Pergolas & Outdoor Structures

Defining Your Outdoor Space

A flat patio is functional. A patio with a heavy timber pergola has gravity. It gives the space vertical definition, filters the harsh summer sun, and turns a simple sitting area into a true outdoor room. We build serious outdoor structures in Edwardsville, Glen Carbon, and the surrounding Metro East communities. We do not construct snap together kits. We build from scratch using heavy timber beams, solid masonry columns, and industrial grade hardware.

When we design a pergola into your landscape plan, we evaluate exactly how you plan to use the space. Whether it is a freestanding structure out by the pool or a custom attached design covering your outdoor kitchen, the build process demands precision. The footings have to be dug deep and poured right. The columns need a solid foundation so they do not settle. The rafters must be sized correctly so they do not bow or warp over the years. We take pride in building it right the first time.

We offer both traditional open rafter designs for partial shade and solid pavilion structures for complete rain protection. The wood is carefully selected, treated, and finished to match the style of your home. We hide the hardware where possible and use decorative heavy gauge brackets where they are visible. The result is an architectural feature that looks like it belongs with your home and will stand up to anything the Midwest weather can throw at it.

How We Build Our Structures

  • Proper Footings: Every column starts with deep concrete footings excavated below the frost line to prevent heaving.
  • Masonry Columns: We wrap our base posts in block and finish them with high quality stone veneer to match your patio or home exterior.
  • Heavy Timber Framing: We use oversized beams and rafters that look substantial and refuse to sag over time.
  • Hardware and Anchoring: We utilize heavy duty post bases, specialized structural screws, and architectural brackets for absolute rigidity.
  • Shade Coverage Planning: We calculate rafter spacing to provide the exact amount of filtered shade you want for the time of day you use the patio most.
  • Integrated Utilities: All wiring for low voltage lighting, outlets, and ceiling fans is routed internally before the structure is finished so you never see exposed conduits.
  • Attached or Freestanding: We design custom ledger attachments to integrate with your home or build massive freestanding structures that stand entirely on their own.

Why JS Lawn

We cater to high end properties where cutting corners is not an option. The materials are heavy and the craftsmanship is exact.

We design and construct both. Attached structures require careful ledger installation and waterproofing to protect your home exterior. Freestanding units require massive footings to prevent wind sway. We execute the build properly for either scenario.
