Custom Home Building

Expert craftsmanship and a professional project management process executed with a team approach will truly make your “dream home” an exciting, rewarding reality. We pay attention to detail, satisfying the most discriminating owner. Working with our design team or your architect from the earliest development stages, we assist in integrating systems (structural, mechanical, etc.) into your overall plan, refining your house into a special, custom-designed home.

Whole House Renovation

The more complex and detailed your renovation, the more you’ll value The Alexander Group experience. Our expertise takes the complicated and makes it look simple. With an eye for detail, we blend the new with the old for a seamless transformation, never cutting a corner. Major renovations with additions and whole house renovations are specialties upon which we have built our reputation.

Home Additions | Home Remodeling | Exterior Remodeling

Should we stay or should we go? Call The Alexander Group, before hiring a realtor and listing your home. See your home through new eyes. Sometimes your current home can be a “forever” home. A home addition could be a smart alternative to relocating. The Alexander Group will assess the best options—keeping the things you like about your home while integrating an addition that will create more space, improve interior traffic flow or even enhance your view of the great outdoors.

Home additions require careful architectural study. The finished product should seamlessly blend “old” and “new.” A neighborhood’s zoning regulations also require careful scrutiny when designing an addition. The Alexander Group will analyze constraints before embarking on a new design.

Looking to add a contemporary spin? It is possible to integrate the old and the new through analyzing your home’s proportions, scale, roof lines, materials and design details. An Alexander Group addition will never be a “box” tacked on to your existing home—a well executed addition can require as much time and design as a whole house renovation.

Kitchens & Baths

Clients have told us that we are more particular about the details than they are. We can help you create the look you want and obtain best value without sacrificing quality or service.
