Steel doors and windows for an uninterrupted ocean view
Plus: Stand a chance to win a trip to the Rugby World Cup France 2023 with Jansen’s International Design Competition.

Doors and windows symbolise openness and provide a way in for people, light and air. They also protect from external elements such as water damage, corrosion and rust.
The Pure Sea Boutique Lodge, designed by architect Denis Maas of MaC Architects, is situated on an exclusive estate nestled in a private valley directly facing the ocean over Walker Bay. It opened its doors in November 2022.
It is designed so that the upper entrance level contains the foyer, wellness spa and the owners’ living and bedroom spaces. The four ultra-luxurious guest suites (along with library/kitchen facility and pool) are located underneath, being slipped forward towards the sea.
Steel is robust and resistant to mechanical and weather damage. It also offers several possibilities in terms thermal insulation and structural dimensioning, characterised by oversized openings and slimline face widths.
Two large double doors have been designed to provide a dramatic sense of arrival. The entrance doors are timber, while the second, which opens to the ocean, is a magnificent 3.8 x 3m tall double-hinged steel door that invite guests directly onto the beach.
As this iconic steel double door would not have been possible in aluminium, the owner of the lodge used the Swiss steel system known as Jansen Eco 60 specially coated to match the rest of the European fenestration. The dry corrosion protection is designed to withstand the extreme coastal elements, with a specification that includes a thermal zinc spray, primer, and UV-resistant textured finishing coat.
These systems are designed for double and triple glazing, depending on the requirements of each project. In this case, double glazing was specified to reduce heating and cooling costs while maintaining occupant comfort, aided by deep timber overhangs facing the beach.
As an innovative technology company and leading global supplier of steel profiles in the world, Jansen steel doors and windows system can keep corrosion at bay, thanks to finishes that protect against adverse weather. Indeed, what has proven its worth over many years in the automotive sector is now being used in the construction industry for the first time: galvannealed steel with a zinc-iron layer (ZF) for the basic corrosion protection of all steel profiles for window and door systems.
These profiles are also available in 316 stainless steel.
In their showroom in Cape Town, Jansen by M2G offers material properties that do not require further treatment, as well as a design configurator that allows you to vary the material and colour of doors or windows in the most extreme or temperate environments.
