About Dagan Design & Construction
Dagan Design & Construction (DDC) is a design-build firm based in Encinitas, California, founded in 2012 by San Diego native Dagan Koffler. The company focuses on custom home design and construction, as well as luxury renovations, primarily serving the coastal communities of Southern California. Over the years, DDC has grown into a recognized builder and renovator in North County San Diego, while also expanding its building services across the broader Southern California region.
In addition to local projects, DDC offers interior design services nationwide, making their expertise accessible to clients beyond the immediate area. Their team includes project managers, interior designers, a landscape project coordinator, and office staff — all working together to deliver cohesive results from start to finish.
Services Offered
DDC operates as a full-service design-build firm, meaning they handle both the design and general contracting sides of a project under one roof. This integrated approach is intended to streamline communication and reduce the friction that can occur when design and construction teams are separate entities. Their core services include:
- Custom Home Design & Build — From concept through completion, DDC manages the full process for new custom homes and major renovations.
- Interior Design — Their in-house design studio provides space planning, interior elevations, furniture planning, mood boards, material and fixture selection, and vendor coordination. This service is available both for DDC's own build projects and as a standalone offering for clients working with outside builders.
- General Contracting — DDC provides general contracting services with an emphasis on organization, transparency, and realistic budgeting. They collaborate with outside architects, designers, and consultants when needed.
- Landscape Coordination — Through their landscape project coordinator, DDC also addresses outdoor spaces as part of a broader project scope.
- Commercial Interiors — In addition to residential work, DDC offers design services for commercial spaces, including space planning and material selection.
For post-construction needs, DDC points clients toward their sister company, DDC Next, which handles services such as home inspection, repairs, vehicle maintenance, yard maintenance, and pre-arrival preparation.
The Design-Build Process
DDC follows a structured process that moves through several defined phases. It begins with an initial walkthrough and consultation, where the team learns about the client's vision, how each space will be used, and whether architectural plans are already in place. If not, DDC can refer clients to architects they have previously worked with.
From there, the in-house design team develops a comprehensive design package. This typically includes:
- Space planning, interior elevations, and furniture planning
- Mood boards covering fixtures, finishes, and furniture selections
- Selection schedules and vendor coordination
- Sample gathering and material finalization
Once the design phase is complete, construction begins. DDC works with established relationships among suppliers, vendors, and subcontractors to execute the project. Because the same team handles both design and construction, communication between these two functions tends to be more direct, which can help keep timelines on track.
The process concludes with a final installation and walkthrough phase, during which furniture, décor, and finishes are placed and reviewed with the client. DDC also provides design documentation and care instructions for furnishings and finishes at project completion.
DDC serves clients locally in San Diego and the surrounding coastal communities, as well as remotely for interior design projects across the country. Their work spans residential renovations, custom home builds, and commercial interior projects.
