montalba architects embeds LR2 residence on a hillside in pasadena

santa monica-based architecture practice montalba architects has completed the LR2 residence in pasadena, california, a house overlooking the city and its adjacent mountains from its hillside perch. the 4,200 square-foot house follows the matchbox concept, where the layered volumes of the structure are integrated into the downhill slope of the lot, creating open spaces between the structures for integrated planting areas, covered terraces, and dial linear water features for passive cooling.

at montalba architect’s LR2 residence, the entry space flows with the landscape, guiding visitors along a reaching sidewalk that extended under the mass of the building. the compression of the resulting space offers a unique arrival experience incorporating the natural creek just beyond the front door, which is nestled on the second floor. outdoor breezeways, porches, courtyards, covered walkways, and an immense rooftop deck extend the reaches of the limited floor area to the outdoors and provide immense views.

inside, the house includes guest suites, a home office, gym, and a theater screening room, as well as abundant outdoor spaces, all showcasing views of the surrounding hills and valleys. following the existing creek, the front stairs create an arching path to a bridged entry portal, all the while showcasing panoramic views of the house. as the front door opens, the dark, angular façade of paneled concrete gives way to a light-filled interior of softwood and bright white finishes.
