Shallow-bay flex space lives or dies on its suite layout, and the layout is fixed long before tenants sign. Column spacing, door positions, clear height, the depth of the building and the way utilities are stubbed into each bay decide whether the same shell can hold a machine shop, a lab, a showroom or a contractor yard. We build flex and light industrial buildings with that range of tenants in mind, so a suite can be demised, combined or converted without opening the slab.
Colorado supplies steady examples of the product type. Compark470 in Parker is two shallow-bay industrial buildings of about 133,133 square feet near Compark Boulevard and Chambers Road, with a groundbreaking reported on May 21, 2026, completion expected in Q1 2027 and access to E-470 and I-25. In Evans, three new industrial buildings at Brantner Road were built in 2025 near Highways 85 and 34 and I-25, with a 7,500 square foot first suite on offer. These are small by logistics standards, and the small footprint makes each decision about door counts, offices and parking matter more.
We take flex projects from site to tenant-ready suites. That includes site civil, the building shell, demising walls, stubbed utilities and a landlord finish package, and for buyers who want to deliver suites in finished form, the interior work follows through industrial tenant improvements. For owners who plan to sell small bays to end users, our small-bay contractor condos work covers the separation of utilities and the individual metering that a condo structure needs.
Designing a shell that tenants can reshape
The first step is a tenant study. We ask who the likely users are, what power each draws, how many overhead doors they want and whether they need a floor drain, a sink, a compressed air line or a yard. A suite built for light assembly needs three-phase power and a clear height of the right range; a suite for a trade contractor needs a drive-in door and a place to park a truck. The shell is detailed around the common denominators, and the exceptions are priced as upgrades.
We stub plumbing, electrical and data to the demising lines and leave sleeves through the slab and walls where future partitions will go. This costs a little at the start and saves a lot when the first tenant asks for a restroom group or a lab sink. The same approach to modular structure applies in a pre-engineered metal building frame, where bay widths and eave heights are chosen to fit the planned suites.
Why flex product keeps getting built
Westminster's 2024 economic profile reports 30 business parks and over 18.7 million square feet of commercial space, including 3,582,581 rentable square feet of industrial and flex space at a 2.4 percent vacancy rate in September 2023. A vacancy rate that low means a tenant looking for flex space has few existing suites to choose from. The product fits small and mid-size operators, including advanced manufacturing start-ups, that need a mix of office, light production and storage near a highway and a workforce.
The location pattern is clear. Westminster is served by I-25, U.S. 36, U.S. 287 and State Highways 95, 121 and 128, and the building sites in the corridor are close to the metro labor pool. Further north, the Northland Business Park off US 85 at Fort Lupton sold 316 acres in November 2024, including 103 acres of shovel-ready land across 15 parcels, which tells us land for smaller industrial buildings is also moving outside the core. Those sites often involve a longer utility run, and we price it from the first meeting.
The tenant mix a flex building can hold
Flex buildings commonly hold light manufacturing, electronics assembly, labs, e-commerce returns processing, trade contractors, equipment sales and service, and showrooms with warehouse space. Each of these has its own demands on power, ventilation, fire protection and floor drainage. We map the mix to the occupancy classification up front, because tenants in different hazard classes may need a rated separation or a limit on the area they can occupy.
If a building is mostly storage with a modest office, the economics resemble a warehouse at a smaller scale. If it is closer to a lab or a production floor, we apply the standards used in light manufacturing and flex industrial projects, including provisions for exhaust, process cooling and additional electrical capacity.
Delivering suites in a staggered sequence
A multi-building flex project can deliver in stages. We build the site civil and the first building, then release the second as pre-leasing or sales proceed. Because the last building shares the same detention pond, drives and utilities, we size those pieces for full build-out, and we stage the landscaping and paving so the first tenants have a finished entrance while later buildings are still under construction.
Weld County and the surrounding area add a structural step. Unincorporated Weld County adopted the 2024 International Building Code effective June 15, 2026, with engineered foundation designs required for most new structures. A geotechnical report and a stamped foundation design are part of the schedule for any site there, and we order the soils work during due diligence so that it is done before the entitlement clock matters.
Tell us how your tenants will use the space
Send the suite sizes, office ratio, door counts and the power each tenant type will draw. We will return a building layout and schedule that keep the suites flexible and the first tenant move-in date realistic.
Common Questions
What clear height should a flex building have?
It depends on the tenants. Many light industrial users want a height that supports racking, a mezzanine or an overhead crane, while office-heavy users are content with less. We ask for the intended users and then pick a clear height that suits them and still fits the roof and drainage design. Going taller adds to the frame and the exterior skin but keeps the suites flexible.
How many overhead doors per suite?
It is usually one drive-in door for every suite and one or more dock-height doors for suites that handle freight. We confirm the count with the leasing plan and match the doors to the truck types the tenants will bring. Extra doors can be added later in some wall systems, and we note where that is feasible.
Can the slab handle heavy equipment?
It can, if we know about it. A standard flex slab is designed for typical forklift and racking loads, and we can thicken or reinforce areas for heavier equipment. Telling us about heavy machine tools or presses at design time is cheaper than trying to modify the slab afterward.
What utilities do tenants usually need?
Three-phase power, water and sewer, gas where the tenant needs it, and data. We stub the services into each suite with capacity for typical users and note the limits. If a tenant needs more than the standard allowance, the upgrade is priced as a separate item so it does not slow the base building.
Do you work with owners who sell suites as condominiums?
Yes. Condo structures need separate utility meters, demising walls with the right fire rating and a plan for shared site elements such as drives and detention. We build to that structure and coordinate with the owner's attorney and engineer on the documents that describe it.
