 Tewkesbury Borough Council validates and decides two-storey applications.
Send us your Tewkesbury postcode and garden depth. We measure the 7-metre boundary rule against your plot, confirm designation status, and score your odds against live Tewkesbury Borough 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 Tewkesbury Borough 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 Tewkesbury, the 7-metre rule is what most commonly forces a full application to Tewkesbury Borough 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 Tewkesbury gardens this is decisive, and we measure it on survey before any design work rather than discovering it at validation. Tewkesbury Borough Council is the decision-maker.
Not under permitted development — two-storey side extensions always need a full application to Tewkesbury Borough 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.
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 Tewkesbury address specifically. Tewkesbury Borough 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 Tewkesbury Borough Council's planning decision, so we flag the notice period early and detail the junction on the drawings.
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 Tewkesbury address specifically. Tewkesbury Borough Council is the decision-maker.
