Every draughtsperson starts with the same questions: what is there now, how big is it, and what are the drawings for. Answer them once in a request for extension plans in Cape Town, and we pass it to draughtspersons and architects who cover Cape Town and nearby areas of Western Cape.
Extension Plans in Cape Town
Many homes in Cape Town were built decades ago and are now being extended with extra bedrooms, enclosed patios and converted garages. Draughtspersons across Western Cape draw alterations and additions, check building lines and handle the council submission. Give the erf number and say whether the house has approved plans on record.
The main extension plans page explains the drawings, the standards and the costs in more detail.
Cape Town notes on drawings & surveys
Cape Town drawing jobs range from 3D renders for off-plan flats on Voortrekker Road and in Century City to as-built plans for older Woodstock cottages being sold. Restaurant owners in Kloof Street and on the Waterfront need kitchen and escape layouts. Landlords with student rooms around Rondebosch and Observatory often need measured plans for the municipality. Electrical plans should allow for load shedding backups and solar from the start.
Homes and buildings in Cape Town
Cape Town is a patchwork of stand types. On the Atlantic seaboard and in Constantia and Bishopscourt, large houses sit on steep slopes with views, wind and heritage rules. Woodstock, Observatory and the Bo-Kaap hold Victorian cottages where alterations are closely watched. On the Cape Flats, Mitchells Plain and Khayelitsha homes get backyard rooms and extra storeys, while the sandy ground and high winter water table shape the foundations. Northern suburbs such as Durbanville and Milnerton favour new estates with design guidelines. Plans go through the City of Cape Town, and many owners ask for both drawings and an engineer.

The requests we see from Cape Town usually come from:
- Families building a new house: an extra bedroom, a bigger kitchen or a study, drawn to join neatly onto the existing house
- Owners adding or changing rooms: alterations and additions plans that show demolitions, new walls and the roof join for council
- Developers and builders: extended unit types or an added storey on existing houses before they are resold
- Estate agents, sellers and landlords: plans that bring an altered house into line, so the sale can pass through transfer
- Rental and granny flat investors: a garage or outbuilding converted into a rentable room with its own entrance
- Shops, offices and restaurants: an added storeroom, kitchen or office wing on an existing shop or workshop
- Churches, schools and crèches: a classroom, hall or vestry added to an existing church or school building
- Farms, smallholdings and rural homesteads: extra rooms on a farmhouse or homestead, or an enclosed veranda for the family
Local tips for Cape Town
Most asked for in Cape Town: sloping-site homes, heritage alterations and backyard dwellings. Who draws them: studios in Woodstock, Claremont and the city bowl, draughtspersons in every suburb. A useful tip: ask whether an overlay zone or heritage area applies before the first sketch.
Extension Plans usually suits added rooms, storeys, garages and patios, drawn as existing and new work drawn together. For families building a new house, the biggest group here, that usually means an extra bedroom, a bigger kitchen or a study, drawn to join neatly onto the existing house. On the ground: south-easter wind, sandy Flats and steep slopes: ask for an engineer's report.
What to include in your request
- What you want to add and where it will go
- The address or erf number and the stand size
- Whether the house has approved plans on record
- Photos of the area to be extended
- Whether you will live in the house while building
A rough idea of the rooms is enough: the brief on this page turns it into a block plan and a floor area.
