Our Work





What questions should I ask
a residential general contractor when I want to build a custom home?
“Custom” can mean anything from changing minor details of your existing plan to from-scratch planning with your architect and design team. KCS Building Group will work closely with your architect and design team to ensure your vision becomes reality.
You do. When we create your budget and work plan, we’ll build in allowances for everything from countertops to deck lighting. The choices are up to you (and your designer, if you choose one), and can be as practical or as extravagant as your tastes and budget allow. KCS Building Group can help you decide which finishes and fixtures to splurge on, and where to keep it simple.
The land you choose has a major impact on the type of house you can build on it. Some neighborhoods have specific guidelines and covenants to follow, and some properties have physical features that determine what’s possible. KCS Building Group helps you make smart construction decisions based on your unique property.
Building a new or custom home is a big project with many moving parts. Make sure you understand exactly what your contractor’s estimate covers to avoid unpleasant surprises mid-project. KCS Building Group provides “total package” estimates. Everything you need—HVAC, plumbing, electrical, landscaping, and more—in one itemized proposal.
