“How many bedrooms and bathrooms do you need?”
“What kind of layout supports your lifestyle?”
“Are you prioritizing entertaining space, privacy, outdoor living, or water views?”
“What architectural style feels most like home to you—modern, traditional, coastal, farmhouse?”
Creating a vision board or keeping a digital folder with inspiration can help when discussing plans with your design team.

- Topography and soil conditions: These can impact design and foundation requirements.
- Waterfront restrictions: Building near wetlands or on the shoreline may involve extra permitting.
Buying land with guidance from an experienced architect or builder can save you from unexpected challenges during construction.
