PROJECT 49 sub-contractors under time pressure. “The same applies to all the shiny taps and fittings. Towards the end of the project everyone is under time pressure and the taps end up getting scratched, for which the plumber is liable. Our response to that is to protect these items by wrapping them in bubble wrap,” he explains. Changing the sequence of work is commonplace in every job, he says, yet these changes are seldom incorporated into future sequences – the same old sequence that was found not to work is automatically used again in the next project. “The most unique feature of the Serengeti plumbing system is that it is almost entirely invisible – pipes are not to be seen anywhere, only the tap, bath, basin and shower finishes are visible. It is also silent.” One of the challenges of the project was that by now most of the units in Phase 1 were occupied, and the considerable amount of construction still taking place had to be done during highly curtailed work hours of 08:00 to 17:00. “People opt to reside here because of its out-of-the- city quiet, charm and privacy, and that characteristic had to be maintained throughout construction.” This means there is a veritable traffic jam at 08:00 at the contractors’ entrance as everyone arrives for work. Many of them live conveniently in Tembisa, a 20-minute drive away even in peak hour traffic. Water and energy efficiency The project has energy- and water-efficient systems specified wherever possible. Du Toit says that Hansgrohe provided aerated shower roses which reduce the volume of water without affecting the experience of showering. “When showering, you’d think you’ve used five litres when you’ve only consumed two. Such ‘green’ taps are becoming standard in new projects. The problem remains free-standing baths which have to be filled for a satisfying experience. “Energy efficiency is obtained via the heat pumps and the tanks, and thereafter any efficiencies can only really come from how the hot water system is used. There’s been a big debate between solar systems and heat pumps, but which is preferable comes down to how hot water is being used. Where hot water is not often used – yet when you want hot water it must be immediately available – solar heating is good. Where hot water is used every day, a heat pump is useful in reducing electricity consumption. Both systems will have a back-up element which defaults to the mains electricity,” he says. Taps and other finishes had to be bubble wrapped to prevent damage by other sub-contractors in the rush to complete on time. There are three property styles: the larger three-bedroom units of 139m² face directly onto the Championship Whistling Thorn Golf Course; a second north-facing building offers two- and three-bedroom apartments measuring up to 120m²; while the third apartment type comprises of 12 luxury apartments laid out over two floors.

Bricks, cement, etc Builders Supply Precast slabs CCS Roof trusses HTNP Sheeting HTNP The Whistling Thorns development has been introduced to Serengeti Estates specifically to offer a broader range of housing options to the public in Kempton Park. It is located on the second fairway of the Serengeti's nine-hole golf course, and comprises of 188 luxury apartments, with architectural design by DHK Architects, laid out over three individual unit blocks. The buildings are spread out over a five hectare site, with plenty of green space between apartment blocks creating a mood of seclusion and enhancing the feel of tranquillity, which is the estate’s hallmark.
