When your home stops meeting your needs

Your house used to fit. Now a new baby is on the way, or aging parents are moving in, or you have spent two years working from the corner of a bedroom. You have looked at what is for sale nearby and realized that moving means leaving a place you like and paying more for space you could add right where you are.

By the time most homeowners call us, they have made peace with needing more room. What they are unsure about is who to trust to build it. You have probably heard the stories about crews that disappear for weeks and additions that never quite match the house they are attached to. That is the part we take off your plate. Josh McMahon runs every project himself, so one person is accountable from the first meeting to the day you move in, and your new space is framed and finished to sit right against what you already have.

Additions for Goochland and Richmond-area homes​

Goochland gives us larger lots and rural parcels to work with, which opens the door to detached ADUs, roomy garage additions, and ground-level suites that would be tight on a city lot. Closer to Richmond, older homes bring tighter sites and existing structures that need careful framing to build onto. Powhatan and Hanover run much like Goochland on lot size, while Chesterfield and the Charlottesville area each come with their own permitting steps and inspection schedules.

How an addition project works

Every addition starts with a planning conversation and a walkthrough of your existing home, where we look at your goals and how the new space needs to tie into what is already there. Once you approve the contract, we put a crew to work and move from framing through finishes. You get a progress update from us every week, so you always know what happened on site and what is coming next. When the work is done, we walk the finished space with you and make sure it is right before you move in.

Why homeowners choose McMahon Custom Homes

For twenty years Josh has been building across central Virginia, and he brings that experience to every addition himself. We are veteran-owned, locally owned, and welcoming to every family. When your project has to blend into a house you already love, that mix of long experience and hands-on ownership is what makes the difference.
