Landscape Design Firms vs
Garden Design Specialists

A landscape design firm focuses on the structural and engineering elements of your outdoor space — hardscape, grading, drainage, outdoor structures, irrigation, and lighting. They handle the "bones" of your yard. A garden design specialist focuses on the horticultural and ornamental elements — plant selection, flower beds, seasonal color, pruning, and botanical detail. They handle the "softscape" and living elements. The best outdoor spaces require both skill sets. Many landscape firms subcontract planting to gardeners, and many garden designers do not handle hardscape at all. P&L Outdoor Solutions integrates both disciplines under one contract so your hardscape and planting design are created as one cohesive plan.

Start with a landscape design firm if your project includes any hardscape, grading, drainage, or structures. The hardscape must be designed and installed before planting beds are laid out — you cannot properly position a garden bed until you know where the patio edges, retaining walls, and drainage channels will be. If your project is exclusively planting-based with no structural work, a garden designer is the right first call. For most homeowners in Northern Virginia who want a complete backyard transformation, the landscape firm should lead because they coordinate the structural elements that define where everything else goes.

Generally no. Garden designers specialize in horticulture and typically do not carry the contractor licenses, liability insurance, or structural engineering knowledge required for patios, retaining walls, decks, or outdoor kitchens. In Virginia, any hardscape project over $1,000 requires a DPOR contractor license. Attempting hardscape without proper licensing exposes homeowners to liability if workers are injured and voids warranty protections. If a garden designer offers hardscape services, verify they hold a valid Class A, B, or C contractor license (RBC or CBC classification) and carry general liability plus workers compensation insurance.

On large estate projects, the typical workflow is: landscape firm designs and builds hardscape, drainage, and structures first; garden designer then creates planting plans that work within the completed hardscape framework; and garden designer or landscape maintenance crew handles ongoing seasonal care. The risk in this model is miscommunication between the two teams — a patio built without considering root zones can damage mature plantings, and a garden bed designed without considering drainage can flood. At P&L, we eliminate this risk by handling both disciplines in-house with one project manager overseeing the entire design.

P&L Outdoor Solutions is a landscape firm with deep horticultural expertise — the best of both worlds. We handle hardscape engineering, drainage, permits, and structural installation (the landscape firm role) while also designing native plant palettes, seasonal succession plans, and soil health programs (the garden specialist role). The result is a unified outdoor space where every hardscape element is designed with planting integration in mind, and every planting plan respects the structural and drainage realities of the site. One contract. One project manager. One warranty covering everything.

Landscape design firms in Northern Virginia typically charge for hardscape projects ranging from $8,000–$80,000+ depending on scope. Garden designers charge for planting design and installation ranging from $2,000–$15,000 depending on bed size and plant selection. Ongoing garden maintenance ranges from $200–$800 per month. When you hire separate firms, you pay full price for both. P&L's bundled approach typically saves 15–25% because the same crew handles both hardscape and planting under one timeline, and the design is created as a whole rather than retrofitting plants onto completed structures.
