Property Description
Move-in ready professional building with 7 private offices across three levels, two kitchenettes, two restrooms, and flexible open space for reception, meetings, or training. Freshly renovated with recessed LED lighting, new paint, and wood-look vinyl plank flooring throughout, plus a corner lot with dual signage and on-site parking. Works for a growing practice or several teams under one roof. The lower level is a self-contained suite with its own exterior entrance and four private offices enclosed in frameless glass walls, giving you privacy and quiet while keeping the space open, bright, and connected. Every office has its own window for natural light, and a central corridor leads to a tiled kitchenette/break area with shaker-style cabinets, a stainless sink, and quartz-look counters, plus a dedicated restroom. On the main level, a spacious open room with a brick fireplace and a wall of windows makes a welcoming first impression and could serve as a reception area, conference room, or lounge. Beyond it, a second large room wrapped in bay windows fills with natural light and works well as a meeting space, open workspace, or additional offices. A second kitchenette on this level means no one has to go far for coffee. A short flight up, three private offices with doors and windows sit alongside a renovated restroom with tile floors, a modern vanity, and LED lighting. At the top, a large open space with dormer windows and built-in storage is ready for team meetings, training sessions, or a quiet place to spread out. Ideal for law, accounting, insurance, real estate, therapy, or any professional team that wants room to grow. Use the entire building or operate levels separately
