Extension Plans in Johannesburg
Many homes in Johannesburg were built decades ago and are now being extended with extra bedrooms, enclosed patios and converted garages. Draughtspersons across Gauteng 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.
Drawings & surveys in Johannesburg: local notes
Many sellers in Craighall, Greenside and Bryanston West discover at transfer that a lapa, an enclosed stoep or an extra bedroom was never approved, and as-built drawings are then needed. Landlords in Braamfontein and Doornfontein want commercial layouts for shops, student flats and restaurants, while Rosebank agents order floor plans for listings. Electrical layouts matter for solar and backup power in older houses with tired wiring.
Homes and buildings in Johannesburg
Johannesburg is a patchwork of building types, and the plans differ with each one. In Parkview, Emmarentia, Melville and Linden, old stands of 1,000 square metres and more are being subdivided or filled with garden cottages, while Braamfontein, Maboneng and Jeppestown have offices and warehouses turned into flats. Soweto's Dobsonville, Meadowlands and Orlando West see families extending RDP and four-room houses, with backyard rooms for tenants. The ridges of the Witwatersrand give sloping stands, and mining ground in the south needs care. Plans are drawn by local draughtspersons, architectural technologists and architects, who quote you directly once your request reaches them.

Typical extension plans requests in the area 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
- Rental and granny flat investors: a garage or outbuilding converted into a rentable room with its own entrance
- 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
- 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
Local tips for Johannesburg
Popular here: subdivision cottages, backyard rooms in Soweto and inner-city flat conversions. Ask each draughtsperson about this: ask for the stand's zoning and any title deed conditions before the first sketch. Who does the work: draughtspersons in most suburbs, architects in Parkhurst, Melville and the city centre.
Around Johannesburg the largest group asking is families building a new house, which usually means an extra bedroom, a bigger kitchen or a study, drawn to join neatly onto the existing house. Expect sACAP-registered, drawn to SANS 10400 as the baseline, and keep in mind: ridges and mine ground in the south: ask about a soil report and engineer's footings.
