Custom Interior Design
Evaluate interior design expertise across remodels, new construction, additions, alterations, furniture, and complete homes, with attention to timeless elegance and occupant wellbeing.
Choosing between local architecture and interior design services requires more than comparing portfolios. Look for a practice that can connect spatial planning, interiors, cabinetry, permitting, technology, sustainability, and construction guidance into one thoughtful process. This guide explains what to evaluate when comparing firms for custom homes, remodels, additions, and carefully coordinated residential environments.

Yes. Some architects provide interior design directly or coordinate it as part of a broader residential design service. Ortiz Mexia Projects, Inc. integrates architectural planning with interiors, furniture, cabinetry, and built-ins, helping maintain continuity between the structure and finished spaces.
