If you're seeking an accomplished and responsive resource for your next commercial project, LLP Construction Services brings numerous advantages to the table, among them:

  • A passion for building in Detroit. Headquartered in Corktown, we're currently working on several projects within the city. We are well familiar with Detroit's permitting processes, and enjoy excellent working relationships with its building inspectors.
  • Responsiveness. Many of our clients are surprised at the quickness with which we can launch a new project. Of course, the same commitment applies to the way we assemble budgets, create proposals, answer your inquiries and address any issues as they arise. 
  • A fresh and unique approach. With an extensive background in design as well as construction, we deliver a unique and beneficial point of view to any endeavor. Like few others, we can take your project from initial concept all the way through to completion and close-out. 
  • A "won't-say-no" attitude. While many others won't consider smaller projects, we tackle them with the same enthusiasm as we do larger ones. Count on us for jobs no matter the size or complexity. 
  • Expertise spanning all areas.  From our headquarters in Detroit and office in Troy, we serve clients in Southeastern Michigan and beyond. Trust us for general contracting, construction management, design-build, pre- and post-construction as well as space planning and design services. 
  • Woman ownership.  Founder and President Lisa Petrella has more than 20 years of experience in the construction services industry, and is an active member of the National Association of Women in Construction (NAWIC) and Commercial Real Estate Women in Detroit (CREW).
