Boutique residential & commercial · Nashville
Close to the work. In the design conversation. Details executed with rigor — for the clients, architects, and developers who care how it's built.
A boutique builder with taste and real systems.
Mast stays close to the work, participates in the design conversation, and executes details with rigor. Independent, not corporate — the kind of partner clients, architects, designers, and developers trust to protect the investment and bring the vision to life.









Nearly fifteen years of building and development in Nashville.
Mast grew out of North by Northeast Development, co-founded by Steve Mabee in 2012 — more than 100 homes and $50 million in commercial assets built along the way. Today the studio carries a track record approaching $100 million in real estate development, with strategic relationships across architecture, land planning, and banking, and deep experience in proformas, construction, and sales. From small infill residential to commercial and retail, we handle projects of any size from consulting to development leadership.

Steve moved to Nashville in 2001 for the music industry, then transitioned to real estate in 2006, refining his investment expertise as an affiliate broker. Co-founding North by Northeast Development in 2012, he has managed a wide range of construction projects from Nashville to 30A and Pensacola. His diverse experience and passion for development and construction continue to drive Mast's work today.

A Belmont University graduate in Business Administration, Janelle began her finance and accounting career in 2017 at MW Real Estate, where she built transparent financial systems that fueled the company's growth. She brings that same discipline to Mast — maintaining financial health and the clear, no-surprises reporting our clients rely on.

Working with Mast Building Company was an excellent and enjoyable experience. They provided personable and thorough service throughout the entire experience of building a home. They exceeded our expectations every step of the way and we could not be happier with the outcome.
I had the pleasure of working as the designer with MAST on a home construction project. Throughout the process they were incredibly communicative and always kept me updated on the progress. MAST took the time to understand my vision and helped translate it into reality. Their oversight not only fostered a cohesive work environment but also built a collaborative partnership that enhanced the overall success of the project. The end result exceeded my expectations and I highly recommend MAST Building Co!
We are beyond satisfied with the exceptional workmanship and dedication of the Mast Building Company team. They transformed our vision into a breathtaking home that exceeds our expectations.
I have experience working with Steve Mabee on the design, budgeting and construction of my home. He does an excellent job making sure the homeowner is informed about the process and timeline and makes the numbers easy to understand. The finished product is excellent too!
