Greenhouse Office Park

Greenhouse, a Class A office building, is one of a few 5-story buildings constructed using tilt-up concrete panels. The majority of these panels weighed more than 200,000 pounds each and were 11 3/4″ thick.

Hoar broke ground on the first of two buildings planned for the Greenhouse Office Park in June of 2014. Greenhouse was built as a speculative, Class A office building at the western edge of Houston’s expanding Energy Corridor, so the owner wanted to accelerate speed to market to maximize return on investment. Tilt-up concrete construction allowed for an owner-mandated 10-month construction schedule from start to finish of the building’s core and shell. Greenhouse is one of few 5-story tilt-up projects. The 4+1 design (four-story panel plus a one-story panel welded together) consisted of 64 total panels, including the largest panel of 58’-11” x 32’-5” x 14 1/2” thick. The majority of the panels weighed more than 200,000 lbs. and were 11 3/4” thick. A 350-ton crane was used to lift the panels into place. The office building received LEED Silver certification.
