Tyler McIlroy


Co-owners, Kevin Bartman and Tyler McIlroy, believe that a hands-on approach produces the best results. When construction begins, they are both regularly on site carrying out the work with their own hands to ensure that every detail conceived in the design stage is crafted to perfection. Ingenuity, modernization and efficiency define their approach to business management, allowing them to spend less time doing paperwork and more time face-to-face with their clients. With over 20 years of combined experience in a diversity of construction fields, the duo is poised to lead the most demanding projects. 

Our process begins with gaining a detailed understanding of the client’s unique wants, needs and design preferences. Our team stays up to date on the latest in building science, materials, codes and trends to inform our clients of important factors to consider when choosing a design. Some clients know exactly what they want, while others need help conceptualizing a new vision for their space from the ground up. Whatever the case may be, we offer a full suite of design services that can be tailored to suit your specific needs and budget.

Our Process

Our Process



We take our time getting a thorough understanding of your vision and ideas for your home. Discuss budget and estimated job cost to see what's possible, and what improvements will add the most quality to your everyday life and home.



Determine your preferences and style. Assist in specifying materials, fixtures and other elements to be included in the design that embody your vision.  We provide 3D renderings and material samples to help guide you through the process.



Analyze how the project design fits within the your short and long term goals. Assist in refining the scope of work as necessary to preserve your budget and maximize value. Examine phasing to prioritize immediate needs while incorporating provisions for the future.



Foresee potential obstacles, minimize delays, and handle each phase of construction smoothly and efficiently. We guarantee reliability and quality with our work.



After project completion we bring in professionals for a thorough cleanup. Take you through a final walkthrough to ensure that every last detail is exactly as you want it. Our 2-year warranty will give you piece of mind for time to come.
