Add Space That Fits Your Home

Custom home addition design and construction in the greater Harrisburg area for homeowners who need more room without moving.

When your home no longer has enough space for your family, you have two choices: move or build. Adding square footage to your existing home lets you stay in the neighborhood you know while creating the rooms you need. Dickerson Basements & More designs and builds home additions that match your existing structure in style, materials, and roofline so the new space looks like it was always there. Whether you need a sunroom with natural light, an in-law suite with its own entrance, a larger living area for gatherings, or a second-story addition over your garage, the work is planned around your property's setbacks, zoning rules, and how you use your home.


This service includes design consultation, permitting through local municipalities in Central Pennsylvania, foundation or structural work to support the new space, framing and roofing that ties into your existing home, and interior finishes that match your style. Every addition is built to handle regional weather, including winter snow loads and seasonal temperature swings. The result is functional space that increases resale value while meeting your family's needs now.

How the New Space Connects to What You Already Have

The goal is to make the addition feel like part of the original home, not an afterthought. In the greater Harrisburg area, this means matching siding, roofing materials, and window styles, then tying the new foundation into the existing structure with proper footings and drainage. Framing is built to code, insulation meets or exceeds current standards, and interior finishes are selected to flow with the rest of the house.


Once the work is complete, you will walk through doorways that feel intentional, use rooms with consistent flooring and trim, and enjoy climate control that works as well in the new space as it does in the old. The addition will have its own electrical circuits, proper ventilation, and windows positioned for light and airflow. If the project includes plumbing, you will have new fixtures that tie into your home's existing lines without causing pressure or drainage issues.


This type of construction is ideal for growing families or homeowners planning for multi-generational living. It also works well when you need a dedicated space that is separate from the main living areas but still connected. Zoning and setback requirements vary across Central Pennsylvania municipalities, and every project is planned with those restrictions in mind from the start.
