Design Consultant &
Home Representative
I design custom spaces and projects focusing on clarity, craft, and intent. From early sketches to final finishes - including contractor sourcing and project management - I design, source, and manage across residential, retail, and workplaces.
My Services
I partner with homeowners and collaborate with interior designers, architects, and contractors.
My broad set of capabilities allows me to step in as a homeowner’s representative or support designers by managing execution and building out custom projects like built-ins, small structures, or furniture.

Every project starts by understanding how your space needs to support your life - how you live, what you value, and the kind of atmosphere you want to create.
I design with purpose, working with you to shape projects that are functional, visually coherent, and aligned with your goals, timeline, and budget. Whether it's a kitchen renovation or an outdoor living room, the process is grounded in clarity and taste.

Design is just the beginning - I also take on the responsibility of making sure it gets done right. Acting as your representative, I help select contractors, gather and review bids, coordinate timelines, and manage communication to keep everything on track.
My role is to unburden you and protect your time, budget, and vision while keeping things moving forward.

-
I take on select built-ins, furniture, light construction, and smaller installations when it makes sense for the project.
With experience ranging from framing and cabinetry to retaining walls and landscape work, I’m able to take ownership of smaller scopes - or step in to support larger ones where detail matters most.

About | Justin Porcano
I’m a Marin County–based designer and project manager with two decades of experience spanning architecture, furniture design, construction, and hands-on building. I focus on thoughtful renovations - from designing and visualizing spaces to sourcing materials and managing contractors.
I also collaborate with interior designers, architects, and contractors to support their process and help bring their clients’ visions to life. Whether that means managing logistics, refining design intent, or stepping in where extra bandwidth is needed, I act as a reliable, detail-focused partner from start to finish.
As a homeowners’ representative, I also take on the responsibility of coordinating contractors, managing budgets and timelines, and ensuring the work reflects the design vision down to the last detail. I bring transparency, design intuition, and trusted oversight to every phase of the project - from concept to completion.
