Passive Timber Frame House - Kirazlıyayla, Denizli

​Located in Kirazlıyayla, Denizli, Yücel House is designed as a passive house and planned as a 200 m² ecological structure. The building's load-bearing system is designed with a wooden frame and stone, and sheep wool is used as insulation material. Inspired by the harmony of stone and wood in regional architecture, the architectural design has been reinterpreted to suit Denizli's climate conditions; accordingly, wooden pergolas have been added and semi-open living spaces have been created. The cypress tree and ecosystem garden located at the entrance of the building offer a living space integrated with the natural landscape, while aiming to increase biodiversity. The grey water treatment area on the north facade is part of a system that collects and filters the building's grey water using reeds, and this water is planned to be reused for land irrigation. To provide natural ventilation for the building, an MHVR (Mechanical Ventilation and Heat Recovery System) has been integrated into the interior spaces. Thus, the building exhibits sustainable performance in terms of both energy efficiency and indoor air quality. Heating comfort is provided by an underfloor heating system, supporting the natural and balanced thermal comfort of the building. The timber frame system is designed as a double roof system on 20x5 cm timber uprights with 40 cm spacing. The lower rafters are 10x30 cm and form the lower roof with 60 cm spacing. The upper layer is a 5x25 cm lightweight timber frame, insulated with 25 cm of sheep wool between the rafters. In the main load-bearing walls and roof layer, breathable wood wool panels are used on top of the wool insulation to provide additional insulation and increase the rigidity of the timber frame. The workshop building is a 60 cm thick masonry stone structure with the same roof frame as the main building.
