Home Extensions

At Together Design & Build, we help homeowners in Austin, Dallas, and surrounding areas plan and build home extensions that feel natural, functional, and connected to the existing home.

Home Extensions Built Around the Way You Live

Many homeowners reach a point where their home no longer fits their lifestyle. The kitchen feels too small. The living room feels crowded. The family needs another bedroom. Work-from-home life requires a private office. Guests need a more comfortable place to stay. Moving may be an option, but it is not always the right one.

Home extensions allow you to expand your home while keeping the location, memories, and features you already value. Instead of starting over somewhere else, you can create the space your home is missing.

At Together Design & Build, we help homeowners think through what the extension needs to accomplish. Some home extensions are designed for more daily living space. Others are built for privacy, hosting, storage, or long-term property value. The right plan depends on your home, your goals, and how the new space should connect to the existing layout.

Home Extensions for More Living Space

Many homeowners choose home extensions because they need more space for everyday life. As families grow or routines change, the original floor plan may start to feel limited. A home that once worked well may now feel crowded, closed off, or missing key rooms.

A home extension can create the space you need without giving up the home itself. You may want a larger family room for gathering, a bigger kitchen for cooking and hosting, or a new bedroom for a growing family. You may want a private home office, a playroom, a guest suite, or a larger primary suite.

Our Home Extension Process

01. Consultation & Discovery

We begin by learning about your goals, budget, timeline, and how you want your home to function. This helps us create a clear vision for your home extension project.

02. Design and Planning

Our team develops the layout and design of the new space, ensuring it connects seamlessly with your existing home while selecting materials, finishes, and key features.

03. Project Planning & Proposal

Once the design is finalized, we define the scope of work, construction details, material selections, and project timeline so everything is clearly planned before construction begins.

04. Completion & Walkthrough

We manage the entire construction process from start to finish, keeping you informed along the way. After completion, we review the finished home extension, answer and make sure the details are complete.

Every project tells a story of transformation

Full home remodeling takes more than basic construction. It requires planning, design guidance, trade coordination, structural awareness, material selections, communication, and a strong understanding of how every space connects.

What Is a Home Extension?

A home extension is an expansion of your existing home. It can add new square footage, enlarge current rooms, or create a completely new living area. Home extensions can be built to the side, back, or top of a home depending on the property, structure, and project goals.

Home extensions may include:

Kitchen extensions
Living room extensions
Bedroom additions
Primary suite additions
Guest suite additions
Home office additions
Second-story additions
Garage extensions
Dining room additions
Family room additions
Sunroom additions
Bathroom additions
Multi-room additions
In-law suite additions
Outdoor-to-indoor living expansions

A home extension can be simple in concept, but it is not simple in execution. The new space needs to tie into the existing structure, roofline, foundation, exterior materials, interior finishes, electrical systems, plumbing needs, HVAC planning, and layout flow. That is why choosing the right home extension contractor matters.

Kitchen Extensions

A kitchen extension is one of the most common and valuable types of home extensions. Many older homes have kitchens that feel small, closed off, or disconnected from the main living areas. By expanding the kitchen, homeowners can create better storage, more counter space, a larger island, improved natural light, and a better flow for hosting.

A kitchen extension may include new cabinetry, countertops, flooring, lighting, appliances, plumbing fixtures, pantry space, and a more open layout. It may also connect the kitchen to the dining room, living room, or outdoor living area.

Together Design & Build helps homeowners plan kitchen extensions that feel both beautiful and practical. The kitchen should not only look better. It should work better every time you cook, gather, and live in the space.

Primary Suite and Bedroom Additions

Bedroom additions and primary suite extensions can make a home much more comfortable. A new bedroom may be needed for a growing family, visiting guests, or long-term household needs. A primary suite addition can create a more private and relaxing area with a larger bedroom, walk-in closet, and bathroom.

These home extensions need thoughtful planning because comfort, privacy, lighting, storage, and bathroom access all matter. A primary suite addition should feel like a natural retreat, not a room squeezed onto the back of the house.

Together Design & Build helps plan bedroom additions and primary suite extensions with the full home in mind. We look at how the new space connects to the existing layout and how it can improve daily life.

Home Office and Flex Space Extensions

Work, school, and daily routines have changed for many homeowners. A home office is no longer just a nice bonus. For many people, it is a needed part of the home.

A home extension can create a private office, studio, flex room, or quiet workspace that is separate from the noise of the main living areas. This type of home extension can be designed for focus, storage, video calls, creative work, or business needs.

Flex space can also change over time. A room that starts as an office may later become a guest room, hobby room, study, or extra bedroom. Together Design & Build helps homeowners think through both current needs and future use.

Second-Story Home Extensions

When a property does not have enough room to expand outward, a second-story addition may be an option. Second-story home extensions can add bedrooms, bathrooms, offices, bonus rooms, or an entire upper-level living area.

These projects require careful planning because they involve the existing structure, foundation, roofline, stairs, layout flow, and exterior design. A second-story addition needs to feel balanced and supported, both visually and structurally.

Together Design & Build can help homeowners explore whether a second-story home extension makes sense for their goals and property. This type of project is more complex, but it can create major new living space without taking away yard space.

Why Choose us for Home Extensions?

A home extension is a major project, and the team you choose matters. Together Design & Build is built for larger remodeling and construction projects that require planning, design, and strong project management.

We are not focused on small handyman repairs or basic installs. Our team is a better fit for homeowners who want to expand their home with a thoughtful plan and a finished result that feels complete.

Homeowners choose Together Design & Build because we connect design and construction under one process. This helps make home extensions feel more organized from the first consultation to the final walkthrough.

Design-Build Planning for Home Extensions

Home extensions involve many details. The design needs to fit the home. The structure needs to support the plan. The materials need to match or complement the existing finishes. The construction process needs to be managed carefully.

Together Design & Build uses a design-build process to bring planning and construction together from the beginning. This helps avoid the disconnect that can happen when design and construction are handled separately.

Frequently Asked Questions

How much does a home addition cost?

Home addition costs vary widely based on size, type, and finishes. Generally, additions cost more per square foot than new construction due to integration with the existing home. We provide detailed estimates during your consultation.

Do I need permits for a home addition?

Yes, home additions require building permits in Austin and Dallas. We handle all permit applications, inspections, and approvals to ensure your addition meets all codes.

How long does a home addition take?

Most additions take 3-6 months from start to finish. Timeline depends on size, complexity, permit approval time, and weather conditions.

Will the addition match my existing home?

Absolutely. We carefully match exterior materials, architectural details, and interior finishes so your addition looks like it was always part of your home.

Can I live in my home during construction?

Yes, most homeowners remain in their homes during construction. We minimize disruption by containing work areas, maintaining clean job sites, and coordinating schedules with you.

Do home additions add value to my home?

Quality home additions typically provide good return on investment, especially bedrooms, bathrooms, and functional living space. We design additions that appeal to your needs now and future buyers later.

What's better: adding on or building up?

Ground-level additions are generally less expensive, while second story additions maximize small lots. We’ll evaluate your property and recommend the best approach for your situation.

Do you handle HOA approval?

Yes, we prepare all necessary documentation and drawings for HOA approval and work with your association throughout the process.

We’re ready to make your vision a reality!
