Your backyard,
reimagined.

A basic paver patio runs $8–$18 per square foot installed, depending on material and base prep. A mid-range covered patio with pavers, a pergola, and lighting typically comes in at $25,000–$55,000. A full outdoor kitchen with gas, electrical, built-in grill, fire feature, and covered structure can range from $45,000–$100,000+. Cosmo provides a detailed written estimate before any commitment.

It depends on the city and the structure. Freestanding shade sails and simple open lattice under a certain square footage often don't require a permit. Attached covered patios, solid-roof ramadas, any structure with electrical or gas, and retaining walls over 30" typically do. We know the rules for every East Valley city and pull all required permits as part of our process.

Travertine is the most popular choice in the East Valley — it stays cooler underfoot than concrete or dark pavers, drains well, and holds up to freeze-thaw cycles in higher elevations. Concrete pavers and porcelain are also excellent. We avoid materials that absorb heat or become slippery when wet, and we always spec a proper compacted base with drainage to prevent settling during monsoon season.

A standard paver patio or pergola typically runs 2–4 weeks from start to finish. An outdoor kitchen or full backyard transformation with multiple elements — covered structure, gas fire feature, built-in kitchen — usually takes 6–10 weeks. We give you a project timeline in writing before work begins.
