The repositioning — committed

$5 million, and a completion date.

Construction begins September 2026 and completes in 2027 — the atrium rebuilt, a new entry and drive court, and suites delivered finished. Sign a lease now and your practice opens its doors into a completed building.

  1. Atrium & common areas

    The four-story atrium rebuilt — new feature wall, lighting, flooring, and seating, plus corridors, restrooms, and elevator cabs.

  2. Exterior & site

    A new entry canopy and drive court, refreshed facade, landscaping, and parking.

  3. Move-in-ready spec suites

    Turnkey medical suites delivered finished, so a practice opens without waiting on a build-out.

22,874 square feet, in 12 pieces.

Every available suite in the building, drawn to scale against its floor plate. Filter by size, by floor, or by whether a space can be taken with its neighbour — the plan and the list move together.

Spec Suite 203 — floor 2, 1,383 RSF

Move in without a build-out wait.

Suite 203 is already drawn, specified and permitted: 1,383 rentable square feet on the second floor, laid out as three exam rooms, a lab, a private office and a waiting room. Every material is selected. It is delivered finished with the rest of the building in 2027, so a practice signs a lease and opens — with no build-out to design, price and wait out.

Room program of Spec Suite 203 — ten rooms in 1,383 rentable square feet A schematic of the ten rooms in Suite 203, drawn with north at the top. Along the south side of the suite are the waiting room and, beside it, the reception desk, with a coat closet between them and the clinical rooms. A single corridor runs north from reception through the middle of the suite. Three exam rooms open off that corridor — two on the east side and one on the west — together with a lab and a washroom on the west side and a private office at the north end. The suite entrance is on the east side of reception. Rooms are drawn as plain rectangles at approximate relative size and position; this is a diagram of the room program, not the architectural drawing, and nothing on it should be measured.RM 208Exam RoomRM 209WashroomRM 210LabRM 205CorridorRM 207Private OfficeRM 206Exam RoomRM 204Exam RoomRM 201WaitingRM 203Coat ClosetRM 202ReceptionNSUITE ENTRY

A schematic of the room program, not the architect's drawing and not to scale. Rooms are shown as plain rectangles at approximate relative size, and adjacency is approximate — the arrangement is the one in the permit set, the geometry is not. Room numbers are the architect's and are prefixed RM here, because the suite is Suite 203 and the coat closet inside it is also numbered 203.

The chips are on-screen approximations. Every material here is a physical, mostly textured product — carpet tile, luxury vinyl, laminate, solid surface — and no screen colour is a match for one. Read the manufacturer, style and colour code as the specification, and the chip only as a rough indication of tone; specify from the manufacturer's own sample.

Location — Bloomingdale, DuPage County

2 miles from a hospital, and on the I-355 interchange.

303 East Army Trail Road sits on the north side of the road it is named for, with the pond behind it and the I-355 four-way interchange at Army Trail Road to the east. UChicago Medicine AdventHealth GlenOaks is 2 miles to the south and Ascension Alexian Brothers is under 7 miles to the north-east — a practice here stays inside the referral network it already works in.

Schematic map of Willowlake, 303 East Army Trail Road, Bloomingdale, IL A hand-drawn schematic, not to scale and not a survey. Army Trail Road runs east to west across the drawing as the main axis. Willowlake sits on the north side of it, set back behind its pond. To the east, the Interstate 355 tollway crosses Army Trail Road at a four-way interchange. Two rings are drawn around the building at 2 and 7 miles. UChicago Medicine AdventHealth GlenOaks is pinned 2 miles to the south, on the inner ring, and Ascension Alexian Brothers is pinned to the north-east at under 7 miles, just inside the outer ring. The ring radii and the two hospital pins are drawn in proportion to those distances.PONDWILLOWLAKEARMY TRAIL ROADI-355FOUR-WAY INTERCHANGEAT ARMY TRAIL ROAD2 MILES7 MILESUCHICAGO MEDICINEADVENTHEALTH GLENOAKS2 MILESASCENSIONALEXIAN BROTHERSUNDER 7 MILESN

The building — 1996, Class B

67,000 square feet, on 4 floors.

A 67,000 SF Class B building on 4 floors, with a 17,074 SF typical plate and 79 surface spaces at the door — a 4:1,000 SF ratio, which is what a practice running back-to-back appointments actually needs. The $5 million repositioning begins September 2026; the frame, the plate and the parking below are what it is being spent on.

Questions, answered

The first call, in writing.

What a practice manager asks on the first call, answered from the same numbers as the rest of this page — 12 suites, 22,874 square feet, and a completion date.

What size suites are available?

12 suites, from 845 SF up to 3,587 SF as a single space, and 22,874 SF in total across all four floors. Two adjoining pairs can be taken as one space: Suites 110 and 120 for 4,369 SF, and Suites 405 and 407 for 2,901 SF. Rates are negotiable and quoted on request.

Is any of it already built out for medical use?

Suite 203 is. It is 1,383 SF on floor 2, already drawn, specified and permitted as three exam rooms, a lab, a private office, a waiting room and reception, and it is delivered finished — flooring, paint, doors, casework and countertops installed with the rest of the building's work, with no allowance to negotiate and no drawings to commission. Every other suite is an existing partial office build-out, refit to a signed plan, with the landlord's work scoped and priced in the lease.

What is the parking like?

79 spaces at 4:1,000 — four spaces for every thousand square feet leased. It is all surface parking at grade, at the door, so a patient parks and walks straight in; there is no deck and no ramp to climb. The drive court and the parking are rebuilt as part of the repositioning.

What hospitals are nearby?

UChicago Medicine AdventHealth GlenOaks is 2 miles away, and Ascension Alexian Brothers is under 7 miles away. The I-355 four-way interchange is at Army Trail Road, so patients and staff reach the door from the expressway rather than across town.

When does the renovation finish, and can I lease before then?

Construction begins September 2026 and the work completes in 2027. Suites are available now and leases are being signed now — a practice that signs before the work starts is not leasing the building as it stands today. The $5 million repositioning rebuilds the atrium, the corridors, the restrooms, the elevator cabs, the entry and the drive court around the tenant, on the owner's budget and to a fixed completion date, and the practice opens its doors into a finished building.
