Catford (SE6) in Lewisham is defined by its consistent Edwardian estates — above all the Culverley Green conservation area and the neighbouring Corbett Estate, whose uniform terraces give the area a strong, coherent character. That consistency is exactly what the planning controls here are designed to protect.

The Culverley Green conservation area carries an Article 4 direction controlling householder alterations, and the wider Corbett Estate streets are assessed for their uniform Edwardian frontages, so dormers, extensions and elevation changes need to respect the established pattern. Lewisham's small-HMO Article 4 direction adds a control on conversions. We design Catford schemes to fit that grain.

Planning in Catford (SE6): what to know before you apply

SE6's Culverley Green conservation area carries an Article 4 direction that controls householder alterations within the Edwardian estate, and the surrounding Corbett Estate is valued for its uniform frontages — so extension and loft designs in Catford are judged closely against the established Edwardian pattern. Lewisham's borough small-HMO Article 4 direction is a further control on conversions.

Architectural Drawings for Catford (SE6) 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 Catford SE6 — 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 side-return extension in Lewisham?+
On the Victorian and Edwardian terraces of Brockley, Forest Hill and Hither Green a single-storey side-return or rear extension can fall within permitted development, so a full application isn't always needed. Conservation areas such as Blackheath, Brockley and Telegraph Hill restrict this. We check your street's designation first and can confirm permitted development with a Lawful Development Certificate where it qualifies.
What does Lewisham's borough-wide HMO Article 4 direction affect?+
Lewisham 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 or loft, but we confirm whether it applies to your intended use before advising on a route.
Can I convert the loft on my Lewisham terrace?+
Usually, yes. The terraces of Brockley, Forest Hill and Hither Green suit hip-to-gable and dormer loft conversions, which frequently qualify as permitted development within the volume limits. Outside the conservation areas this is often the quickest route. We confirm eligibility against those limits and any designation, then produce the planning and building-regulations drawings.
How long does Lewisham Council take to decide?+
Lewisham determines most householder applications within the statutory eight-week period once validated; conservation cases can attract additional consultation. The dense terraced streets are party-wall-sensitive, so the commonest delay is a drawing query — we prepare submissions to the council's validation checklist to keep them moving.
How much do planning drawings cost in Lewisham?+
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 Lewisham approves. A side-return, a loft and a conservation-area scheme differ in complexity, so we quote once we understand your street and project rather than charging by the hour.
