Add a Room That Brings More of the Outside In

You love your home and backyard. You just wish you could enjoy the connection between them more often. Brookside Brothers designs custom sunrooms and patio enclosures in Lancaster, PA, that give you more ways to enjoy the outdoors without always being out in the weather.



From a breezy screened porch to a comfortable four-season sunroom, we’ll help you create a space that feels like it was always meant to be part of your home.

How Much of the Outdoors Do You Want to Keep?

You don’t need to know whether you want a screened porch, three-season room, or four-season sunroom yet. Start with two simpler questions: How do you want the space to feel, and when do you want to use it?

Screened Porch Three-Season Room Four-Season Sunroom
Feels Like An outdoor room with more protection A comfortable space between indoors and out Another room of your home
Fresh Air Lots of it Open the windows and screens when you want to Open the windows when weather allows
Weather Protection Roof and screens More protection from rain, wind, and changing temperatures Fully enclosed for Pennsylvania weather
Comfort Fans, shade, or heaters can extend your time outside Designed to extend comfortable use through spring and fall Heating and cooling provide year-round comfort
Best Fit You love being outside but could do without the bugs, hot sun, and passing showers. You want more months outside without creating a fully conditioned room. You want a true living space you can enjoy through summer heat and winter cold.

Still not sure? That’s part of the design conversation. Brookside can help you weigh how you’ll use the room, your home and property, comfort expectations, investment, and how connected you want to feel to the outdoors.

Design the Room Around How You Want to Use It

A beautiful sunroom starts with what you want to happen there. Brookside designs around the everyday moments you’re making room for, then brings the details together.

“Probably the best evidence of their great work is that no one has noticed that we added a front porch to our house. It looks like a natural part of the house, not something that was added later.”

— Ken O.

Start With What You Want to Do There

A quiet place to read? A sunny work-from-home spot? A spot to watch the kids play without the bugs? Start there. How you’ll use the room helps Brookside plan its size, layout, furniture space, doors, outlets, and connection to the rest of your home.

Let the Light Work for You

More windows aren’t always the answer. Brookside considers where the sun hits, the views you want to keep, privacy, glare, and summer heat to make natural light an asset throughout the day.

Make It Look Like It Was Always There

Your new space should belong to your home. Brookside coordinates the roofline, proportions, windows, exterior materials, ceilings, trim, and transitions so the addition feels intentional inside and out.

Already Have a Porch, Patio, or Deck?

You may already have the right place for your new space. Brookside can evaluate an existing porch, patio, or deck and determine what makes sense to enclose, adapt, reinforce, rebuild, or redesign.

The goal isn’t to force what’s already there to work. It’s to find the right way to turn an underused outdoor area into a space you’ll enjoy more often.

One Brookside Team From Design Through Construction

Brookside brings more than 25 years of remodeling experience to the entire project, with one team guiding the design, planning, permitting, construction, and finishing details.

You get a space thoughtfully designed for your home and skilled craftspeople who know how to bring it to life.

Common Questions

  • How much does it cost to add a sunroom in Lancaster, PA?

    Cost depends on the room’s size, foundation, windows, materials, climate control, and whether it’s a three- or four-season space. Brookside develops the investment around your home and plans.

  • Can I enclose my existing porch, patio, or deck?

    Possibly. Brookside can evaluate the existing structure to determine whether it makes sense to enclose, reinforce, rebuild, or start fresh.

  • Do I need a permit to build a sunroom or enclose a porch in Lancaster County?

    Usually, requirements vary by municipality and project but may include zoning approval, building permits, plans, and inspections. Brookside can determine what applies and handle the permitting.

  • Can a four-season sunroom be heated and cooled like the rest of my house?

    Yes. Four-season sunrooms can include heating and cooling for year-round comfort. The right system depends on the room and your home’s existing HVAC.

  • How long does it take to design and build a sunroom addition?

    Timelines depend on design, size, permits, materials, site conditions, and the existing structure. Brookside builds the schedule around your project and keeps you updated through Buildertrend.

  • What should I consider before adding a sunroom?

    Start with how and when you want to use it. Then consider sunlight, views, privacy, weather protection, climate control, and how the new room will connect to your home.
