Coulsdon CR5, and Old Coulsdon in particular, pairs an historic village core around Bradmore Green with streets of interwar 1930s semis, where rear and side extensions and loft conversions are the common ways families extend.

The Bradmore Green Conservation Area removes several permitted development rights near the green, so even though Croydon has no Article 4 directions, we check whether a property falls inside that boundary before choosing permitted development over a full application.

Planning in Coulsdon (CR5): what to know before you apply

Coulsdon homes outside the conservation area often retain permitted development for rear extensions and lofts, while those inside Bradmore Green usually need full householder applications to Croydon. Croydon runs no Article 4 directions. We confirm the boundary and roof form before advising a route.

Typical Coulsdon housing stock

The heart of Old Coulsdon around Bradmore Green and Grange Park keeps an older village character, wrapped by the interwar and 1930s semi-detached houses that make up much of the wider CR5 stock, most with side and rear scope for extension.

Architectural Drawings for Coulsdon (CR5) homes: the package and the process

Every architectural drawings we prepare for an Coulsdon property is drawn to Croydon Council’s validation standards and tuned to the CR5 constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.

Architectural drawings are the overarching technical design for a building project — the master set from which planning drawings, building regulations drawings and construction details all flow. Where a planning application is one regulatory hurdle, the architectural drawing package is the complete design record of your home improvement.

DrawingsDirect provides that full service through MCIAT-chartered architectural technologists: the same professional, council-accepted output as an architecture practice, coordinated with structural engineering in-house, at a fixed fee.

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.

FAQ

Architectural Drawings in Coulsdon CR5 — 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 an extension in Croydon?+
It depends where in the borough you are. The interwar semis and detached homes of Purley, Sanderstead and Coulsdon often keep fuller permitted development rights than inner-London terraces, so larger rear and single-storey extensions can qualify. Conservation areas such as Addiscombe and South Norwood, and HMO Article 4 wards, restrict this. We check your address first and can confirm permitted development with a Lawful Development Certificate.
Can I build a larger extension on a Purley or Sanderstead plot?+
Often, yes. Croydon's generous suburban plots make substantial rear and double-storey extensions viable where a tight terrace could not accommodate them. The limit is usually design and amenity policy rather than space. We design to use the plot fully within permitted-development allowances or a well-evidenced full application, checking the limits for detached and semi-detached homes first.
What do Croydon's HMO Article 4 directions mean for me?+
In designated wards, an Article 4 direction removes permitted development for change of use to an HMO (C3 to C4), so a conversion to a house in multiple occupation needs a full application there. It doesn't affect a standard family extension, but if you are considering an HMO we confirm whether the direction covers your address and use before advising on a route.
How long does Croydon Council take to decide?+
Croydon determines most householder applications within the statutory eight-week period once validated. As a large borough spanning terraces to suburban plots, a complete, correctly scaled submission is the best way to avoid a validation query — we prepare Croydon drawings to the council's checklist to keep the application on track.
How much do planning drawings cost in Croydon?+
We quote a fixed fee upfront, typically around 30% below an architect's charge for the same council-accepted drawings, with free redraws until Croydon approves. Because plots here allow larger schemes, the fee tracks complexity — a single-storey rear differs from a double-storey — and we confirm it once we understand your plans.
