House NK is an existing one-storey house built in 1984 and is located in Larnaca, Cyprus. The design team was responsible for the complete renovation of the building envelope, internal spaces and upgrading its Energy Efficiency.

The initial design consisted of a separate living room, dining area, guest bathroom, kitchen area, 4 bedrooms and a private bathroom. The new design consists of a versatile open plan living and dining area, hidden guest bathroom and guest wardrobe, kitchen, and kitchenette with access to a bbq area, 1 office space, 2 bedrooms and a private bathroom. The redesign focused on maximizing the amount of natural light and natural ventilation in all spaces. To achieve that, one of the bedroom spaces was replaced with a new veranda space working almost as an inner courtyard. This allows for natural light and ventilation in the kitchen area, living room and the new office space. A new roof terrace was introduced with the addition of a steel structure unifying the volume of the ground floor with that of the staircase whilst allowing for a potential expansion of an additional floor following the growing family's needs.

One of the main ambitions of this project was to upgrade the existing construction which had an Energy Efficiency Category ‘F’ to a Category ‘A’. The energy upgrade was achieved by replacing all the aluminium windows, window doors, introducing new underfloor heating, new A/C units and placing Photovoltaic panels. The new design is a highly Energy Efficient house, with an Energy Performance Category ‘A’.
