Annexe and granny-flat drawings for Purleigh homes — designed to stay ancillary to the main house rather than become a separate dwelling, drawn to Maldon District Council's policies, delivered in days and revised free until your decision.
Maldon 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. Purleigh contains Purleigh, Purleigh (Addition1), Stow Maries World War One Aerodrome conservation areas (Purleigh designated 1975), 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.
Under Class B, a rear dormer stays permitted development up to 40m³ of added roof volume on a terrace or 50m³ on a semi-detached or detached house, while Class A allows a single-storey rear extension of 3m beyond the original rear wall on a terrace and 4m on a detached house before a full application is needed. In conservation areas such as Purleigh, Purleigh (Addition1) and Stow Maries World War One Aerodrome those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Purleigh is determined against an 8-week statutory target.
Purleigh (conservation area designated in 1975), Purleigh (Addition1) (designated conservation area), Stow Maries World War One Aerodrome (conservation area designated in 2008), Cold Norton (civil parish within Purleigh), North Fambridge (civil parish within Purleigh) and Stow Maries (civil parish within Purleigh) — these are the Purleigh pockets our drawings cover most. Heritage designations here include Purleigh, Purleigh (Addition1) and Stow Maries World War One Aerodrome. Maldon District Council weighs each proposal against Maldon District Council's development plan and the design policies it applies to householder applications, where the 1,530 homes here are 14% 1965-1972, 13% 1973-1982, 11% pre-1900, which is what sets the realistic roof and rear-projection options. On roofs the borough is shallow-pitched roofs and integral garages typical of that period's building and shallow trussed roofs typical of 1970s building, over late-1960s and early-1970s houses (14% of 1,530 homes), 1970s and early-1980s houses (13%) and Victorian and earlier houses (11%).
Purleigh's designated heritage is specific, and it is the first thing we check against your address: Purleigh (conservation area designated in 1975), Purleigh (Addition1) (designated conservation area) and Stow Maries World War One Aerodrome (conservation area designated in 2008). Inside those boundaries permitted development is curtailed and Maldon 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, Purleigh takes in Cold Norton, North Fambridge and Stow Maries. No Article 4 direction is recorded for Maldon District Council, but Purleigh's 3 conservation areas still limit permitted development on those streets.
On stock, Purleigh is late-1960s and early-1970s houses (14% of 1,530 homes), 1970s and early-1980s houses (13%) and Victorian and earlier houses (11%) — which is why shallow-pitched roofs and integral garages typical of that period's building and shallow trussed roofs typical of 1970s building govern what a loft or rear projection can realistically be. Maldon District Council decided 209 householder applications in the latest published year and granted 91%, with 56% issued inside the eight-week target. Those are the numbers our drawings are prepared against.
The full build-period split for Purleigh runs pre-1900 11% (170 homes), 1900-1918 3% (50 homes), 1919-1929 5% (70 homes), 1930-1939 5% (70 homes), 1945-1954 3% (50 homes), 1955-1964 10% (150 homes), 1965-1972 14% (220 homes), 1973-1982 13% (200 homes), 1983-1992 7% (110 homes), 1993-1999 7% (100 homes) and 2000-2008 7% (100 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.
Maldon District Council also decides for Heybridge East, Heybridge West, Maldon East, Maldon North, Southminster, Tillingham, Tollesbury and Tolleshunt D'Arcy, so a decision in Purleigh 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.

Councils do not decide annexes on square metres. They decide whether, once built, the accommodation forms part of one planning unit with the main house or a second one beside it. Maldon District Council looks at whether the garden is shared or divided, whether the annexe has its own street access and address, whether the occupier could live there entirely independently, and whether the two households would function as one. That is the whole case, and it is made or lost on the layout.
Purleigh is largely late-1960s and early-1970s houses (14% of 1,530 homes), 1970s and early-1980s houses (13%) and Victorian and earlier houses (11%), which shapes the realistic options: converting part of the existing house, extending it, or building a detached unit in the garden. A detached annexe can sometimes sit under Class E as an outbuilding incidental to the enjoyment of the dwellinghouse — but sleeping accommodation is generally not "incidental", so a garden annexe with a bedroom usually needs its own permission rather than relying on outbuilding rights.
In Purleigh's conservation areas — including Purleigh and Purleigh (Addition1) — a garden building is also judged on its effect on the character of the area, which limits height and footprint before the use question is reached. No Article 4 direction is recorded for Maldon District Council, but Purleigh's 3 conservation areas still limit permitted development on those streets.
An annexe almost always needs an application to Maldon District Council. Expect one where any of these apply:
We plan the annexe so its relationship to the main house is visible on the page — shared garden, connected access, a layout that reads as one household — and set out the case Maldon District Council has to test, rather than leaving the officer to assume the worst.
Below is Maldon District Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Maldon District Council granted 91% of its householder applications in the year to 31 March 2026, and Purleigh shapes what is approved here. Annexe applications are decided on use as much as design, so the supporting case matters as much as the elevations.

Across Purleigh, Purleigh (Addition1) and Stow Maries World War One Aerodrome, the annexes that succeed keep one shared garden, take access past the main house rather than from the street, and are modest against the host building — single storey where the plot is overlooked, and set back from boundaries. On late-1960s and early-1970s houses (14% of 1,530 homes), converting an integral garage or a rear ground floor is often approved more readily than a detached garden unit, because the ancillary relationship is self-evident.
Purleigh contains Purleigh, Purleigh (Addition1), Stow Maries World War One Aerodrome conservation areas (Purleigh designated 1975), so materials, fenestration and roof form are assessed against the appraisal. Where Maldon District Council grants permission, it commonly attaches a condition tying occupation of the annexe to the main dwelling. That condition is not a problem to be avoided — it is usually the mechanism that makes approval possible, and we draft the application on that basis rather than pretending the annexe is something it is not.
We draw annexes across Purleigh. A few of the areas where multigenerational schemes come up most often:

Three similar buildings, three different consents. This is what separates them.
| What you build | Planning status | Key test | What Maldon District Council checks |
|---|---|---|---|
| Garden room, no sleeping space | Often Class E permitted development | Incidental to the house | Height, footprint, boundary position |
| Annexe used by the household | Full application, usually with a tie condition | Ancillary use | Shared garden and access, layout |
| Self-contained unit, own access | New dwelling — full application | Separate planning unit | Policy on new homes, amenity, parking |
| Converted garage or ground floor | Often permitted, use still assessed | Whether use changes | Independence of the accommodation |
| Annexe on designated land | Full application | Designation | Character and appearance |
The ancillary/separate-dwelling distinction comes from section 55 of the Town and Country Planning Act 1990; outbuilding limits from the GPDO 2015, Schedule 2, Part 1, Class E.
A fixed process built around how Maldon District Council tests the use question as well as the design.
Tell us who the annexe is for and where it would sit on the plot. We confirm designation status and tell you honestly whether the scheme reads as ancillary or as a separate dwelling in Purleigh.
We measure the plot, the existing house and the access route, so the shared-garden and shared-access case can be drawn rather than asserted.
Chartered designers develop the annexe to your brief, with the layout, access and garden relationship arranged to support the ancillary case under Maldon District Council's policies.
We submit the application with a supporting statement on use, manage validation and case-officer queries, and revise free until Maldon District Council decides.
Almost always. Sleeping accommodation is generally not "incidental" to the enjoyment of a house, so it falls outside the outbuilding permitted-development right, and any annexe that could function independently raises a change-of-use question under section 55. In Purleigh we prepare a full application to Maldon District Council and make the ancillary case explicitly rather than hoping it is not asked.
A shared garden rather than a divided one, access through the main property rather than a separate street entrance, occupation by a member of the same household, and a physical and functional relationship with the main house. Maldon District Council weighs those together — no single feature decides it, but a separate front door and a fenced-off garden together usually settle it against you. This applies to your Purleigh address specifically.
Yes, subject to permission. A detached garden annexe is assessed on its scale against the plot, its effect on neighbours and the character of the area, and then on the use question. Keeping it single storey, set in from boundaries and served off the shared garden gives it the best prospect in Purleigh, particularly near designated areas such as Purleigh and Purleigh (Addition1). Maldon District Council is the decision-maker.
Commonly, yes — a condition tying occupation of the annexe to the main dwelling, so it cannot be sold or let separately. That is normally what makes approval possible, because it removes the concern that a new independent home is being created without going through housing policy. The condition runs with the land, so it matters at resale, and we explain the implications before you commit. This applies to your Purleigh address specifically. Maldon District Council is the decision-maker.
Yes. A new annexe is new habitable accommodation, so structure, fire escape, insulation and ventilation all apply, and a detached annexe close to a boundary raises fire-spread requirements as well. Planning and building control are separate consents with separate submissions — we prepare both so the approved design is the one that can actually be built. This applies to your Purleigh address specifically. Maldon District Council is the decision-maker.
A householder application runs to an eight-week statutory target; where the council treats the annexe as creating a new unit it becomes a minor application with a thirteen-week target instead. Which route applies depends on how the use is characterised, which is precisely why the ancillary case is worth making properly at the outset. This applies to your Purleigh address specifically. Maldon District Council is the decision-maker.
