Work will begin this week on the most expensive downtown Dallas development in more than a decade.

The $250 million Hall Arts Residences condominium tower and Hall Arts Hotel will be a major addition to downtown Dallas’ Arts District.

The 44 condos in the 25-story tower on Flora Street will start in price at $2 million.

Hall Structured Finance (HSF) has provided a $23.2 million loan for the construction of a Hyatt House and Hyatt Place hotel in East Moline, part of the Quad Cities region. This will be Hyatt’s first development of a blended, dual-flagged hotel, with a shared front desk and lobby amenities, and will serve as the company’s prototype for future dual-flagged developments.

A California-based legal firm has moved its downtown Dallas office to the Arts District. Sedgwick Llp has rented an office in the KPMG Plaza building on Ross Avenue near Pearl Street.
