Luxury Home Additions in San Antonio
Today’s homeowners are navigating a fast-changing housing market and a shifting economy, and the demand for more square footage has never been higher. If you are considering a home addition in San Antonio, Rhino Design Build specializes in creating custom living spaces that combine comfort, style, and long-term value.
Many older homes in the heart of the city were not built with the space modern families need. Whether your family is growing, your adult children have returned home, or you simply want a larger, more functional layout, a luxury home addition offers the perfect solution. Our expertly designed additions not only expand your living space but also increase your property’s value, making it a smart and timeless investment.

Types of Home Additions:

Room Addition:

A room addition expands the footprint of your home by creating one or more new rooms that increase the total square footage. With expert planning and design, your new space will flow seamlessly with the existing floor plan while maintaining the character and style of your property. At Rhino Design Build, we carefully match every detail, from architectural elements to construction materials, so the addition feels like a natural extension of your home.
Beyond the lifestyle advantages, a professionally designed room addition is also a powerful financial investment. Adding square footage not only provides the space your family needs today, it also increases your home’s appraised value and strengthens long-term resale appeal.

Attic Conversion:

An attic conversion is one of the smartest ways to transform unused space into valuable, livable square footage. Most homes already have a staircase leading to the unfinished attic, and with the right design, this area can become a functional extension of your home. Adequate ceiling height is important, and if additional headroom is needed, the roofline can be modified to achieve the desired design.
Working with a design professional ensures the new attic remodel meets building codes, flows seamlessly with your existing layout, and enhances both comfort and style. Beyond the lifestyle benefits, an attic conversion is also a strong financial investment. Adding usable living space not only increases your family’s enjoyment of the home but can significantly raise the property’s appraised value and long-term resale appeal.

King William Second Story Room Addition

Mother-in-law suites:

A mother-in-law suite or guest house can be built as an attached addition to your home or as a detached structure positioned at the side or back of your property. Often referred to as a father-in-law suite, granny flat, casita, accessory dwelling unit (ADU), or backyard cottage, these spaces function as private, self-contained apartments that provide both comfort and independence for family members, guests, or tenants.
In addition to their lifestyle benefits, these suites are a high-value investment. They significantly increase a home’s appraised value while also creating opportunities for rental income. Many San Antonio homeowners are taking advantage of the thriving short-term rental market by listing their new casitas or guest houses on Airbnb or VRBO, while others choose long-term leasing for steady monthly income. Whether for family, hospitality, or investment, a professionally designed guest house or granny flat adds both versatility and financial return to your property.

Second Story Additions:

A second story addition is an excellent way to expand your home’s living space without increasing its footprint. Often referred to as a two-story addition or 2-story add-on, this type of project typically requires the installation of a new staircase, a reinforced foundation, an upgraded floor system with I-joists, and a redesigned roofline. Because most homes were not originally engineered to carry the added weight of a second story, careful planning and expert design are essential.
The City of San Antonio requires both an architect and a structural engineer to provide detailed drawings and calculations as part of the building permit process. At Rhino Design Build, we handle every detail to ensure your second story addition is designed for safety, functionality, and style.
Beyond the lifestyle benefits, adding a second story is also a strong financial investment. By significantly increasing your square footage and improving your home’s curb appeal, a second story addition can dramatically raise the appraised value of your property and boost long-term resale potential. For many San Antonio homeowners, this project not only transforms their living space but also delivers one of the highest returns on investment in residential construction.
