Add More Living Space Without Moving
Room Additions in Chandler for families outgrowing their current floor plan
HETTENBACH CONSTRUCTION builds room additions in Chandler, Indiana that give you the space your household needs without the upheaval of relocating. When your family grows, your work changes, or your routines shift, the walls of your current layout can start to feel fixed in ways that no longer work. A well-built addition extends your home outward in a way that looks like it was always part of the original structure, giving you a bedroom for a new baby, an office that closes off from the rest of the house, or a family room where everyone can gather without tripping over furniture.
Room additions involve tying new construction directly into your existing foundation, framing, and roofline. The work includes pouring a foundation or slab, framing exterior walls, installing windows and doors, running electrical and HVAC into the new space, and matching siding, trim, and roof materials so the addition reads as part of the whole. You choose the size and layout based on what you need most, whether that means one large room or a two-room suite with a closet and bath. The goal is to make the seam between old and new disappear so visitors cannot tell where the original house ends.

Planning and Building for Long-Term Use
Every addition starts with a site review to confirm where the new space can attach, how utilities will extend, and what the roofline transition will require. You work with HETTENBACH CONSTRUCTION to settle on dimensions, window placement, door swings, and how the interior will connect to your existing hallway or living area. The foundation is poured to match your home's existing grade and drainage pattern, and framing goes up using engineered lumber sized to support the roof load and any second-story weight if your home has one.
Once the addition is enclosed, insulated, and finished, you gain a room that holds temperature like the rest of the house, with trim and flooring that match your existing style. The new space feels like it has always been there, and your household can spread out into it immediately. Furniture fits without crowding, doors close for privacy, and the flow between old and new rooms works naturally.
Electrical and HVAC lines are extended from your main panel and ductwork, so the new room heats and cools on the same system. Roofing is tied into your existing ridge or eave, with flashing installed to prevent leaks at the joint. Siding is matched by profile and color, and the addition is built to the same code standards as the rest of your home. Interior finishes, from drywall texture to baseboard profile, are selected to maintain consistency across the whole house.
What to Expect During the Build
Room additions take several weeks depending on size and complexity, and the process involves coordination across multiple trades. Below are answers to questions that come up during planning.
How long does a typical room addition take to complete?
Most single-room additions take four to eight weeks from foundation to final walkthrough, depending on weather, material availability, and whether plumbing or complex HVAC work is involved.
What happens to the exterior wall where the addition connects?
The existing exterior wall is opened after the new structure is enclosed and weathertight, so your home stays protected throughout the build.
How is the new foundation tied to the old one?
A new footing is poured adjacent to your existing foundation and connected with rebar or anchor bolts, ensuring the addition does not settle independently or pull away over time.
Will the addition affect my heating and cooling costs?
Adding square footage increases the area your HVAC system must condition, but proper insulation and correctly sized ductwork keep the impact manageable and the new room comfortable year-round.
Can I use the rest of my home during construction?
Yes, you continue to live in your home while the addition is built, though there will be noise, dust near the connection point, and temporary loss of access to the yard area where crews are working.
