Architectural Drawings in Wandsworth
Fixed-fee, MCIAT-chartered architectural drawings for Wandsworth homeowners — London Borough of Wandsworth validation and local constraints handled from the start.
Wandsworth is defined by its long Victorian and Edwardian terraced grids — the 'between the commons' streets — where the side-return and rear extension is the obvious route to more space. These are consistent house types repeated street after street, so the borough has clear views on rear depth, roof form and side-return design, and a technologist who knows the local pattern can draw to them from the start rather than discovering them through revisions.
Where you are in the borough shapes the route. Conservation areas such as Wandsworth Common, Tonsley, Nightingale Lane, Clapham Common and Battersea Park tighten control over rooflines, materials and side-return design, and the council applies Article 4 directions to basement development in parts of the borough, requiring a Basement Impact Assessment covering structural stability, drainage and groundwater. Near the riverside, Thames flood-zone considerations also come into play, while much of Battersea and the streets around the commons is Edwardian mansion blocks and converted flats where ownership, lease and party-wall context matters as much as the planning route.
We prepare Wandsworth planning drawings to the borough's residential extension and basement guidance, checking permitted development eligibility and any conservation-area or basement Article 4 constraint for your exact address before design begins, and drawing the engineer's structural calculations onto the set so these party-wall-sensitive terraces are handled cleanly. The fee is fixed and agreed up front — taken from our published price list — with free redraws until Wandsworth approves. We draw to the validation checklist and turn the drawings around in about seven days. The council's eight weeks begin the day after it receives a valid application, unless a longer period is agreed in writing.
Planning in Wandsworth: what to know before you apply
Wandsworth applies Article 4 directions to basement development in parts of the borough, requiring a basement impact assessment, and several conservation areas control roof and side-return design. Terraced side-returns recur across the borough, so we draw them to the council's residential extension guidance.

What the numbers say about Wandsworth planning decisions
These are London Borough of Wandsworth’s own reported figures, published by government rather than estimated by us. They are what we design against — a borough that refuses one householder application in five needs a different drawing package from one that refuses one in twenty.

Architectural Drawings for Wandsworth 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.
| Factor | Architectural Technologist | Architect |
|---|---|---|
| Council-accepted drawings | Yes | Yes |
| Typical fee | Fixed, published upfront | Varies by practice |
| Structural coordination | Named, insured engineer, coordinated by us | Often outsourced |
| Typical drawing turnaround | ~7 days | Several weeks |
| Best for | Extensions, lofts, conversions | Bespoke new-build design |
