We are tired hey? Every corner is a mall or shopping center? What about parks!?
10 Nov 2025
Another week, another retail centre - Waterfall's newest R600 million shopping centre has just thrown open its doors🍄 • Name: Mushroom Farm • Size: 27 000m2 • Retail stores: 50 • Taxi bays: 96 • Parking bays: 1150 • Architect: BAR architects • Construction started: September 2024 • Construction ended: October 2025 • Construction: Archstone Construction • Developer & centre owner: Century Property Developments • Location: corner of Allandale Road and President Drive, Kyalami, Midrand • Tenants include: Checkers Hyper (9000m2), Mr Price Home, Mambo’s, Dis-chem (1300m2), @Home, Bootlegger, Volpes, Mr Price, Baglios Porchinis, Whippet, Bargain Books, Sorbet, Pnp Clothing, Miladys, PEP Home, Seattle Coffee, Pet Science, BOA Beauty, Specsavers, Checkers Liquor, Wimpy, Crazy Store and DIal-A-Bed, PNA • Commercial offices and medical suites on the 1st floor Fun facts about the Shopping Centre’s construction: • 31 671 m2 of roofing sheets – enough to cover 13 private jet hangars • 44 805 m3 of concrete – enough to pave a road from Pretoria to Midrand • 3 900 m2 of tiles – sufficient to cover nine full-size basketball courts • 1 191 905 bricks – enough for over 130 RDP homes • 437 tons of steel – equal to 170 full-grown African elephants • 105 000 m3 of earth moved – more than one million wheelbarrow loads • 930 m2 of retaining walls – enough to wrap six double-decker buses vertically side by side The site used to be a working mushroom farm right next to the original Waterval Farm - hence the centre name. One of the tenants is Kiddies Aqua Swimming Academy - I can really appreciate a tenant like this in the mix. How cool (and convenient) to drop your daughter off for an extra swimming lesson and get your errands done at the same place. Parents spend hours in the car after school to and from extra murals - more tenants like this seem an essential in pulling that sort of foot traffic to your site. This will also be the home of Johannesburg’s first Mambos Storage and Home. Such a valuable tenant to have in a convenience centre. They are already planning phase 2 for the centre for 2026.

The parly portfolio committee chair, Tebogo Letsie, has seemingly already nailed his colours to the mast, supporting those who want to put Fort Hare under administration. Shameful. We must PROTECT principled people like Buhlungu against corrupt politicians news24.com/politics/appoint-…

Johannesburg has been ranked the world’s least walkable city, reflecting its high crime rate and heavy car dependency, which are symptoms of the city’s broader decline from years of mismanagement. dailyinvestor.com/south-afri…

I am more of a pessimist. I think Lagos (soon to be largest city on the planet) and other W African cities will look like Rio is 25 years because (1) they further become drug trafficking routes from Andes to Europe & (2) they’ll develop local retail drug markets (and armed gangs)
African cities need to build if they’re going to accommodate the ~900 million people moving in btw now and 2050. 🌆 But an African YIMBY mvt will have to go beyond just upzoning & reforming land use regulations. It must address underlying factor markets: land, capital, & labor

The best NBER summer institute session starts today: Urban Economics It's exciting to this take off as a policy and research area. Making cities work better — in rich and poor countries both — would solve so many of our problems. Starts at 830 ET, should be on NBER youtube.

Fine line to tread here, but there is no doubt the recent improvements in Metrorail service quality (under this CEO) has significantly improved the lives of thousands of commuters. Hoping this type of action by the Hawks doesnt compromise operations to keep the trains running.

My take on the Capitec CEO's pronouncement that the SA unemployment rate is actually 10%. Summary: "The Capitec CEO should stay in his lane and confine his pronouncements to topics such as borrowing and lending." businesslive.co.za/bd/opinio…

“There’s the biggest mall that’s coming to Johannesburg,” says Panyaza Lesufi with aplomb. “Twenty-four thousand square meters. That’s the BRICS investment we managed to get.” Yep! We continue to build palaces of consumption, and none of production.
