Who I Work With

Homeowners

If you are planning a renovation, addition, or new build and are unsure where to start, I can help. I work with homeowners who value thoughtful design and want a steady guide through the process, from early decisions to final plans.

Developers

I partner with developers who want design, permitting, and coordination handled reliably. My role is to keep things moving and manage the details so you do not have to.

Services

  • Whether you’re starting with an existing structure or a vacant lot, I help turn your ideas into clear, buildable plans. We work together from early sketches through detailed drawings that are ready for permits and construction.

  • I stay involved during the permitting process so you don’t have to juggle comments from officials or handle administrative back-and-forth. My aim is to keep approvals moving without you feeling stuck.

  • Before design even begins, I look closely at your property and local regulations so we can spot potential hurdles early. If a variance or special permit is needed, I can help assemble the right documentation and walk it through with your team.

  • There are a lot of choices to make, and I’m here to help you make ones that match your vision and budget. I focus on options that will look great and hold up over time.

  • Sometimes a flat drawing isn’t enough. When it helps clients and builders see what’s coming, I provide 3D visuals so everyone is on the same page before construction starts.

  • For custom elements like built-in cabinetry, metal stair details, or other unique features, I prepare detailed shop drawings and work with trusted partners so pricing, fabrication, and installation go smoothly.

  • Our contractor recommended Olivia, and after meeting her and reviewing her work, we immediately connected with her sense of design and willingness to work with our aesthetic.

    Her understanding of construction and permitting complemented our contractors’, and together they handled unexpected issues with confidence. Beyond her expertise, Olivia’s calm, focused nature helped steady what can otherwise feel like a chaotic renovation.

    We’ve already hired her again for another major project.

  • The most valuable part of working with Olivia is her ability to combine creativity with practicality. She understands our vision but also considers functionality, timelines, and budgets, which makes the entire process smooth and efficient. Her attention to detail and clear communication have saved us time and elevated the overall quality of our projects.

    Olivia’s understanding of construction and permitting gives us a high level of confidence. She designs with real-world constraints in mind and ensures everything aligns with permitting requirements, helping us avoid delays and unnecessary costs. Working with her feels like having a true partner, not just a designer.

  • Olivia is collaborative, creative, and genuinely easy to work with. She communicates well, stays open to feedback, and approaches projects with a calm, practical mindset.

    She also understands construction, which shows up in her drawings and the way she handles issues on site. That combination of creativity and real-world awareness makes her a strong partner on any project.

My Approach

I’m Olivia, the founder of OS Design and Consulting. I run a one-person studio by choice so I can stay closely involved in every project and be accountable from start to finish.

I approach design with a practical, grounded mindset. Good design takes time and careful thought, especially when you’re building or renovating something meant to last. My role is to help guide the process, ask the right questions, and think through details that are easy to overlook but costly to fix later.

When we work together, you can expect a thoughtful, steady approach. I stay involved, communicate clearly with builders and municipalities, and focus on solutions that make sense for the site, the budget, and how the space will actually be used. I’m not interested in rushing decisions or reusing plans that don’t fit. I care about getting it right.

Clients often come to me because they want someone they can trust to handle the details, think ahead, and genuinely care about the outcome of the project.
