LDA Architects is a professional corporation providing comprehensive services in planning, architecture and interior design. LDA is the continuation of a practice established in 1951, and today offers a full scope of design services from an experienced group of dedicated professionals. The firm is a minority-owned company registered with the San Francisco Human Rights Commission.

LDA Architects first concentrated its early work on single-family and multi-family housing throughout the San Francisco Bay Area. By the 1960's, the practice expanded to include banks, postal and educational facilities, HUD-funded housing complexes, low-rise and high-rise office buildings, and conversion of existing buildings to new uses. During the past decade, the practice has included civic works such as government offices, museums, parks, bridges, and meeting facilities.

Our clients have included speculative developers, corporations, city, county, state & federal agencies, and other architects. We have worked closely with general contractors in normal bid-build, negotiated bid, design-build, and value engineering arrangements. Past projects have included phased construction, alternate design bidding, fast-track construction, and other cost and time saving programs.

LDA provides cost and quality controls for every project that we serve. We approach cost control and value engineering as conscious parts of the design effort. We believe that every project should enjoy the benefits of efficient and economical design and engineering for all building systems.

LDA works closely with construction professionals to create an accurate budget that is monitored during the entire course of a project. To effectively prevent after-the-fact cost cutting, we recommend constant cost review from the earliest stages of design. Cost information is a design tool that should be used in parallel with other design devices. We have had considerable experience in design-build construction contracts, design-assist construction, and negotiated bid projects that have been successfully completed under this philosophy, for the entirety of our long history.


The control and balance of quality is an integral part of managing the cost of any project. It is convenient to downgrade the quality of any product or assembly that may be used on a project, but the project will be forever adjudged "cheap" by that one glaring weak element. LDA considers the balance of quality to be more important. The deliberate calibration of the entirety of a project to meet a uniform level of quality is essential. As the budget is established early, so too is the level of quality. This is another benefit of early and constant cost monitoring.




LDA has many years of experience working with the construction industry on design-build projects. We understand the building process and can help clients and builders make better budget and schedule decisions. Successful collaboration with contractors results in long lasting client relationships, better cost control, and more profitable projects for all parties.

LDA specializes in design-build projects from $5 million to $30 million. As part of the design-build team, we frequently attend the first meeting between the builder and prospective client and often help the builder secure a contract with the client.

We bring the following benefits to the process:

  • Help client develop vision for the project
  • Assist client/builder define scope of work
  • Explain regulatory requirements
  • Explain project process to client

LDA Architects has a long history of projects designed in cooperation with the construction industry. Starting with our earliest projects, we have combined the qualities of architecture with the knowledge and sensibilities of construction professionals. The result has been award-winning projects that have created long lasting client-builder-architect relationships.

Our arrangements have been as varied as the projects for which they were used, but the results have always been successful and profitable for all parties.
