A downtown office building selling at a steep discount may look like a warning sign. It can also signal that the market is finally moving forward.

In a new Denver Business Journal article, TRE Partner Amy Aldridge explains why recent office auctions can help accelerate Denver’s recovery. Reset pricing gives new owners the flexibility to invest in improvements, attract tenants and evaluate what each building should become next.

As Amy shares, some properties will remain offices. Others may be better suited for residential conversion or an entirely new use. What matters is getting them into the hands of owners with the capital and vision to take action.

TRE’s analysis found that removing “zombie buildings” awaiting conversion would lower downtown Denver’s office vacancy rate to 26.7%, offering a clearer picture of the active market.

The challenges are real, but so is the opportunity to reinvent these properties in ways that benefit downtown and the broader community.

New owners bring fresh perspectives — and fresh dollars.

Never underestimate a seventh grader with a follow-up question.

Last week, TRE Partner Andy Cullen returned to his former middle school, Columbia Middle School, through Big Brothers Big Sisters of Colorado’s Project AIM. The program introduces seventh-grade students to different career paths and the journeys that can lead them there.

Andy shared his experience in commercial real estate, answered questions and gave students an inside look at a career they may not have considered before. One student even asked what happens when you break a contract. We have a feeling there were a few future dealmakers in the room.

In DTC, not all office space is competing on equal footing. 🏢

With much of the market made up of buildings from a similar era, the differentiators often come down to amenities, views, floor plates, parking and the investment landlords are willing to make in their properties.

TRE Partner Andy Cullen shares what’s driving competition among DTC office properties and why both building quality and ownership strategy can influence where tenants have room to negotiate.

The headline vacancy number doesn’t tell the full story of the Denver Tech Center.

The southeast suburban office market spans roughly 40 million square feet with vacancy around 20%. But for Class A space, vacancy is closer to 6%, painting a very different picture of demand at the top of the market.

As companies continue to prioritize quality buildings, strong locations, views and amenities, the gap between the broader office market and the most desirable spaces is becoming increasingly important.

TRE Partner Andy Cullen shares his perspective on the flight to quality and what he’s seeing across DTC.

A workplace should do more than house a team. It should support how they collaborate, strengthen company culture and create an experience people want to return to each day.

We're proud to have partnered with Gary Community Ventures on a workplace that reflects their mission and supports the next chapter of their organization.

Take a walk through the finished space.

Every organization works differently, and so should every workplace. Gary Community Ventures wanted an office space that encourages collaboration, strengthens connections and reflects its mission of creating greater opportunity for Colorado kids and families.

TRE partnered with the Gary team from site selection and lease negotiations through construction and move-in to help make that vision a reality.

And hearing how the new space has impacted their team? That’s the best part. Thank you to Gary Community Ventures for trusting us throughout the journey.

Hear from their team and ours about the collaboration behind their new space in Downtown Denver.

Every swing had a purpose. ⛳

Andy Cullen represented TRE at the Big Brothers Big Sisters of Colorado Big Impact Golf Classic, joining Sean Campbell, Jason Hansen and Eric Hiraga for a day on the course in support of youth mentorship across Colorado.

Thank you to Big Brothers Big Sisters of Colorado for creating opportunities that extend far beyond the golf course.
