The versatility of treated SA pine as a structural material was once again demonstrated with its extensive use in the Tintswalo Atlantic Boutique Hotel in Hout Bay, Cape Town.
With unsurpassed views of The Sentinel, the hotel is situated on a pebbled private beach. It offers 10 luxury suites and a presidential suite, within metres of the waves. All the suites are linked to the main hotel by a boardwalk and the main building includes a restaurant overlooking Hout Bay.
The hotel is designed to blend with the natural backdrop, aesthetically and in the use of ‘organic’ structural materials. Most of the material used in the structure is SA Pine treated with Tanalith (CCA) timber preservative to H2 (interior above ground) and H3 (exterior above ground) hazard levels. The timber is treated to ensure an extensive lifespan, resistant to insect attack and withstanding exposure to the sea air and the Cape southeaster.
The timber was supplied by local timber treaters using Arch Wood timber preservative products. Three suppliers were involved in meeting the treated timber specifications for the project: Airton Timbers in Retreat, Timber Yard in the Noordhoek area, and The Pole Yard.
Contractor Keith Rudd says about 600 m3 of various types of treated timber were used, with most being Tanalith (CCA) treated timber and a small amount of Vascol (TBTN) treated and stained pine being used for exposed internal beams.
Exotic timbers such as European Oak, and Brazilian Cherry were used for the floor finishes.
Structurally the hotel is on timber pilings topped by the timber deck and floor, with the frame of the building and the roof all in treated pine.
Gerard Busse, marketing manager of Arch Wood Protection SA, says, “This prestige job underlines the attributes of treated timber: it’s renewable, environmentally friendly, strong and lightweight, flexible and, if correctly treated, offers a long life cycle.”
