This ambitious dual-lot split development in Concord features a two-story primary residence and an Accessory Dwelling Unit (ADU) built over a garage on each lot. Bertolami Engineering was brought in to manage the project comprehensively, guiding it from initial conceptual design through final construction support. By utilizing Structural Insulated Panels (SIPs) for both the main houses and the ADUs, we ensured a highly efficient, sustainable, and rapid build. The first lot's construction is nearing completion, showcasing the precision of our permit packages and structural planning, with the second lot slated to break ground this summer of 2026.
Whether you are planning a new SIPs build, a residential addition, or need comprehensive permit drawings, our team is here to help. Share a few details about your upcoming project below, and we will reach out to schedule a consultation.
