Custom Home Builder in Mt. Lebanon, PA

Building Your Dream Home in Mt. Lebanon with Costa Homebuilders

Mt. Lebanon is four to six miles south of downtown, connected by the Liberty Tunnel, home to the top-ranked high school in the Pittsburgh metro area, and one of the most consistently desirable addresses in Allegheny County for over a century. People who live here tend to stay for a long time. And when they’re ready to build new, the question isn’t whether to leave. It’s how to build a home worthy of the community they’ve already chosen. That’s where Costa Homebuilders comes in. The New Life® Process starts here.

What Sets Costa Homebuilders Apart in Mt. Lebanon?

Mt. Lebanon buyers have options, and they know it. What they don’t always have is a builder willing to start from scratch, based on how a specific household lives, rather than presenting a gallery of pre-drawn plans and calling it custom. Costa Homebuilders has earned 8 Best of Houzz awards and the 2024 BAMP Housing Award for Best Single Family Detached Home over $2 million.

Costa builds ranch homes, one and a half story designs, and two story custom homes. Every style starts as a blank page and gets designed around your lot, your lifestyle, and how your household actually uses space.

What makes the difference is The New Life® Process, Costa’s step-by-step building system that keeps clients informed and on schedule from the first design conversation through final walkthrough. Every home starts with a dedicated architect who learns how you live before a single line gets drawn.

Here is What That Looks Like in Practice:

A dedicated architect for your specific build

Every home begins with a real architectural collaboration. We learn how you live, what you need, and how the home needs to function before design begins. In Mt. Lebanon, where lot sizes and existing neighborhood character vary considerably across subdivisions, that level of site-specific planning isn’t optional.

A Process Built to Reduce Friction

The New Life® Process guides every step of the build. Timelines stay transparent, clients stay informed, and expectations stay aligned from first meeting through final walkthrough. Building custom in an established community like Mt. Lebanon involves real complexity. The process handles it.

Craftsmanship With a Long Record

Costa has built luxury homes in the Pittsburgh area since 1998.

Customization Options for Your Mt. Lebanon Home

Mt. Lebanon has a distinct architectural character built over a century of development, and buyers here tend to have strong opinions about what they want. These are the features that come up most consistently when we work with clients building new in this community.

Open Concept Kitchen and Living Design

Mt. Lebanon's older housing stock was built for a different era of living. Walls between kitchens, dining rooms, and living areas made sense in 1940. They don't reflect how most households actually live today. When you're building new with Costa, the floor plan starts with how your family uses space rather than how someone else's family did decades ago. Oversized islands, connected living areas, and a layout designed for the way you actually entertain are all on the table from day one.

Home Offices

A spare bedroom with a desk isn't a home office. Mt. Lebanon attracts professionals who work at a high level and need a dedicated workspace that reflects that. Proper acoustic separation, built in storage and shelving, dedicated lighting, and a room designed to function as a genuine professional environment are design decisions that belong in the architectural conversation early, not as an afterthought during selections.

Outdoor Living That Fits the Neighborhood

Mt. Lebanon's tree lined streets and mature landscaping create a natural backdrop for outdoor living spaces that feel like an extension of the home rather than an addition. Elevated decks, covered patios, outdoor kitchens, and thoughtful landscaping that complements the neighborhood's established character are all features worth designing carefully when you're building new on a South Hills lot.

Primary Suites Designed as Retreats

Mt. Lebanon buyers building new aren't settling for a standard primary suite. Spa-caliber bathrooms, custom closet systems, sitting areas, and thoughtful separation from the rest of the home's activity are all features that make a real difference in how a home lives day to day. When you're building from scratch, these decisions cost far less than retrofitting them into an existing home.

Living the Mt. Lebanon Lifestyle

If you are looking to build a custom home in Mt. Lebanon, here are some of the activities you will get to enjoy.

Uptown Mt. Lebanon

The central business district with local landmarks like Rollier’s Hardware, Grandpa Joe’s Candy Shop, and specialty boutiques running along a genuinely walkable corridor. The Uptown Market runs Saturdays from May through October. Bistro 19 anchors the upscale dining end with refined American fare in an elegant setting.

Beverly Road District

A smaller, neighborhood-scale commercial strip with local favorites including Mediterra Cafe and Scoops on Beverly. The kind of walkable block that makes a community feel like it has real texture rather than just retail square footage.

The Galleria

An upscale indoor mall minutes from most Mt. Lebanon neighborhoods with higher-end retail, The Yard gastropub, and an AMC theater. Practical and polished in equal measure.

Mt. Lebanon Park

A 100-acre municipal park with a swim center, an ice center for public skating, and Martha’s Playground, a recently renovated family facility. One of the better municipal park systems in the South Hills, used year-round by residents of all ages.

Bird Park

A wooded escape within the suburban landscape, popular for nature trails and birdwatching. Quiet, well-maintained, and a genuine counterpoint to the busier parts of the community.

Hitchhiker Brewing Co. and Local Dining

Hitchhiker is one of Pittsburgh’s most respected craft breweries with a Mt. Lebanon location. Totopo for Mexican, Little Tokyo for sushi, and Pamela’s Diner for weekend breakfast round out a dining scene that punches well above the typical suburban average.
