Looking for simplicity, he drew some inspiration from the Moravian mission churches of the 1800s in Mamre and Wupperthal, their white-lit interiors and absence of traditional papal paraphernalia evoking a sense of lightness and tranquillity. The same calm energy pervades the chapel at Bosjes.
The undulations of the cast-iron roof give the building its fluidity, complementing the curls of ''holbol" gables so typical of old Cape Dutch manor houses and in sync with the style of the original Bosjes farmhouse that was built in 1790 and still stands, beautifully restored.
The ripple effect also echoes the peaks and valleys of the nearby mountain ranges, and the raised tips on each side reaching up into the sky give the impression of wings in motion.
At dusk the chapel looks like it's floating, an illusion created in part by two strategically positioned reflection ponds out front, and by its slight elevation on a plinth that adds to the sense of weightlessness.
Steyn says that he wanted the 120-seater chapel to have a tactile quality to it. "I have strong childhood memories of running my hands along the powdery, uneven lime-washed walls of my grandfather's farmhouse."
The smooth exterior definitely elicits that response from many. Floor-to-ceiling windows allow for the shifting play of natural light and frame the dreamy views over the surrounding vineyards and gardens.
When designing the latter, Herman de Lange of CNdV Landscape Architects incorporated water features, pergolas, pathways and atmospheric lighting into an environment that encourages exploration and contemplation.
Each space is a subtle reference to Biblical elements or events, such as the huge water feature that's symbolic of the parting of the Red Sea and the winding walkway up the koppie (called Mount Sinai) that overlooks the entire property.
Inside the chapel the atmosphere is airy and the interior, designed by Liam Mooney, is unfussy, leaving no challenge to the scenic outlook.
Mooney also did the décor for the on-site Kombuis restaurant and Die Skuur, Bosjes' luxurious guest house.
Seeing the Bosjes Chapel is almost a religious experience in itself. It's a work of art that is an ode to divinity and a celebration of creation.
