Mercury One plans $7.4M tenant build-out at Irving office

Mercury One Inc. is the named project on a $7.4 million build-out registered Oct. 28 with the Texas Department of Licensing and Regulation for 6655 N. MacArthur Blvd. in Irving. The filing covers an alteration of about 24,478 sq ft on the building’s second level, with office, assembly and support space.

Why it matters

The registration marks the work as paid for by the tenant, not the landlord. That puts Mercury One’s own money behind a $7.4 million fit-out, a commitment that points to long-term occupancy rather than a short stay. For Irving office landlords, it is a recorded example of a tenant carrying its own improvement costs. For contractors, it is an interior job already underway by the filing’s own schedule.

The numbers

The TABS record, TABS2027004586, lists an estimated cost of $7,444,351 for the 24,478 sq ft alteration, about $304 per sq ft. The building owner of record is Orion Irving TX LLC, with a Phoenix address. The estimated start is Oct. 9, 2026, nearly three weeks before the registration date, and the completion target is April 2, 2027. No tenant entity is assigned in the filing’s tenant field; Mercury One appears as the project name.

What’s next

The next record to watch is a city of Irving building permit for the address, which would name the general contractor and confirm the schedule. Any announcement of what Mercury One will run from the space would show how the assembly area is used. More Dallas-Fort Worth office and build-out activity is tracked on the market hub.
