Two-storey extension drawings for Heaton homes — bedroom above, living space below, drawn against the 3-metre projection and 7-metre boundary rules and to Newcastle City Council's design guidance, delivered in days and revised free until your decision.
Newcastle City Council granted 93% of the householder planning decisions it made in its latest published year — 6 points above the 87% England-wide householder average. The HMO Article 4 direction brings most house-to-HMO conversions in Heaton into the full planning system, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901), Edwardian (1901–1910) and interwar (1918–1939) housing stock sets the design brief on most streets.
Before permission is required, Class B allows 40m³ of added loft volume on a terrace and 50m³ on a semi or detached house, and Class A allows a 3m single-storey rear extension on a terrace or 4m on a detached house. Heaton carries at least one Article 4 direction, and conservation areas including Jesmond Dene and Lower Ouseburn Valley remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Heaton is determined against an 8-week statutory target.
Heaton (grid of Victorian terraces and Tyneside flats east of Jesmond), High Heaton (interwar semis and terraces toward Coast Road), Byker Bank / Ouseburn edge (terraces dropping to the Lower Ouseburn Valley conservation area), Heaton Park (Victorian streets framing the park and Jesmond Vale), Chillingham Road (Tyneside flats and shops along the Metro corridor) and Jesmond Vale (terraces beside the Ouseburn on the Jesmond Dene fringe) — these are the Heaton pockets our drawings cover most. Heritage designations here include Jesmond Dene and Lower Ouseburn Valley. Newcastle City Council weighs each proposal against the Newcastle Development Plan — the Core Strategy and Urban Core Plan for Gateshead and Newcastle upon Tyne (2015) and the Development and Allocations Plan (2020), where splitting or reconfiguring Tyneside flats is tested against the loss of family accommodation and shared amenity. Heaton is classic Tyneside-flat territory — pairs of self-contained upstairs and downstairs flats behind two front doors — and flats carry no householder permitted-development rights.. On roofs the borough is pitched slate gable roofs on the terraces and shallow pitched roofs behind the Tyneside-flat frontages, over Tyneside flats, dense Victorian and Edwardian terraces and converted period flats.
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. Heaton is largely Tyneside flats, dense Victorian and Edwardian terraces and converted period flats, and pitched slate gable roofs on the terraces and shallow pitched roofs behind the Tyneside-flat frontages 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 HMO Article 4 direction brings most house-to-HMO conversions in Heaton into the full planning system. Heaton is inside Newcastle's HMO Article 4 directions, so converting a family house to a small HMO (Class C3 to C4) needs planning permission — a control aimed squarely at the student and shared-house belt that runs through Heaton, Jesmond and Sandyford.
Some two-storey rear extensions are permitted development. You will need a full application to Newcastle 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 Newcastle City Council checks first — then submit a validation-complete pack.
Below is Newcastle City Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Newcastle approves most householder applications, but in Heaton the HMO Article 4 direction and the dense Tyneside-flat and terrace grain shape what can actually be built. 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 Heaton, High Heaton and Byker Bank / Ouseburn edge, 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 tyneside flats, 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.
Splitting or reconfiguring Tyneside flats is tested against the loss of family accommodation and shared amenity. 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 Heaton. A few of the areas where they come up most often:
Two storey extension drawings for Heaton — grid of Victorian terraces and Tyneside flats east of Jesmond — dimensioned against the 3m and 7m limits and drawn to Newcastle City Council's guidance.
Two storey extension drawings for High Heaton — interwar semis and terraces toward Coast Road — dimensioned against the 3m and 7m limits and drawn to Newcastle City Council's guidance.
Two storey extension drawings for Byker Bank / Ouseburn edge — terraces dropping to the Lower Ouseburn Valley conservation area — dimensioned against the 3m and 7m limits and drawn to Newcastle City Council's guidance.
Two storey extension drawings for Heaton Park — Victorian streets framing the park and Jesmond Vale — dimensioned against the 3m and 7m limits and drawn to Newcastle City Council's guidance.
Two storey extension drawings for Chillingham Road — Tyneside flats and shops along the Metro corridor — dimensioned against the 3m and 7m limits and drawn to Newcastle City Council's guidance.
Two storey extension drawings for Jesmond Vale — terraces beside the Ouseburn on the Jesmond Dene fringe — dimensioned against the 3m and 7m limits and drawn to Newcastle 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 Newcastle 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 Newcastle City Council validates and decides two-storey applications.
Send us your Heaton postcode and garden depth. We measure the 7-metre boundary rule against your plot, confirm designation status, and score your odds against live Newcastle 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 Newcastle 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 Heaton, the 7-metre rule is what most commonly forces a full application to Newcastle 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 Heaton gardens this is decisive, and we measure it on survey before any design work rather than discovering it at validation. Newcastle City Council is the decision-maker.
Not under permitted development — two-storey side extensions always need a full application to Newcastle 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 Heaton 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 Heaton address specifically. Newcastle 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 Newcastle City Council's planning decision, so we flag the notice period early and detail the junction on the drawings. This applies to your Heaton 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 Heaton address specifically. Newcastle City Council is the decision-maker.
We quote each Heaton 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.
