One Place to Belong. One Team to Trust.
A boutique San Diego real estate group specializing in off-market investments, design-led renovations, and elevated home sales.
The One Group operates at the intersection of real estate, design, and investment. Whether you’re deploying capital, selling a home, or navigating your next move, everything we do is guided by the same principle: thoughtful execution creates better outcomes.
Our work spans three distinct divisions, each built to support the others — and each held to the same level of care, discipline, and accountability.
Private Real Estate Investing, Done Properly.
The One Group Investment arm sources off-market San Diego properties, renovates them with intention, and brings them to market with precision. Our investors participate passively, while our in-house team manages every phase of the process — from acquisition to design, construction, marketing, and sale.
This model allows individuals to invest alongside experienced operators, without the burden of day-to-day decision making.
What investors value most is not just the outcome, but the experience:
clarity, transparency, and confidence in the process.


Selling Is a Strategy, Not a Listing.
Selling a home well requires more than exposure — it requires preparation, positioning, and restraint. The One Group approaches every sale as a curated campaign, designed to highlight what makes a property desirable and to create urgency in the right way.
From pre-market improvements and design guidance to strategic pricing and phased marketing, our process is built to achieve above-average results without unnecessary noise.
For homeowners, this means fewer surprises, clearer communication, and outcomes that justify the trust placed in us.
Work You Can See. Results You Can Feel.
Our projects reflect how we think — restrained design, purposeful upgrades, and respect for the neighborhoods we work in.
Each home tells a story of thoughtful improvement and careful execution, whether it’s a private investment flip or a client-facing sale.
Working Together As One
Seth Struiksma is the founder and lead advisor at The One Group. He works directly with investors and homeowners to navigate off-market opportunities, guide high-stakes decisions, and oversee every project from acquisition through execution.
Seth’s background spans acquisitions, renovation strategy, and residential sales across San Diego’s most character-rich neighborhoods. Clients value his clarity, responsiveness, and ability to balance creative vision with disciplined execution.
At The One Group, accountability isn’t distributed — it’s personal.

We live in the communities we work in. We invest in them, renovate within them, and care about how they evolve over time. Our neighborhoods are defined by character, walkability, and long-term desirability. Local insight into these areas isn’t a marketing claim. It’s the foundation of our work.
