Renovating Historic Buildings

Expert consulting services to architects, builders, developers, and community leaders who strive to preserve existing building fabric and cultural monuments. Work includes historic preservation, building restoration, modern additions and retrofits, and local, state, and federal tax credit acquisition.

Creating Homes for Aging in Place

Knowledgeable in the needs of aging home owners that seek independent living in their existing residences. Making smart and sensible retrofits can maximize the allowable budgets for construction, and allow homes to work efficiently for a high standard of living.

Accessible Residential Design

Preparing enhanced accessible design to work for your home and meet your needs. Whether it is removing barriers to entry, improving egress circulation, or creating functional bathrooms, kitchens, and living areas.

Together We Can Create Your Dream Home



Our process begins with a client interview to best understand your unique needs.



A thorough survey of the building and property is used to develop existing conditions documentation to begin the design work with solid information.



We develop initial schematic design work using client feedback along the way. The final design is honed over several iterations.



Technical drawings are developed of approved design and used to get pricing and construction permits.
