Flex and Light Industrial Construction in Denver, Colorado

Small-bay flex space turns on the width of a bay, not the size of the building. A tenant who assembles electronics, stores trade materials or runs a showroom with a back shop wants a 30 to 60 foot bay, one or two dock or grade doors, 18 to 24 feet of clear height and an office that fronts the street. A developer who gets those dimensions right can lease the building in slices, and one who misses them ends up with a box that only suits one tenant.

Metro Denver has a deep flex stock and a strong appetite for more. 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. When vacancy sits that low, a new building that delivers on time can lease before the roof is on, which puts pressure on the construction schedule from the first month.

We build flex and light industrial for owners who want a repeatable, leasable product: clear spans, dividable bays, shared yard and parking, and mechanical and electrical systems that expand as tenants move in. Our light manufacturing and flex industrial work covers shell, site and tenant fit-out as a single program.

Infill sites, old uses and new demand

Flex growth in the metro often happens on land that has already had a use. The business park along the Santa Fe Drive corridor in Sheridan, bounded by Santa Fe Drive, West Oxford Avenue, West Union Avenue and the South Platte River, includes auto salvage, a recycling center, a lumber yard, auto repair and light manufacturing uses, and the city planned Phase 1 and Phase 2 environmental assessments of its parcels through EPA's Targeted Brownfield Assessment program to estimate remediation costs. That is a brownfield reuse story, and it is a common path for new flex space.

Federal Heights offers a different kind of opportunity. A 34.87-acre parcel along Federal Boulevard (U.S. 287), the last undeveloped part of the former Ruston Field airport, is offered for sale with more than two-thirds of a mile of frontage near the 104th and Federal retail area. A site like that supports a campus of flex buildings with visible frontage. We evaluate infill parcels against the cost of site clearance, environmental work and utility upgrades, so the buyer sees the full budget before committing. Our teams know both Sheridan and Federal Heights permitting.

Flex configurations we build

Flex is a family of buildings, not one design. A rear-load building has docks on the back wall and offices in front, a front-load building places grade doors on the street side for contractors and showrooms, and a cross-dock configuration allows truck access on both sides. We also build warehouse-office hybrids with mezzanine offices over the shop and light assembly buildings with higher power and compressed air.

The structure follows the use. Tilt-wall construction suits larger flex buildings with long, repetitive bays, and tilt-wall buildings are common where a developer wants durability and fire resistance at a reasonable price. A pre-engineered metal building suits smaller footprints, faster delivery and owner-occupied projects. We provide cost and schedule comparisons so the choice is made on numbers.

Dividing a building so tenants can move in

The costs of dividing a building appear after the shell is complete. Demising walls need a fire rating, plumbing and electrical need separate meters, and each suite needs its own HVAC, restrooms and access to a door. Planning the shell for division means stubbing utilities at the right spacing, leaving the slab undisturbed and placing column lines so partitions land in the right place.

Parking and truck circulation also constrain the design. A flex building in a small parcel has to fit car parking for the office and showroom component, trailer access for a delivery or two a day and a fire lane. We study turning radii and parking counts during site planning, because rework after the plat is approved is expensive. Our small-bay contractor condos experience helps when the buildings are sold by the unit and the demising must follow property lines.

Where flex budgets are won or lost

A flex project is a repeatable building, and the budget turns on the small decisions that repeat dozens of times: slab thickness, door counts, sprinkler layouts, office finishes and mechanical rooftop units. We offer a base building package and a short list of upgrades so the developer can price a spec building quickly and then decide where tenant-specific money should go.

Site work carries more of the budget than most developers expect, especially on infill. Retaining walls, utility relocations, stormwater detention and off-site improvements required by the city can equal a meaningful part of the building cost. We price industrial tenant improvements separately from the base building so the allowance and the actual fit-out can be compared line by line.

Building for the first tenant and the fifth

We design the shell so that the third and fifth tenants do not have to pay for the first tenant's mistakes. That means oversizing electric service where the cost is low, leaving space on the roof for added mechanical units, running a main sprinkler header that can accept a different commodity class and keeping the floor slab thick enough for racking. These are inexpensive at construction and costly later.

We also manage the leasing calendar. If a pre-leased tenant takes the first suite on a given date, we release that suite for fit-out while the rest of the building is still being finished, and we use temporary partitions and separate access so tenants can move in safely. The result is a building that earns rent before the last suite is done.

Flex corridors we know

The Denver flex market has several distinct corridors. The north metro, including Thornton, Westminster and Commerce City, favors larger distribution-oriented flex with easy access to I-25 and E-470. The inner ring, including Sheridan, Englewood and Federal Heights, favors smaller bays and mixed uses with trades and light manufacturing, often in older industrial zones. The western suburbs favor employment and technology flex close to U.S. 36 and I-70.

Each corridor has its own zoning, utility providers and market. We plan from local experience, and our work for logistics and distribution tenants who use flex space as a last-mile node, such as parcel carriers and e-commerce sellers, shows how the same building type adapts to different uses.

Common Questions

How wide should a flex bay be?

Most tenants want between 30 and 60 feet, with clear height of 18 to 24 feet, though the right dimension depends on the tenants you expect. Narrower bays suit trades and showrooms. Wider bays suit light assembly and storage. We help you test a layout against real tenant needs before drawings are final.

Can you build on a site with previous industrial use?

Yes, with environmental diligence first. The City of Sheridan planned Phase 1 and Phase 2 environmental assessments for its Santa Fe Drive business park to estimate remediation cost, which is the right model: assess early, price the cleanup and then decide. We coordinate with environmental consultants and handle soil management during construction.

How do I split a building into condo units?

The shell is designed with separate utilities, demising walls and access for each unit, and the plat and declarations follow. Fire ratings between units and separate meters are the main design items. We work with your attorney and engineer to make the construction match the legal documents.

What does a low vacancy rate mean for construction?

It means tenants are waiting, and schedule is worth money. Westminster reports a 2.4 percent vacancy for industrial and flex space, so an owner who delivers early can capture rent. We focus on long-lead items, permit coordination and phased turnover to protect the date.

Can flex space handle light manufacturing?

Yes, with the right power and ventilation. Light manufacturing often needs three-phase power, compressed air, exhaust and floor drains, and the building should be designed for them from the start. We review the tenant's process and tune the base building.
