Dormer loft conversion plans in Four Marks & Medstead

Four Marks & Medstead planning decisions and design rules

East Hampshire District Council granted 91% of the householder planning decisions it made in its latest published year — 4 points above the 87% England-wide householder average. Four Marks & Medstead contains the Chawton conservation area (Chawton designated 1977), 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.

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. Four Marks & Medstead carries at least one Article 4 direction, and conservation areas including Chawton remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Four Marks & Medstead is determined against an 8-week statutory target.

Chawton (conservation area designated in 1977), Four Marks (civil parish within Four Marks & Medstead), Chawton (civil parish within Four Marks & Medstead) and Medstead (civil parish within Four Marks & Medstead) — these are the Four Marks & Medstead pockets our drawings cover most. Heritage designations here include Chawton. East Hampshire District Council weighs each proposal against East Hampshire District Council's adopted local plan and its householder design guidance, where the 3,150 homes here are 13% 1955-1964, 12% 2000-2008, 9% 1983-1992, which is what sets the realistic roof and rear-projection options. On roofs the borough is shallow gabled roofs typical of that period's building and trussed-rafter roofs typical of 2000s building, over late-1950s and early-1960s houses (13% of 3,150 homes), 2000s houses and apartments (12%) and 1980s estate houses (9%).

Why a Four Marks & Medstead scheme is judged on Four Marks & Medstead terms

What is permitted in Four Marks & Medstead turns on designation first, so that is where we start: Chawton (conservation area designated in 1977). Inside those boundaries permitted development is curtailed and East Hampshire District 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, Four Marks & Medstead takes in Four Marks, Chawton and Medstead. East Hampshire District Council has 50 recorded Article 4 directions — check the address before assuming PD applies in Four Marks & Medstead.

On stock, Four Marks & Medstead is late-1950s and early-1960s houses (13% of 3,150 homes), 2000s houses and apartments (12%) and 1980s estate houses (9%) — which is why shallow gabled roofs typical of that period's building and trussed-rafter roofs typical of 2000s building govern what a loft or rear projection can realistically be. East Hampshire District Council decided 327 householder applications in the latest published year and granted 91%, with 24% issued inside the eight-week target. We draw to that record rather than to a national average.

The full build-period split for Four Marks & Medstead runs pre-1900 3% (90 homes), 1900-1918 2% (70 homes), 1919-1929 2% (70 homes), 1930-1939 5% (170 homes), 1945-1954 4% (120 homes), 1955-1964 13% (400 homes), 1965-1972 9% (270 homes), 1973-1982 7% (210 homes), 1983-1992 9% (290 homes), 1993-1999 5% (170 homes) and 2000-2008 12% (370 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.

East Hampshire District Council also decides for Alton Holybourne, Alton Whitedown, Bentworth & Froyle, Bramshott & Liphook, Buriton & East Meon, Headley, Horndean Catherington and Liss, so a decision in Four Marks & Medstead 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 Ajax House/Plowden House, Liphook, Bedford Road, Petersfield, Bellhanger Enterprises, Bentworth and Bentley Business Park, Bentley. 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.

The rear dormer, drawn for Four Marks & Medstead roofs

The box dormer is the workhorse loft, and most of Four Marks & Medstead is built for it — the borough runs to late-1950s and early-1960s houses (13% of 3,150 homes), 2000s houses and apartments (12%) and 1980s estate houses (9%) under shallow gabled roofs typical of that period's building and trussed-rafter roofs typical of 2000s building, and a flat-roofed box across the rear slope is the cheapest cubic metre of full-height space those roofs give up. East Hampshire District Council tests the dormer against East Hampshire District Council's adopted local plan and its householder design guidance, and because permitted development turns on a number, the volume you propose against the volume you have left is the first thing an officer or a certificate checks.

That is why the arithmetic goes on the drawings. We calculate the box against the 40- or 50-cubic-metre allowance, count any earlier roof enlargement into the total, hold the flat roof below the ridge and set the face back off the eaves so the dormer reads as subordinate. Four Marks & Medstead contains the Chawton conservation area (Chawton designated 1977), so materials, fenestration and roof form are assessed against the appraisal, so the cheeks, the window line and the material are drawn to answer it rather than invite a query.

Where Four Marks & Medstead's streets are protected — Chawton among them — the Class B dormer right is switched off and even a modest rear box needs consent. East Hampshire District Council has 50 recorded Article 4 directions — check the address before assuming PD applies in Four Marks & Medstead. We confirm the designation before the box is sized.
