Andrew B. Ashforth leads A.P. Construction, serving as the Co-Chief Executive Officer of The Ashforth Company and the CEO and President of A.P. Construction Company.

Gilbane Building Company

1055 Washington Boulevard, Stamford, CT 06901

Gilbane Building Company stands out in this list as one of the most experienced in the construction business at Stamford. A family-owned organization, Gilbane Building Company has over 150 years of experience, providing integrated construction and facility management services from many offices in the U.S. and overseas. 

Gilbane Building Company was established in 1870 as a carpentry and general contracting shop and has since built a solid brand as a leading construction firm that offers services ranging from sustainable building to applying the latest construction technology for clients across a range of markets. At present, the company is led by Thomas F. Gilbane Jr., a fourth-generation Gilbane family member with a background in Business Administration and Civil Engineering from Harvard and MIT. 

One great example of the company’s proven handiwork is the Slate School project featured below.

Pavarini North East Construction

30 Oak Street, 3rd Floor, Stamford, CT 06905

A result of that commitment is this Hildene Capital Management project in Stamford. Standing at 6,400 square feet, this loft-like space in a modern building was designed by Bavier Design and built by Pavarini North East. Some of the key features added to the building are the gorgeous white-washed brick, the reclaimed wood millwork and beams, the polished concrete floors, the raw metal topped with colorful antiques, and some unique seating.
