San Mateo Residential Architect
Contemporary Residential Project Experience in San Mateo County
As a San Mateo residential architect, Lori Hsu of LSH Architects designs contemporary homes, renovations, and additions that respond to both the character of each neighborhood and the way clients live today. San Mateo’s diverse housing stock—from mid-century modern and ranch homes to later suburban residences—offers rich opportunities for thoughtful transformation and modern living.

LSH Architects’ residential experience throughout San Mateo County includes work in Redwood City, Hillsborough, Atherton, Woodside, San Carlos, Menlo Park, Belmont, East Palo Alto, and La Honda. Projects range from custom new homes to complex renovations and additions, each shaped by clarity of layout, natural light, refined materials, and strong indoor–outdoor connections.
