Custom home renovations and additions

Working with Windhill + Co. on Your Next Home Renovation or Addition

From antique farmhouses to 90’s spec houses, we work with you and your design team to change the existing plan, structure, style and details of your home. Our clients have entrusted us with the careful period restorations, re-imagined “new-old house” renovations and completely contemporary additions to architecture, old and new. Often, a kitchen remodel or bathroom redesign begins the process, with other adjacent or supporting spaces – mudrooms, primary suites, kids bunks and great room/family rooms– organically following the re-creation, expansion or addition of those main living spaces.

Our Renovation Process is Tried + True

In New England, we have celebrated a changing architectural landscape for hundreds of years. Working in these communities, our builders are skilled at the process of adding and renovating spaces in homes of all ages, bringing structures and systems up to current standards and re-imagining those spaces to the delight of the homeowners we serve.
