Hardscaping Design, & Build

Delaware & Pennsylvania

At Irwin Landscaping, every hardscaping project begins with a conversation. We take the time to understand how you live, how you want to use your outdoor space, and the architectural character of your property before developing a custom design.

Through a highly collaborative design-build process, we guide you through layout, materials, structural considerations, and construction. From patios, walkways, retaining walls, outdoor kitchens, and fire features to pools and complete outdoor living environments, we create high-end hardscapes that feel personal, intentional, and seamlessly connected to your home.

What types of hardscaping projects do you design and install?

Irwin Landscaping designs and installs custom patios, walkways, steps, retaining walls, garden walls, outdoor living areas, paver surfaces, and other hardscape features. Each project is designed around the architecture of the home, the grade of the property, drainage, access, and how the homeowner wants to use the outdoor space.

How do you choose the right materials for a patio or walkway?

Material selection depends on the style of the home, intended use, surrounding landscape, maintenance preferences, drainage needs, and any HOA or township requirements. We help homeowners select pavers, stone, colors, patterns, and finishes that complement the property and perform well over time.

Can hardscaping help with slopes and difficult grade changes?

Yes. Steps, retaining walls, walkways, terraces, and carefully planned transitions can make steep or uneven properties easier and safer to use. We consider grading and access during the design process so the hardscape feels like a natural part of the property rather than an added feature.

What are permeable pavers and when are they needed?

Permeable pavers are installed over a specially prepared base that allows rainwater to pass through the joints and filter into the ground below. They can be an effective solution when a township limits the amount of impervious surface allowed on a property or when stormwater management is an important part of the project.

Do you consider drainage when designing patios and hardscapes?

Yes. Drainage is an important part of every hardscape design. We evaluate slope, runoff, existing grades, surrounding planting areas, and how water moves across the property before determining the layout and construction approach. Proper drainage helps protect both the hardscape and surrounding landscape.

Do you work with HOAs on hardscape approvals?

Yes. Many HOA communities require approval before patios, walkways, walls, or other exterior improvements can be installed. Irwin Landscaping can design with HOA guidelines in mind and prepare the plans and project information needed for the homeowner’s submission, including materials, colors, dimensions, and proposed locations.

Do you help with township permits and hardscape regulations?

Yes. Depending on the project and municipality, hardscaping may be affected by permits, setbacks, lot coverage limits, stormwater rules, drainage requirements, or restrictions on impervious surfaces. We identify these requirements during the planning process and help determine what approvals are needed before construction begins.

Do you provide hardscape design and installation in Delaware and Pennsylvania?

Yes. Irwin Landscaping provides professional hardscape design and installation throughout our service areas in Delaware and Pennsylvania, including patios, walkways, steps, retaining walls, permeable paver systems, and complete outdoor living spaces.
