Description
The Viking Square Professional Center is a newly remodeled, two-story, 20,600-square-foot professional building at 4343 Old Grand Avenue in the heart of Gurnee, Illinois. With suites ranging from 362 to 2,616 square feet, the building offers a rare combination of turnkey medical space and flexible professional office space in one of Lake County's most connected locations — with vacant units available for lease now.
For healthcare providers, Viking Square offers what is hardest to find in the market: fully built-out former dental and medical suites with plumbing and electrical already in place. Operatory-ready dental configurations, exam rooms, reception areas, and private offices allow physicians, dentists, therapists, and other practitioners to open their doors quickly and avoid the cost and downtime of a ground-up build-out. The building is already home to an established mix of dental, medical, and professional tenants, giving new practices a natural referral environment and steady daily foot traffic.
For professional and administrative users, the building offers bright, flexible office suites across a wide range of sizes — from a 362-square-foot private office to a 2,616-square-foot suite — well suited to insurance, legal, accounting, wellness, construction, and other service businesses.
Viking Square fronts Old Grand Avenue (approximately 9,100 vehicles per day) with visibility to Grand Avenue (Route 132), and is minutes from both the I-94 Tri-State Tollway interchange and Route 41. Advocate Condell Medical Center, Vista Medical Center, and Northwestern Lake Forest Hospital are all within a 10-minute drive. The building sits adjacent to Viking Park and Viking Middle School, about a mile from Warren Township High School's O'Plaine campus, and minutes from the region's major commercial engines — Gurnee Mills and Six Flags Great America. Metra service at Waukegan and Libertyville stations is roughly 13 minutes away, and O'Hare International Airport is about 40 minutes by car.
The property features abundant on-site parking at a ratio of 5.4 spaces per 1,000 square feet — 112 surface spaces, including reserved and covered options — a level of parking that comfortably supports patient-heavy medical uses. Elevator access serves both floors.

105
Suite 105 is a turnkey, 1,245-square-foot medical suite on the first floor, freshly remodeled and ready for immediate occupancy. Most recently home to a dental practice, the suite offers three former dental operatories that work equally well as exam or treatment rooms, a lab/kitchen, a private office, and a large reception and waiting area. The plumbing infrastructure that makes dental and medical build-outs so expensive is already in the walls: every room is plumbed, with lines professionally capped and ready to reconnect. The previous dental equipment has been removed, leaving a clean slate with new carpet, fresh paint, and updated interior finishes throughout. A dentist, physician, med spa, therapy practice, or lab can move in with minimal build-out cost — or use it as-is as professional office space.

100
Suite 100 is the flagship unit of Viking Square: a 2,616-square-foot medical suite on the first floor, home for many years to a large physician practice whose doctor has since retired. The suite is now available for a new tenant. The layout includes seven exam rooms, each with a sink, a large reception and waiting area, a private restroom, a kitchen area, and a separate staff entrance off the building corridor. The suite has been updated with new carpet, paint, and finishes, and the plumbing serving every exam room is in place.
Fully built-out medical space of this size is rarely available in the area — a practice can move in and begin seeing patients without the cost or delay of a ground-up build-out. Available for immediate occupancy.
