UNUSUALLY for Hong Kong - and the south side of the island in particular - the 26-storey complex known as ''The Somerset'' is built from attractive rustic brick. Conveniently located between Repulse Bay and Deep Water Bay, the block comprises 37 duplex apartments, which include two penthouses and a combination of two and four-bedroom units, strata title. Each apartment has an unobstructed view of the ocean. The front door of one of the typical smaller 2,464 sq ft flats leads directly into the split-level combined living and dining area. Panoramic views of Repulse Bay can be seen through the floor-to-ceiling windows to the left of the dining area, which has a table with seating for eight people. To the left, close to the front door, is a downstairs cloakroom. To the right is the kitchen, compact but airy, and with an adjoining laundry and large maid's room. Four steps lead down to the huge rectangular sitting room which has splendid views. Straight ahead is an attractive balcony, ideal for barbecues, and beyond is a magnificent and unobstructed sea view of Middle Island and Lamma. Decor throughout downstairs is simple, with cream walls and wood block floors, solid timber doors and high-quality fittings. The apartments are being sold unfurnished, but are equipped with a reverse-cycle central air-conditioning system. The open wooden staircase leads to the master bedroom and en suite which features a jacuzzi. Gold-coloured taps contrast with the chocolate double basin, bidet and toilet. The upstairs level is a gallery design. While the bedroom windows look out to sea, those in the master bathroom are internal, overlooking the living room. The second bedroom is considerably smaller, but has plenty of fitted storage space, and its own bathroom. Outside, the facilities are equally impressive. On the first floor podium there is a large open-air swimming pool and a separate children's paddling pool, plus a playground and ample parking space.
