What gets put up around Benoni

Lakes and smallholdings set Benoni apart from the rest of the East Rand. Owners on plots in Putfontein, Benoni AH and Rynfield AH put up staff rooms, timber cottages and stables, and lakeside homes in Lakefield and Farrarmere ask for pool houses, garden offices and granny flats. Daveyton and Etwatwa have a large market for nutec rental rooms and second units on township stands. Crystal Park and Northmead mix both. Board yards and erectors work out of the industrial areas near the N12 and in Apex, and many also cover Brakpan. Summer storms on this part of the Highveld carry heavy hail and lightning, and frost gathers by the lakes on still winter mornings.

Frequently asked questions

How much are granny flats in Benoni?
In Benoni the delivery and the ground often move the price as much as the building does. Nobody publishes a reliable range for this, which is why written quotes for the same job matter. Send your request and a builder serving Benoni will quote you.
What lead time should I expect in Benoni?
For granny flats: often erected in days once plans are approved. Locally: wendy houses usually in 1 to 3 weeks; cottages and granny flats quoted per job. Council approval comes before the build, so start that early.
What should I know about building in Benoni?
For granny flats, start with how it gets to you: flatbeds via the N12 and R21; plot roads in Putfontein can be soft after rain. Then the weather: heavy summer hail and lightning, frosty lakeside winter mornings. And ask this: ask whether the price includes delivery on the plot road and setting out. If the ground needs work first, see slabs in Benoni; for council plans, plans in Benoni.
Do I need plans for granny flats in Benoni?
Anything lived in, and most buildings bigger than a small shed, needs plans approved by the Benoni council under SANS 10400 before it goes up. Approved plans needed: it is a dwelling. Ask each supplier what paperwork they supply with the building.
Do you build or deliver the homes yourselves?
No. We don't make, sell, deliver or erect anything. We pass your request to independent suppliers and builders, who quote you directly. Give the size and the stand, so the quotes are easy to compare.
