Project Details

Located on 8th Avenue in Altoona, PA, The Mill, which was originally built in 1889, is now a renovated mixed-use facility that will include office space, a café, a restaurant, and apartment units.

While several outbuildings and 80,000 square feet of the original building were demolished, 91,000 square feet was retained, in addition to an annex building and a 90′-tall smokestack that serves as an iconic landmark for the project.

Parking lots, a dining patio, sidewalks, street trees, lighting, and landscaping were all added. Stormwater detention was avoided by adding green space and amended soils to the site, which was previously 100% impervious.


We have worked with Keller Engineers for structural and civil engineering support on six projects over the past five years and have been very pleased with the results. Our projects tend to be complicated phased renovation/ addition projects calling for creativity in planning and construction.  I have been particularity pleased with their responsiveness to issues that arise during construction which is of particular importance to us and our clients.
