PROJECTS shelter and shade area, kitted out with modern cooking facilities including a braai and pizza oven. The summer kitchen roof is constructed entirely of custom-made loose rafters. “We had to pay special attention to the behaviour of the raw material during the construction process and use temporary bracing to prevent warping and bending of the wood due to exposure to the sometimes-harsh coastal environment,” shares Bosazza. Custom-made timber posts and laminated beams marry stainless steel brackets at roof height and create a clean and precise finish to this area. Main house roof The main house roof is a large and sprawling design. “Yet the resulting product has a deceivingly simple and concise look,” describes Bosazza. “Using the entrance and gallery as the central point the roof spans out almost symmetrically to the north and south ensconcing a wine cellar and guest suite to the north and dining, kitchen and master suite to the south. The roof is finished on the sea-facing side with low pitched verandas positioned under the lip of the main roof,” he says. According to Bosazza, the most breath-taking element of the roof and house is the double storey entrance which opens in to the spectacularly light gallery where exposed rafters and hanging chandeliers take your breath away. The construction of this involved lifting two large metal I-beams to double story height and setting them into place. “The beam profile is 305cm x 165cm, each beam is seven metres in length and weighed 287kg. Concrete plinths were in place to support the I-beams where they rested on the walls,” he adds. “The positioning of the loose rafters which were all custom-made laminated beams was an exact art – we worked closely with the engineers before the I-beams were manufactured to design and fit the rafter fixing plates in the correct positions. Once the I-beams were fitted the rafter beams, valley and jack rafters were all mitred on site. The I-beams were coated in marine epoxy before fitting and then boxed in with a timber framework and skimmed plasterboard before painting to finish.” The ceilings in exposed rafter areas – found in the entrance and gallery, verandas and summer kitchen – are created from tongue and groove ceiling board applied to the top of the rafters. “In these areas special attention was paid to ensure that the joints between the boards were not visible. We also undertook the painting of all these sections to ensure the final finish represented our attention to detail and fine workmanship.” A soft glow lighting effect was created with ceiling bulkheads located in the kitchen, dining and lounge areas as well as the wine and drinks rooms. “These bulkheads have light troughs to conceal the source of light which shines up onto the wall and ceiling,” says Bosazza.
