Morden (SM4) sits at the southern edge of the London Borough of Merton, taking in the John Innes estate streets of southern Merton Park and the older village core around St Lawrence Church.

Architectural Drawings for Morden (SM4) homes: the package and the process

Every architectural drawings we prepare for an Morden property is drawn to London Borough of Merton’s validation standards and tuned to the SM4 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

FAQ

Architectural Drawings in Morden SM4 — 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 Merton?+

The interwar semis of Raynes Park and Morden often keep permitted development rights for rear extensions and lofts, so a full application isn't always needed. Conservation areas such as Wimbledon Village, Wimbledon Common and the John Innes estate at Merton Park restrict this. We check your street's designation first and can confirm permitted development with a Lawful Development Certificate.

What is special about building at the John Innes estate in Merton Park?+

The John Innes estate is a planned Arts-and-Crafts conservation area with a distinctive character the council protects closely — materials, proportions and rooflines are all controlled. Permitted development is often restricted there, so we design to the estate's character and prepare a full, context-led application, which is the reliable route to approval.

What do Merton's HMO Article 4 directions affect?+

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.

How long does Merton Council take to decide?+

Merton determines most householder applications within the statutory eight-week period once validated; Wimbledon and Merton Park conservation cases can involve additional consultation. We prepare submissions to the council's validation checklist to avoid the drawing queries that cause most delays.

How much do planning drawings cost in Merton?+

We agree a fixed fee before starting, typically around 30% below an architect's fee for the same council-accepted drawings, with free redraws until Merton approves. A suburban Raynes Park extension and a Wimbledon Village or Merton Park application differ in the evidence required, so we quote once we understand your address and project rather than by the hour.
