The $500 million mixed-use project The Allen has marked two construction milestones: completion of the foundation core for its hotel-condo high-rise and the topping-out of its lifestyle pavilion, developers DC Partners announced Oct. 9.

The four-level, 62,000-square-foot pavilion is scheduled be ready for tenant move-in by the first quarter of 2021, while the high-rise is expected in 2023.

The pavilion is 80% leased, according to the news release, and will include a fitness club; rooftop dining with views of Buffalo Bayou Park; and retail and restaurant spaces.

The Thompson Hotel will take up the first 15 floors of the high-rise, and The Residences at The Allen will take up floors 16 through 35, offering 99 condominium residences, 17 penthouses and a rooftop helipad "engineered to accommodate drone deliveries and transportation of the future," according to the developer.

The residences are 20% pre-sold, according to DC Partners.
