Benefits of Home Additions

Increased Living Space

Adding more square footage to your home transforms tight, confined areas into spacious, comfortable environments. Whether it’s a new bedroom, extended kitchen, or family room, a home addition gives you the freedom to spread out and create a layout that suits your lifestyle—without the stress and expense of moving to a larger house.

Improved Property Value

Well-designed home additions are a smart financial investment that can significantly boost your property’s resale value. Enhancements such as extra bedrooms, modern bathrooms, or expanded living areas appeal to potential buyers, making your home stand out in a competitive market. It’s a lasting improvement that increases both equity and desirability in the long run.

Tailored Functionality

A home addition allows you to create space that works exactly the way you need it to. Whether it's a guest suite for visitors, a dedicated home office, or a spacious playroom for kids, each feature can be customized to fit your daily life. The result is a home that functions more efficiently and personally for your household.

Seamless Aesthetic Integration

When thoughtfully planned and constructed, a new addition will complement your home’s existing style. Matching rooflines, siding, and architectural details creates a cohesive look that maintains your home’s curb appeal. A seamless blend ensures that your addition looks like it has always been part of the original structure—not an afterthought.

Cost-Effective Alternative to Moving

Selling your home and relocating can be time-consuming, stressful, and expensive. Building a home addition offers a more practical solution for accommodating your evolving needs. Whether you’re growing your family or need more space to work from home, additions let you stay where you are while gaining the benefits of a larger home.

Enhanced Energy Efficiency

Modern additions are typically built to meet or exceed today’s energy standards. With advanced insulation, energy-efficient windows, and updated HVAC options, you can reduce your energy consumption and lower your utility bills. Over time, the improved performance of your home not only saves money but also contributes to a more sustainable lifestyle.

Our Home Addition Services

Room Additions

We design and construct custom room additions tailored to your specific needs. Whether you’re looking to add an extra bedroom, a nursery, or a private office, our builds ensure comfort, functionality, and architectural harmony. Each space is designed to seamlessly match your existing layout while offering the versatility you require in your daily life.

Garage Additions

Our garage additions offer more than just vehicle storage—they can include upper-level lofts, workshops, or extra storage space. Whether attached or detached, these structures are built for durability, security, and accessibility. They not only protect your vehicles and tools but also add functional square footage that can enhance your home's overall value.

Sunroom Additions

Sunrooms bring the outdoors in while maintaining protection from weather and bugs. These light-filled spaces are perfect for reading, relaxing, or enjoying a morning coffee. Designed with energy-efficient glass and stylish finishes, a sunroom adds visual appeal, comfort, and a welcoming environment to your home year-round, no matter the weather.

Kitchen Expansions

Expanding your kitchen provides the opportunity to improve functionality, flow, and aesthetics. From increasing counter space and cabinetry to integrating better lighting and open layouts, we help make your kitchen more accommodating for cooking, dining, and entertaining. A kitchen expansion turns a cramped area into the vibrant hub of your home.

Bathroom Additions

Whether it’s a master en-suite, a guest bathroom, or a new powder room, adding a bathroom improves both daily convenience and property value. Our team focuses on efficient layouts, modern fixtures, and water-saving technology to deliver stylish, functional, and long-lasting results that meet your family’s needs and preferences.

Second Story Additions

If expanding outward isn’t an option, building up is a smart solution. Second-story additions double your living space while preserving yard area. These projects include architectural planning, engineering, and seamless integration with your current home. It’s an ideal way to accommodate more bedrooms, bathrooms, or even a full upstairs suite without relocating.

AH Construction did an awesome job rehabbing the outside of our house. Alvin's pricing was great. They redid everything on the outside of our house except for the wood on the side porch. Alvin's team doesn't mess around. They get to work and get it done right. I do not hesitate to recommend their work.

From start to finish Hostetler builders were professional and great to work with. Even in some harsh temperatures they worked hard to keep our project moving. My family has many years of experience in the building trades and were very impressed with their craftsmanship. We worked as a team to overcome some issues that developed towards the end and we couldn’t be happier with the final product. Huge thank you to Alvin and his crew for being a part of our build!!
