Homeowner Reviews

  • BCIN designer 3d model of a Third floor addition

    Project: Third Storey Addition, Interior & Exterior renovations (Entire house), Basement Secondary Suite, Minor Variances Approved

    “Mark is an effective communicator and provided great service from the day I signed up to the day I received my second set of building permits over a year later. Mark came up with creative solutions for the open concept design I wanted as well as the approach I should take with the city in order to start work on the building quicker. Mark was also an invaluable part of the Committee of Adjustments (“CofA”) process. He diligently prepared the case and did a great job of representing my project and he was successful in obtaining a minor variance for the third floor addition and basement apartment portion of the project.” Nevin S. -⭐⭐⭐⭐⭐

    Project: New construction of 2 Storey Single Family Dwelling (3800sqft), Niagara Escarpment Commission Approved

    Mark H Smith guided our journey to build our new home, from start to finish. From listening to our needs, wants, evaluating options, to concepts, budget realities and all permits. The permitting process was complex being in a special development zone of the Niagara Escarpment.

  • BCIN designer 3d model of a new porch addition

    Project: New porch Replacement, Minor Variances Approved.

    Mark did an excellent job transforming our desire for a new front porch into a design that we loved. He took care of everything including liaising with the city and obtaining a building permit.

    Mark was a pleasure to deal with because he listened closely and used his expertise to satisfy all our wishes. Tony L. -⭐⭐⭐⭐⭐

  • BCIN designer 3d model of a Second Storey Addition

    Project: Second Storey Side Addition, Rear Second Floor Balcony, Interior Alterations, Minor Variances Approved.

    I retained Mark to design a 2nd story addition above a tandem garage. Mark efficiently guided through the Committee of Approval and Building Permit process despite a few miscues/delays from the City. Mark is very diligent and through, I would highly recommend his services, in so much that I already have lined him up for another project down the road. Bryan M. -⭐⭐⭐⭐⭐
