The office, led by architect João Pedro Falcão de Campos, designed the three-bedroom vacation villa on a site close to Praia do Pego, one of the most popular beaches in the Comporta area, south of Lisbon.
Pura Comporta has a relaxed Mediterranean-style feel, with white walls, minimal detailing and light-filled interiors.
The zigzagging facade and roof divide the building up into three volumes, making it look like a trio of modest homes rather than a single property.
Inside, this dictates the layout. Bedrooms are located in half volumes at each end, while a series of living spaces occupy the central section of the floor plan.
There is also a mezzanine slotted above one of the bedrooms, which can serve as an extra sleeping space.
The building was raised off the sloping ground, creating space for parking underneath.
This provides an elevated terrace at the front, while the rear opens out to a large deck and swimming pool.
The owners commissioned Falcão de Campos for Pura Comporta after previously working with the studio on other projects, including their own home in Lisbon.
"We believe that we managed to develop a relationship of mutual confidence with them, which we consider very important for a positive outcome," João Pedro Falcão de Campos told Dezeen.
The brief called for a rental home in keeping with the local architectural vernacular.
This led the architect to incorporate traditional clay roof tiles and shading devices made from cane reeds.
"The choice of bright colours and the use of cane reed shading for the south facade, executed by local workers, were important construction decisions that relate to the typical houses in the area," he said.
Generous glazing frames views of nearby rice fields, while an internal courtyard creates an outdoor dining room on the most private part of the site.
The materials palette includes birch plywood and Estremoz marble, a Portuguese stone that forms the kitchen island.
"The challenges faced in this project are the same that we face in the majority of the projects developed in our office, which is to build well, making use of quality materials," said Falcão de Campos.
"Thankfully, the confidence we had with the client allowed us to build with quality and we are confident that the house is the demonstration of our belief."
