OWNER/BUILDER
“I first met with Jeff with just a concept in my head for a building to include a workshop/garage and a one bedroom apartment. Jeff started with a simple paper sketch and he and his small crew went from there and completed the building shell to perfection. Jeff and his team are easy to work with well organized and trustworthy. I couldn’t be happier with the final product and as such I hired him back the following year for a small but high impact mudroom project. I highly recommend Jeff for any construction new or renovation project you have in mind.”
