With a pool and upper deck, 535 Haynes Avenue belongs to a grand tradition of indoor-outdoor homes in Southern California. The property's rolling knoll offers ample space for barbecuing, play, and relaxation.

When Pablo Pérez Palacios’ Mexico City–based architecture firm PPAA was tasked with building an apartment tower to meet La Colonia Roma's need for additional housing, he faced a problem familiar to developers in historic neighborhoods everywhere. The site was occupied by a dilapidated home that dates to 1925, and local laws required that the facade and part of the structure be maintained. PPAA’s innovative approach was to cut the original three-story home in half, preserving enough of the building to front the street and hold two apartments replete with classic Victorian details like high ceilings and restored millwork. In the back of the lot, they designed a sleek eight-story apartment tower that would hold an additional nine apartments, for a total of 11 units. Not bad for a site that was previously an uninhabited single-family house.

Krisel, acclaimed for his tasteful, affordable home designs, infused this particular property with many of his signature features.
