Make More Room for the Life You Want at Home

Your home can be exactly where you want to stay and still leave you wishing for more room. A larger kitchen. A first-floor primary suite. More bedrooms upstairs. Space for family to stay close. Brookside Brothers designs and builds custom home additions in Lancaster, PA, around what your existing house is missing and what you want the new space to make possible.

What Would More Room Let You Do?

The right addition starts with what your home needs to do that it can’t comfortably do today. That could mean opening up the first floor, adding private space for family, building upward, or finally giving cars, hobbies, and everyday routines enough room.

  • Expand Your Kitchen & Living Space

    Give cooking, dining, and everyday living the space they actually need. An addition can expand a tight kitchen, create space for a larger island or dining area, or give you the family room your current floor plan simply can’t fit.

  • Add a Primary Suite

    Create a bedroom that provides more than a place to sleep. Add a private bathroom, better storage, or a first-floor suite that can make everyday life easier now and in the years ahead.

  • Build a Second Story

    Gain substantial living space without giving up your yard. A second-story addition makes room for bedrooms, bathrooms, an office, or other spaces your existing floor plan doesn’t have.

  • Create In-Law Quarters

    Bring a parent or loved one closer while giving everyone room of their own. A custom in-law addition can provide the privacy, comfort, and everyday spaces that make multigenerational living possible.

  • Add or Expand a Garage

    Make room for more than the cars. A new or expanded garage can add valuable space for vehicles, storage, tools, hobbies, outdoor gear, or the things that currently compete for room elsewhere.

  • Add a Sunroom or Enclosed Living Space

    Add a bright, enclosed porch or sunroom that keeps you connected to the outdoors through more of Pennsylvania’s changing seasons. Use it for morning coffee, plants, reading, entertaining, or simply enjoying the backyard when the weather keeps you inside.

Addition and Full Home Remodel

Make the Addition Feel Like It Belongs

A custom addition should look like it was always part of your home. Brookside brings more than 25 years of local remodeling experience, along with a second-generation master carpenter, skilled craftsmen, and design experts who understand how to connect new construction with homes of every age and style.

That experience guides details like:

  • Rooflines, pitches, and proportions
  • Windows and door placement
  • Siding and exterior materials
  • Flooring, trim, and finishes
  • Transitions between old and new
  • Original architectural details worth preserving

From newer homes to historic architecture, Brookside designs each addition to respect what’s already there while making the new space feel intentional and complete.

Start With the House You Already Have

A custom addition starts with understanding how your existing home works and where new space can improve it. Brookside considers the house and property together before determining what and where to build.

That includes:

  • Your current floor plan and layout
  • Connections between old and new spaces
  • Available space on your property
  • Whether to build out or up
  • Existing structure, plumbing, HVAC, and electrical
  • Rooflines, windows, and exterior materials
  • Effects on adjoining rooms and spaces

Your Addition Stays in Brookside Hands

Brookside doesn’t hand your addition off to subcontractors. Your project is built by Brookside’s own skilled craftsmen, giving you one experienced team responsible for the work from start to finish.

Brookside also works with trusted local suppliers for premium building materials, fixtures, and finishes. When it’s time to make interior selections, you can visit partner showrooms to see and compare materials in person before deciding what belongs in your home.

Know What’s Happening With Your Home Addition

Brookside manages the project, but you’re never shut out of it. You’ll know what’s planned, what’s happening next, and when a decision needs your attention.

Planning a Home Addition?

Start With These Questions

  • Is it better to build out or add a second story?

    It depends on your home, lot, and goals. Building out can simplify access to existing living spaces, while building up preserves more of your yard.

  • How do you make a home addition match the existing house?

    Brookside considers rooflines, proportions, windows, materials, trim, and interior transitions. With experience ranging from newer homes to historic architecture, our team designs additions to look like they belong.

  • Does Brookside Brothers design custom home additions?

    Yes. Brookside designs each addition around your existing home, property, needs, and budget, then builds it with our own skilled craftsmen.

  • Do I need a permit for a home addition in Lancaster or Lebanon County?

    Yes, home additions generally require permits. Zoning, setbacks, and other requirements vary by municipality and property, so they need to be considered during planning.

  • Can I stay home while my addition is being built?

    Often, yes, but it depends on the project and which parts of your home are affected. Brookside provides a detailed schedule and Buildertrend access so you know what’s happening and can plan around the work.
