New Home Additions In Santa Rosa

What Is a Home Addition?

A home addition is a construction project that involves adding new space to an existing home. This can be in the form of extra rooms, a floor, or an entire wing of a house. Adding new rooms to your home is a great way to increase your property value as well as usable space.

Our Home Addition Construction Process

The process of building a home addition typically involves the following steps:

  1. Planning: We will design your new space, obtain the necessary permits and approvals from local authorities, and hire any necessary subcontractors.

  2. Excavation: This usually means digging a foundation for the new addition, which may include pouring concrete footings and foundations.

  3. Framing: Whitney Homes tackles the process of building the frame or skeleton of the new addition, which may include installing floor joists, wall studs, and roof rafters.

  4. Electrical and plumbing: We install all of the necessary electrical wiring, outlets, and fixtures, as well as plumbing pipes and fixtures in your new space.

  5. Insulation and drywall: This involves insulating the walls, ceiling, and floor of the new addition, as well as installing drywall to cover the framing.

  6. Finish work: Our team of finish carpentry specialists will complete the interior and exterior finishes of the new addition. We take care of the final touches such as painting, flooring, trim work, and installing doors and windows.

It’s important to carefully plan and budget for a home addition, as it can be a complex and expensive project. It’s also important to hire a reputable and experienced contractor like Whitney Homes to ensure the work is done safely and to code.

Types of Additions We Do

Exterior Patio Enclosure and Sunroom Additions

Whitney Homes can create an attached but enclosed outdoor oasis for parties and other gatherings. We build glassed-in patio enclosures or sun rooms to extend the usable space in your home to a bright, welcoming area perfect for reading or just escaping to watch the rain run down the oversized glass panels. Whitney Homes can use ground up construction to build your exterior addition or remodel your existing structure to create your new getaway.

Granny Units, a.k.a.: Accessory Dwelling Unit (ADU)

Also known as ‘Granny Units’ or ‘Mother-In-Law Units’, these structures are detached from the main house and serve as a separate dwelling. They usually have bathrooms, bedrooms and full heating and cooling systems with plumbing and electrical wiring that is typically separate from the main dwelling. One major advantage to adding an ADU is that it can serve as an investment since it can potentially generate rental income.

Garage Additions

Many older homes in Sonoma County were built with small, one car garages or without garages entirely. This forces you to park in your driveway or worse, on the street where your car is exposed to potential theft or damage.

Whitney Homes builds spectacular garage solutions that will house your valuable automobile and keep it safe and clean. A garage addition creates more storage space for your other valuables as well.

Bedroom Addtions

Adding extra space to your home is one of the most common reasons for a Sonoma County house remodel. Adding living space to your bedrooms allows you to make room for a new baby or another family member, giving you breathing space where you need it. Adding extra space to your bedrooms is also an excellent way to increase your home’s real estate value.

Bathroom Additions

Reasons for adding a bathroom to your existing home are varied and compelling. One major reason is that adding a bathroom will significantly increase your property value. Next to kitchen remodels, bathroom additions offer one of the most significant returns on your investment in construction costs.

Other reasons could include: better accommodations for your guests, changing the bathroom style or layout, adding storage solutions and of course, repairing water leaks or other damage.

Commercial Projects

We don’t just do residential properties, we do commercial projects as well.
