Our Home Addition Services

Room Additions

We design and build custom room additions, including bedrooms, living rooms, and sunrooms that enhance your home’s usability. Our team carefully considers natural light, ventilation, and layout to create open and inviting spaces. We also ensure energy efficiency and durable materials suited for the climate.

Kitchen Expansions

Expand your kitchen’s footprint to create a more functional and inviting space. We work closely with you to incorporate the latest design trends and smart storage solutions that maximize efficiency. Whether adding an island, breakfast nook, or extending prep areas, your new kitchen will be both stylish and practical.

Master Suite Additions

Add luxury and privacy with a custom master suite addition, complete with walk-in closets and spa-inspired bathrooms. Our design approach blends elegance with functionality, incorporating private balconies, sitting areas, or built-in storage features. We carefully select materials that enhance indoor comfort and reduce cooling costs.

Home Office Additions

Add a quiet, dedicated office space to support your remote work needs. We tailor the layout to optimize natural light and minimize distractions, ensuring a professional atmosphere at home. Whether you need a compact workspace or a full-scale office with meeting areas, we build spaces that adapt to evolving work styles.

Garage Conversions and Additions

Convert or expand your garage to add versatile living or storage space. Whether transforming the space into a guest suite, gym, or workshop, we ensure quality insulation and finishes to make it comfortable and functional. These upgrades not only provide extra square footage but also improve the overall usability of your property.

Outdoor Living Space Additions

Extend your home into outdoor patios, covered porches, or screened-in lanais. Our designs often include ceiling fans, built-in seating, and lighting to enhance usability during warm evenings. By blending indoor and outdoor spaces, you can enjoy natural beauty, fresh air, and social gatherings easily and comfortably.

Benefits of Home Additions

Increased Property Value

Larger, well-designed spaces attract buyers in a competitive real estate market. Quality additions not only boost your home’s appraisal value but also make it stand out in listings. This is particularly important as real estate continues to grow, with buyers looking for move-in-ready homes that offer space and modern features.

Customized Living Space

Home additions allow you to tailor your living environment to suit your needs, whether it’s a guest suite, expanded kitchen, or dedicated workspace. You can incorporate personalized design elements, choose finishes, and create functional layouts that a standard home rarely offers. As your family’s needs evolve, an addition gives you the flexibility to adapt your space without compromise.

Enhanced Energy Efficiency

By integrating modern materials and building techniques designed for the climate, additions can improve your home’s energy performance. These enhancements contribute to a more sustainable home and help lower monthly utility bills. Additionally, smart technology like programmable thermostats can be integrated to optimize energy use year-round, making your home both eco-friendly and cost-effective.

Preserve Neighborhood Charm

Rather than relocating, a thoughtfully designed addition lets you stay in your preferred neighborhood while modernizing your living space. Additions designed with sensitivity to local styles ensure your home remains harmonious with surrounding properties. This approach preserves your neighborhood's unique ambiance and cultural identity while giving you the modern comforts you desire.

Maximize Outdoor Living

Many homeowners choose additions that open up to patios or courtyards, blending indoor and outdoor living. Outdoor additions often include features like built-in seating, fireplaces, or shade structures to extend usability. Creating seamless transitions between interior and exterior increases your home’s livable space and fosters a connection with the natural environment.

Avoid the Cost and Hassle of Moving

Expanding your home with an addition saves you the financial and emotional cost of moving. Moving can disrupt family routines, require significant upfront costs, and come with uncertainty about new neighborhoods. An addition lets you stay rooted in the community you love while upgrading your living environment efficiently and comfortably.

Frequently Asked Questions

  • How long does a typical home addition project take in Phoenix?

    Most home addition projects in Phoenix take between 8 to 16 weeks, depending on scope and permitting. Seasonal factors, like monsoon rains, can influence timelines, but experienced contractors plan accordingly to minimize delays. Proper planning and communication help ensure your project stays on schedule despite weather challenges unique to the Phoenix area.

  • Do I need permits for home additions in Phoenix?

    Yes, all home additions in Phoenix require permits to comply with Maricopa County and city regulations. Professional remodelers ensure all permits are secured before construction begins to avoid legal and safety issues. Securing permits also guarantees that your addition meets local building codes, which protects your investment and property value.

  • How can I ensure my addition matches my home’s existing style?

    Skilled design teams analyze your home’s architecture and materials to create additions that complement your existing style. Local knowledge of Phoenix’s architectural trends is crucial for seamless integration. Designers also consider neighborhood aesthetics to maintain harmony with surrounding homes, preserving community character.

  • What energy-efficient options are available for home additions in Phoenix?

    Options include high-performance windows, insulated walls, solar shading, and energy-efficient HVAC systems designed to reduce cooling loads during Phoenix’s hot summers, improving comfort and lowering utility bills. Additionally, incorporating smart home technology can optimize energy use and further reduce your environmental footprint.

  • Can I add an outdoor living space as part of my home addition?

    Yes, many Phoenix homeowners incorporate patios, lanais, or covered porches to enhance indoor-outdoor living. These additions take advantage of Arizona’s mild climate for year-round enjoyment. Features like ceiling fans, pergolas, or shade sails can be added to improve comfort during warmer months.

  • How much does a typical home addition cost in Phoenix?

    Costs vary widely based on size, design complexity, and materials. On average, Phoenix home additions range from $80 to $200 per square foot. After an initial consultation, detailed quotes provide transparency and help you budget effectively for your specific project needs.

  • Will a home addition increase my property taxes in Phoenix?

    Generally, yes. Adding square footage typically increases property value, which can lead to higher taxes. Consult with your local assessor’s office to understand potential impacts before starting. However, the increased value often outweighs additional tax costs through enhanced living space and investment potential.

  • Are there financing options available for home additions?

    Many Phoenix lenders offer home equity loans, lines of credit, or construction loans for additions. We recommend trusted financial partners to help fund your project responsibly. Exploring financing early allows for better planning and ensures your home addition proceeds smoothly without financial stress.

I hired Spice Girl LLC after I had major flooding throughout my home. They have been nothing but professional and knowledgeable about the work that will need to be done, as a result of all the water damage throughout my home. I will gladly refer them time and time again! Lastly, their eye for design is beyond valuable! They listened to my vision for my new kitchen and bathroom and we are designing now. Will follow with another review and pix upon completion.

Erika and her team remodeled our house in north Scottsdale. She was always on time, offered design input when needed, and managed the project even while I was remote. Her team worked hard, finished in the proper timeline and were within the budget we discussed. What more could you ask for?!! Definitely would recommend and use again!

After months of looking for a contractor that I felt I could trust and understood my taste to remodel my master bathroom I found Spicegirls. Loved the concept that they are a women run business. I do not live in the US at this time and in so all of our decisions, pictures ect. were done virtually. I was updated regularly. My bathroom has turned out beautifully. Highly recommend.
