Room Addition Contractor San Antonio

If your home feels tight but you love your neighborhood, a small room addition can solve your space problem without the stress of moving. Rhino Design Build is San Antonio’s trusted contractor for custom home additions with more than 21 years of residential design and construction experience.

Why Add a Small Room Instead of Moving

A small room addition increases your home’s value and functionality. Whether you need an extra bedroom, office, playroom, or in-law suite, expanding your existing home gives you more living space while keeping your property taxes and mortgage in check. Homeowners across San Antonio are turning unused patios, garages, and attic space into comfortable new rooms that blend perfectly with the original structure.

  • Bedroom additions for growing families
  • Home office or study additions for remote work
