Forty Hill (EN2) sits on a gravel plateau north of Enfield Town above the Turkey Brook and the Lea flood plain, a leafy semi-rural village centred on the Grade I listed Forty Hall and its estate.

The Forty Hill and Clay Hill conservation areas together protect a distinctive landscape of Georgian and Victorian cottages, paddocks and open space, where a 2009 Article 4 direction and Green Belt designation tightly control what can be built.

Planning in Forty Hill (EN2): what to know before you apply

EN2's Forty Hill and Clay Hill conservation areas, the Grade I Forty Hall, and surrounding Green Belt mean permitted development is largely displaced here; Enfield's 2009 Article 4 directions require applications for changes that elsewhere would be automatic. We check conservation, listing and Green Belt status before drawing so the scheme is pitched to what Enfield will accept.

Typical Forty Hill housing stock

Georgian and Victorian cottages and villas strung along Forty Hill and Baker Street around the Grade I listed Forty Hall of the 1620s, giving way to the largely rural, semi-open Clay Hill area of some sixty dwellings set among paddocks and public open space.

Architectural Drawings for Forty Hill (EN2) homes: the package and the process

The full architectural package has to serve three audiences that want different things from the same building. Planning officers want context, massing and materials; Building Control wants construction, insulation and fire strategy; your builder wants dimensions precise enough to price and set out from. One coordinated model behind all three keeps them agreeing with each other.

That coordination is the part clients notice later. When the planning set and the construction set are drawn from separate sources, the discrepancies surface on site — a beam that will not fit the approved roof line, a window head that has moved. We issue numbered, revision-controlled sheets so everyone is building from the same version.

Building form also sets how much design work there is to do. A detached house can usually take an addition on its own terms, while a terrace has to negotiate two party walls, a shared roof line and a neighbour's windows — the same brief, several times the coordination.

What do architectural drawings include?

A complete architectural package carries your project from idea to buildable detail, so builders quote accurately and councils and Building Control approve confidently.

  • Concept and feasibility sketches
  • Planning drawings for the local authority
  • Building regulations drawings with construction detail
  • Structural drawings and calculations
  • Schedules, specifications and material annotations

Architect or architectural technologist — which do I need in London?

For residential planning and building regulations work, an MCIAT-chartered technologist produces the same council-accepted drawings with the same professional accountability as an architect, typically at a lower fee. Councils do not score applications by the author's job title — they score the drawings. The table below compares the two on the factors homeowners actually care about.

What are the stages of an architectural drawing package?

A full architectural package moves through clear stages, each producing drawings you own and can act on. You can stop at any stage — many homeowners take a project to planning approval first, then commission the technical package once they are ready to build.

Concept and feasibility

Sketch options that test what your budget, plot and borough will allow, so you commit to a direction before detailed drawing begins.

Planning drawings

The scaled existing and proposed set your council assesses — floor plans, elevations, sections and site plans formatted to the borough's validation checklist.

Building regulations drawings

The construction-level package: sections, junction details, structural calculations and thermal and fire specification for Building Control.

Construction detail

The final layer of detail and schedules your builder prices and works from on site.

FAQ

Architectural Drawings in Forty Hill EN2 — FAQs

Are architectural drawings the same as planning drawings?+
Planning drawings are a subset of the architectural package — the drawings used specifically for a planning application. The architectural drawings also include building regulations and construction detail.
Will a technologist's drawings be accepted by my council?+
Yes. MCIAT-chartered technologists are a recognised professional body and their drawings are routinely accepted and approved by every London borough.
Can you take my project all the way to construction?+
Yes — from feasibility through planning, building regulations and structural detail, to a set your builder can price and build from.
Do I own the architectural drawings you produce?+
Yes. The drawings are yours to use, and any competent builder can price and build from them — you are never locked into a single contractor by the drawing package.
Can I commission just the planning stage for now?+
Yes. Many homeowners take a project to planning approval first and add the building regulations and construction package later. We stage the fee to match, so you only pay for the stage you need.
Do I need planning permission for a loft or extension in Enfield?+
Across Edmonton, Palmers Green and Enfield, the borough's interwar semis usually keep permitted development rights for rear extensions and hip-to-gable or dormer lofts, so a full application isn't always needed. Conservation areas such as Bush Hill Park and Winchmore Hill, and green-belt land to the north, remove or restrict those rights. We check your address first and confirm permitted development with a Lawful Development Certificate where it applies.
How does green-belt land affect my Enfield project?+
On green-belt properties toward the borough's northern edge, extensions are assessed against strict limits on disproportionate additions to the original dwelling. It does not rule out an extension, but scale and siting matter and the case must be evidenced carefully. We confirm whether your property is green belt and design a scheme that stays within policy.
What does Enfield's borough-wide HMO Article 4 direction affect?+
Enfield applies a borough-wide Article 4 direction removing permitted development rights for change of use to an HMO (C3 to C4), so a conversion to a house in multiple occupation needs a full application anywhere in the borough. It doesn't affect a standard family extension, but we confirm whether it applies to your intended use before advising.
How long does Enfield Council take to decide?+
Enfield determines most householder applications within the statutory eight-week period once validated; conservation and green-belt cases can involve additional consultation. We prepare Enfield submissions to the council's validation checklist to avoid the drawing queries that cause most delays.
How much do planning drawings cost in Enfield?+
We agree a fixed fee before starting, usually around 30% below an architect's fee for the same council-accepted drawings, with free redraws until Enfield approves. A suburban loft and a green-belt or conservation case differ in the evidence required, so we quote once we understand your address and project rather than by the hour.
