Stand on the rooftop deck at 550 Westlake Park Boulevard on a weeknight evening and you're looking down at treetops that belong to Terry Hershey Park, at the taillights strung along I-10, and at a 19-story tower that spent nearly four decades as office space for BP and ConocoPhillips. A year ago this address had nobody in it after 6 PM. Now it has 311 apartments, a rooftop pool, and residents who never worked a day in the building they live in.
That's the Energy Corridor's real experiment right now, and it isn't happening in a boardroom. The district has spent its whole existence organized around a daytime population: over 26 million square feet of office space and enough capacity for more than 105,000 workers who arrive by 9 and clear out by 6. The trail, the restaurants, the events calendar, all of it grew up serving people who were passing through on a workday, not people who go home there at night. The Watt is the first building in the district's history built to test whether that infrastructure works for residents too, and the last twelve months of local news are the early results.
Why this happened here first
The math behind The Watt explains why the Energy Corridor, of all places, got Houston's first suburban office-to-residential conversion. The tower was bought at online auction in 2022 for $21 million, roughly $50 a square foot, a price far below what it would cost to build the same structure today. DeBartolo Development then spent $93.3 million converting it, and according to the firm's own numbers, a conversion like this runs about $300,000 per finished unit, compared with more than $500,000 a unit for new ground-up construction. The corridor also happens to carry the second-highest concentration of 4- and 5-star office towers in Houston, behind only downtown, a legacy of the construction boom during the shale era. Put those two facts together and you get a lot of well-built, aging towers sitting in a district where land is scarce and demand for apartments is real. The Watt is the proof of concept. Nobody in the district has done a second one yet.
Energy Corridor District President Bryan Brown put the shift in plain terms when the building opened:
"The Watt is a welcome addition to our neighborhood. It offers a new option for employees who want to live near their work. And it's already bringing in a new demographic to the area."
The building's community manager, Natalie Weldon, described the difference from downtown living more bluntly: "It's quieter here." That's the whole pitch in three words, and it's also the open question. Quiet is easy to sell. Whether quiet plus a corporate campus adds up to an actual neighborhood is what the next few years will show.
What's now walkable that wasn't a year ago
For the households already living in the corridor, the honest answer is that not much changed on day one. What changed is what opened around them since.
- Kirkwood opened in May 2026 inside Energy Tower II on Katy Freeway, a clubhouse-style restaurant from Mac Haik Restaurant Group with a domed entryway referencing Haik's touchdown in the original Astrodome and a menu built around pork chops, steak frites, and tableside carving. It gave the district something it had been missing: a sit-down destination with atmosphere, not just a lunch spot for people on a badge.
- EnergyFest, the district's free spring community festival, ran again this year with an Energy Stage for live music, a Family Village for kids, and a food truck marketplace, the kind of event that used to exist mostly to give tenants something to do at lunch and is now being marketed toward the people who actually live nearby. The organizers are already branding the next one EnergyFest 2027.
- The Energy Corridor Tree Lighting, sponsored by ConocoPhillips and CITGO every December, is the district's other recurring civic anchor, and it reads differently when some of the people attending walked over instead of driving in.
- Memorial Drive, between Highway 6 and North Eldridge Parkway, spent this past winter under a resurfacing project. The district's own construction updates had the work progressing lane by lane from January through a target completion of March 2026, the kind of unglamorous infrastructure detail that matters more to someone who drives that stretch every day than to anyone just passing through.
None of these are dramatic on their own. Together they're a district quietly building a resident-facing layer on top of an employer-facing one.
The trail was always the good part
If there's one thing the Energy Corridor never had to invent, it's the trail. Terry Hershey Park runs more than 11 miles along Buffalo Bayou across its 496 acres, according to Harris County Precinct 4, which maintains it, stretching from Beltway 8 out to Highway 6 and connecting on its west end to George Bush Park. The trail is named for Terry Hershey, who in 1966 stopped the Army Corps of Engineers from stripping the bayou's banks bare for straightening and paving, a fight that eventually earned her a description from George H.W. Bush as a force of nature.
That history matters here because it's the reason The Watt's rooftop pool has anything worth looking at. The building's marketing leans hard on views of the park's treetops, and that's not incidental. The trail was built for anyone in the district who wanted to run at lunch or bike home before traffic. It works exactly the same way for someone walking down from a 19th-floor apartment at 7 PM. The infrastructure didn't change. Who's using it as their everyday routine instead of their occasional break is what's different.
What this actually means if you live here
None of this settles the question of whether the Energy Corridor becomes a real neighborhood in the way Houston understands that word, with restaurants that stay open past 9, sidewalks people actually use, and a events calendar built for families first. What it does show is that the pieces already existed. The trail was there. The office towers were there, some of them now cheap enough to convert. The corporate sponsors that already fund the Tree Lighting and EnergyFest were there. What was missing was residents whose only relationship to the district wasn't a badge and a parking garage, and that's the piece The Watt is testing.
If it works, the economics that made this conversion make sense, the below-replacement-cost acquisition, the per-unit savings over new construction, apply to plenty of other 1980s and 1990s towers still standing along the Katy Freeway. If it doesn't, the district goes back to being what it's been for 45 years: a place people work and leave. Either way, the next eighteen months of restaurant openings, festival attendance, and whether anyone builds a second conversion will tell you more about where this district is headed than any press release will.
