Two-storey extension drawings for Epping Forest homes — bedroom above, living space below, drawn against the 3-metre projection and 7-metre boundary rules and to Epping Forest District Council's design guidance, delivered in days and revised free until your decision.
Epping Forest District Council granted 67% of the householder planning decisions it made in its latest published year — 20 points below the 87% England-wide householder average. Around 92 per cent of the district is Metropolitan Green Belt, the single biggest constraint on development, 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.
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. Epping Forest carries at least one Article 4 direction, and conservation areas including Epping, Loughton and Buckhurst Hill (St John's) remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Epping Forest is determined against an 8-week statutory target.
Epping (a historic market town with a High Street conservation area), Loughton (a Victorian and Edwardian forest-edge commuter suburb), Buckhurst Hill (St John's Victorian terraces and villas under Article 4 controls), Theydon Bois (a Green Belt village around a green on the Central line), Chipping Ongar (a historic market town with over a hundred listed structures) and Waltham Abbey (a historic abbey town with a medieval core) — these are the Epping Forest pockets our drawings cover most. Heritage designations here include Epping, Loughton, Buckhurst Hill (St John's), Chipping Ongar, Theydon Bois and Waltham Abbey. Epping Forest District Council weighs each proposal against the Epping Forest District Local Plan 2011–2033 (adopted March 2023), where the Epping Forest Special Area of Conservation drives strict control on top of extensive conservation-area coverage. Flat-conversion pressure is far lower than in the adjacent London boroughs; the district is dominated by houses, though converted flats still carry no householder permitted-development rights.. On roofs the borough is pitched tile and slate roofs on the Victorian villas and terraces and gabled roofs on the older village cottages, over Victorian villas and terraces in the Loughton and Buckhurst Hill commuter-railway suburbs, larger detached and interwar houses, green-belt village vernacular and medieval and period stock in the market-town cores.
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. Epping Forest is largely Victorian villas and terraces in the Loughton and Buckhurst Hill commuter-railway suburbs, larger detached and interwar houses, green-belt village vernacular and medieval and period stock in the market-town cores, and pitched tile and slate roofs on the Victorian villas and terraces and gabled roofs on the older village cottages 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.
Around 92 per cent of the district is Metropolitan Green Belt, the single biggest constraint on development. The district has Article 4 directions at Staples Road and York Hill in Loughton, and has consulted on a further direction for the St John's conservation area in Buckhurst Hill, removing permitted-development rights over Victorian terraces and villas.
Some two-storey rear extensions are permitted development. You will need a full application to Epping Forest District 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 Epping Forest District Council checks first — then submit a validation-complete pack.
Below is Epping Forest District Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Epping Forest is among the most restrictive authorities in the wider region, with roughly 92 per cent of the district in Green Belt holding its overall grant rate well below the national average while urban householder work fares better. 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 Epping, Loughton and Buckhurst Hill, 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 villas and terraces in the loughton and buckhurst hill commuter-railway suburbs, 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 Epping Forest Special Area of Conservation drives strict control on top of extensive conservation-area coverage. 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 Epping Forest. A few of the areas where they come up most often:
Two storey extension drawings for Epping — a historic market town with a High Street conservation area — dimensioned against the 3m and 7m limits and drawn to Epping Forest District Council's guidance.
Two storey extension drawings for Loughton — a Victorian and Edwardian forest-edge commuter suburb — dimensioned against the 3m and 7m limits and drawn to Epping Forest District Council's guidance.
Two storey extension drawings for Buckhurst Hill — St John's Victorian terraces and villas under Article 4 controls — dimensioned against the 3m and 7m limits and drawn to Epping Forest District Council's guidance.
Two storey extension drawings for Theydon Bois — a Green Belt village around a green on the Central line — dimensioned against the 3m and 7m limits and drawn to Epping Forest District Council's guidance.
Two storey extension drawings for Chipping Ongar — a historic market town with over a hundred listed structures — dimensioned against the 3m and 7m limits and drawn to Epping Forest District Council's guidance.
Two storey extension drawings for Waltham Abbey — a historic abbey town with a medieval core — dimensioned against the 3m and 7m limits and drawn to Epping Forest District 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 Epping Forest District 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 Epping Forest District Council validates and decides two-storey applications.
Send us your Epping Forest postcode and garden depth. We measure the 7-metre boundary rule against your plot, confirm designation status, and score your odds against live Epping Forest District 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 Epping Forest District 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 Epping Forest, the 7-metre rule is what most commonly forces a full application to Epping Forest District 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 Epping Forest gardens this is decisive, and we measure it on survey before any design work rather than discovering it at validation. Epping Forest District Council is the decision-maker.
Not under permitted development — two-storey side extensions always need a full application to Epping Forest District 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 Epping Forest address specifically. Epping Forest District 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 Epping Forest District 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 Epping Forest address specifically. Epping Forest District Council is the decision-maker.
