Structures smaller than 120 m 2 Gold award: Logo Homes for House Riley

Alterations & Additions Gold award: THK Construction for House Hansen

House Riley, a bachelor cottage, is the third timber dwelling to be built on a large erf high up in Hout Bay. It was built as domestic and guest accommodation with a high quality of design and finish within a strict budget. Built on an area entirely covered in large rocks on a steep plot, the build necessitated tricky excavations and substantial rock break- ing, the product of which was retained on site for later use.The deck cantilevers out from the house, because there was no suitable ground underneath to support a standard pole construction. The house comes fitted with a gas geyser for all the water heating, a gas hob for cooking, and lighting with low-power fittings.

Bronze award: Timbercraft for House Bruckner German precision and a handful of naysayers were no match for timber frame building when it came to the addition to House Bruckner. The plan consisted only of a ground floor and first floor plan and four side elevations; no detailed drawings, no electrical drawings and no drainage drawings were supplied, and the roof had to be redesigned. Needless to say, the builders kept good company on site with architects, engineers and interior designers. The ground floor had to be ready in six weeks for the client to move in, so he could sell his current dwelling. The end result, which was completed within estimated time, was to the satisfaction of the client, his wife, his doubting construction expert friends, the new architects and engineers, and the council. Architect Thomas-Gey Engineer Anthony Cave, Cave Consulting Engineers Silver award: Logo Homes for House Randles The brief for the alteration to House Randles, which butts up to the sand dunes that stretch to the beach in Noordhoek, was to link the main house with the cottage, which is predominantly used as an office, and to have internal access to the garage off the basement, and create a new entrance hall with guest walk-in closet, new kitchen, domestic bathroom, laundry and storeroom. The final product delivers to the clients’ exceptionally high standard of finish with exposed cupola in the entrance hall, welcoming in natural light, and two floor windows to diffuse this light downwards through to the basement rooms. Architect Jacques Cronje Timber Design Engineer Deon Botes, Poise Consulting Engineers Situated in Glencairn on a steep hillside overlooking False Bay and Simonstown, House Hansen’s location made this a very challenging project, which required that all the material had to be carried to site by hand. The brief was to add one bedroom and a jacuzzi room downstairs, a new deck area and staircase to the house. As the project developed, the client added a number of ex- tra updates, including changing all windows and doors to alumin- ium, recladding the whole house, adding a new store room under the house, and redoing roof shingles and waterproofing, etc. Architect Sadie Jones Engineer Meny-Gilbert & Associates

Silver award: THK Construction for House Bruce A retired engineer and yacht builder commissioned the contractor to build him the workshop of his dreams, which was built in his Constantia garden. The client designed the 32 m 2 workshop alongside the designer, to have exterior timber cladding, OSB board internal cladding, exposed rafters and a Heraklith acoustic ceiling. House Bruce, a dream made real, was delivered in just over two months. Draughtsman Greg Selfe, Draftcon Building Plans

Structures larger than 120 m 2 Gold award: Henton Homes for House Verster

Built in Lakeside against the mountain side on a property with a 60 degree slope, this is a ‘hybrid’ house consisting of 90% timber frame with the use of a steel portal frame as the main structural element. This allowed for building on a very steep site without excessive foundation costs, as most of the building is suspended. A large rammed earth wall provides mass and is an architectural feature. Only the bathroom is on a conventional brickwork and concrete surface bed; the garage is on a suspended rib-and-block slab. An excellent example of a ‘hybrid’ house made up of materials that are best used for their purpose. Architect Jacques Cronje Timber Design Engineer Deon Botes, Poise Consulting Engineers
