in the ‘roofscape house’, QASTIC has one fundamental design question about hillside residential architecture which dictates the formation of the space. how to take advantage of the slope as an opportunity to redefine the role of a courtyard? as a result, inspired by the geography of the hillside lot in orange county, a continuous and accessible roofscape took shape to embrace all elements of a yard in a california house.
exterior view during night time
californian based QASTIC lab‘s design program responds to a typical house for a family of four people. the oldest son is interested and educated in astronomy. therefore, he may want to keep some of his telescopes in the house to take advantage of the clear sky to study the stars, galaxy and our universe above.

looking through the site capacities and the precise language of the program, QASTIC has narrated a story which has a beginning and an end. this story begins with an outside roofscape which is the entry pad that directs us to the interior or the roofscape. the roof path initiates with the BBQ area which leads to the fire pit, jacuzzi and eventually the observatory platform at the top of the path. as a result of the connection between the lower and upper part of the property, the house itself has taken its shape in four elevating levels while letting every space have direct access to the roof.

responding to limitations of grading in cut and fills in the site; four separate pads are connected in smooth transitions by stairs. at the same time, it creates the optimal opportunity for interior seating, indoor cinema and library applications. while the interior public areas of this linear house happen in the middle of the structure, the master bedroom and rooms are located at both ends of the house again offering direct access to the landscaped roof.
view towards the second floor
the top end of the path ends or begins with an observatory spherical shape exterior pavilion which provides direct access to the galaxy observation telescope. this orchestrates a unique concept which may offer a multifunctional and exceptional experience of the space. the top pavilion space precisely frames the sky to allow the journey of traveling on the roof to finish with a poetic transition to the sky above.
