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 will give you plenty of inspiration for your 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 their 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 set your brick 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 display in our sidewalks, patios, fireplaces, etc.

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

Stop by and visit:

• Check out our 6 acres of showroom and inventory made up of real paver and wall installations.

• Get some ideas for that paving stone or retaining wall project you've been waiting to start and let us help you with your design.

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

• Get a contractor recommendation if you'd rather not do it yourself.

Whatever your need, we can help!
