Allgreen's office is located about 20 miles north of Pittsburgh (10 miles south of Butler) on PA Route 8.

Allgreen has Pittsburgh's largest outdoor showroom. We have examples of paving stones and retaining walls on display in a variety of styles and colors. The sidewalks, outdoor kitchens, fireplaces, and gazebos are bound to give you more than one idea for your own backyard.

Bring pictures and dimensions of your project and we'll help you design your dream backyard. Walk around our outdoor showroom to spark your creativity and we'll assist you along the way.

We'll help you do-it-yourself or get a contractor to do the work for you. We have FREE do-it-yourself seminars monthly where we show homeowners how to easily install paving stones and retaining walls. If you'd rather have someone else do your project, we'll recommend a contractor specifically for your design.

The area behind the parking lot contains our large inventory of paver and wall block products. We're equipped to deliver these products directly to your site, and unlike many dealers in this area, we'll be happy to deliver to most locations in western Pennsylvania, and set your material right where you want it.

We're an authorized dealer for Unilock, Techo-Bloc, and Keystone, makers of world-class paving-stone and retaining-wall products that are on outdoor display.

We also carry a large line of Amish-crafted gazebos and storage sheds.

Stop by and visit:

• Check out our showroom of real paver and wall installations.

• Get some ideas for that project you've been wanting to start.

• Attend a seminar to brush up on your do-it-yourself knowledge.

• Let us help you with a design.

• If you need a contractor to do the job for you, we can recommend one.

Whatever your need, we can help!
