Adding Value to Your Home with a Custom Addition

Adding value to your home through well-planned additions not only enhances your living space but also significantly increases your property's market value. Home additions, whether it's an extra bedroom, a luxurious bathroom, or a spacious kitchen, cater to both the current needs of homeowners and the future prospects of homebuyers. These additions are especially impactful in areas like Elm Grove and Menomonee Falls, where homeowners seek to blend comfort with value.
For instance, kitchen additions are a prime example of how functionality and aesthetics can come together to boost a home's appeal. Renovating kitchen countertops, incorporating a functional kitchen island, and installing energy-efficient appliances are popular upgrades that resonate with modern buyers. A well-executed kitchen remodel, overseen by experts like those at Advantage Design + Remodel, not only makes the kitchen a centerpiece of the home but also adds substantial value. According to a study, certain home additions like a midrange primary suite can return about 30% of their cost, with a wood deck addition even reaching a 50% return.
Bathroom renovations are another aspect where thoughtful investments can pay off significantly. Transforming a bathroom into a spa-like sanctuary with high-quality tiles, fixtures, and smart features not only enhances the homeowner's experience but also appeals strongly to future buyers. Similarly, finishing a basement or adding a second story to a garage creates additional living or recreational space, increasing the overall functionality and appeal of the house.
Advantage Design + Remodel, with its strong focus on craftsmanship and customer satisfaction, ensures that these custom home additions not only meet the immediate needs of the homeowners but also strategically increase the property's value. Their design team's attention to detail and commitment to quality workmanship ensure that each remodeling project, be it a kitchen upgrade or a bathroom overhaul, contributes significantly to the home's market value.

Home Addition Contractors Aren't Created Equally

Just about every custom home addition contractor claims they're the best, most experienced contractors in the area. Some will even show you pictures of their successful projects and share the positive reviews they've gotten from clients. But, how do you know if they're being honest or if they're just saying what they think you want to hear to get you to sign on the dotted line?
The truth is, sometimes you can't tell until it's too late. You have to be very careful when choosing a contractor and that means doing your own research.

Hiring a contractor or DIY?

Before we can move forward, we believe it's vitally important that our entire team of dedicated tradespeople visits your home.

Common Questions

Addition remodeling questions

How long does an addition remodel take?+
Most home additions run 8 to 16 weeks once construction starts. The timeline accounts for ordering and lead times, plus key milestones with updates throughout.
Will I know what my addition will look like before construction?+
Yes. You review Chief Architect drawings and 3D renderings during design and development, and key decisions are finalized before the job starts.
Who handles permits, plumbing, and electrical?+
We do. As a design-build firm, you will not need to hire a designer, architect, general contractor, plumber, or electrician separately. One team, one point of contact.
Can I stay in my home during the remodel?+
Almost all of our clients do. We set containment, floor protection, and daily cleanup standards, and use HEPA air filtration to manage dust.
