Patio Building
Custom wood and composite decks for flat lots and hillside properties — designed and built by Ryan, the owner, from footings to finish.
Decks that earn their space
A deck extends your home outward. It turns the space between your back door and your yard into somewhere you actually want to be — breakfast, sunsets, Saturday morning coffee.
But a deck has to earn that space. The framing has to handle the load. The footings have to reach stable soil. The materials have to survive sun, rain, and years of foot traffic.
Ryan builds decks that last because he builds them himself — from digging footings to driving the last screw. No crew, no subcontractors. Just the owner, on your property every day.
Deck types we build
Ground-level decks
The simplest and most affordable option. Ground-level decks sit close to grade and provide a flat, clean surface for outdoor living. Ideal for relatively flat yards where you want the warmth of wood or composite instead of concrete.
Ryan frames ground-level decks on adjustable deck blocks or shallow footings depending on soil conditions. Every frame is pressure-treated and built to the same structural standard as an elevated deck.
Elevated decks
For homes where the back door is above grade level — common in Altadena where many homes sit on raised foundations or hillside lots. Elevated decks require deeper footings, engineered posts, beams, and properly attached ledger boards.
Ryan builds elevated decks with the structural integrity LA County inspectors expect — proper flashing at the ledger, Simpson Strong-Tie hardware at every connection, and posts on concrete piers reaching stable soil.
Hillside decks
Altadena’s most challenging — and most rewarding — deck builds. Hillside properties often have dramatic views but no flat space to enjoy them. A hillside deck creates that space, cantilevered or supported by tall posts anchored to deep footings.
These decks require engineering. Ryan works with structural engineers to design framing systems that handle the loads, the slope, and Southern California’s seismic requirements.
Multi-level decks
For properties where a single flat deck doesn’t fit the terrain. Multi-level decks step down a slope or create distinct zones — dining, lounging, and ground-level landing. Each level is independently framed and connected with stairs built to code.
Materials
Pressure-treated lumber
The most affordable decking material. Modern pressure-treated pine resists rot and insects, takes stain well, and lasts 15-20 years with regular maintenance. Best for budget-conscious projects or decks that will be painted or stained.
Cedar and redwood
Natural beauty and inherent rot resistance. Cedar is lighter in color with a clean grain; redwood is richer and denser. Both need regular sealing. Ryan sources quality-grade lumber — not the warped, split boards from big box stores.
Composite decking
Composite boards don’t splinter, rot, or need staining. Brands like Trex, TimberTech, and Fiberon offer 25-year warranties. Composite costs 40-60% more than pressure-treated upfront, but the total cost of ownership is lower with zero maintenance. Ryan installs composite with hidden fasteners for a clean, screw-free surface.
What makes a deck last
Footings that reach stable soil
Ryan digs footings to code depth — typically 18-24 inches in Altadena. Each footing is poured concrete with a post base that keeps wood above the concrete to prevent wicking.
Proper ledger attachment
The ledger board is the most critical connection — and the number one cause of deck collapses nationwide. Ryan lags the ledger into the house’s rim joist or concrete foundation, installs flashing to prevent water intrusion, and seals every penetration.
Structural framing
Joists, beams, and posts are sized for the span and the load. Every joist hanger, post cap, and beam connector is Simpson hardware, properly fastened.
Ventilation
Decking boards need airflow underneath to dry after rain. Ryan spaces boards with consistent gaps and ensures adequate clearance between frame and ground. Trapped moisture rots framing — even pressure-treated framing.
Building on Altadena terrain
Altadena isn’t flat. Deck builds here often involve:
- Slope analysis to determine footing depths and post heights
- Soil evaluation — decomposed granite drains well but may require deeper footings
- Access planning — getting lumber and concrete to hillside sites takes creative logistics
- View optimization — positioning the deck to capture mountain or city views
Ryan has built decks on the flats, moderate slopes, and steep hillsides throughout the San Gabriel Valley. He knows the terrain and designs for it.
Permits and inspections
Most decks in LA County require a building permit. Ryan handles the entire permit process — plan submission, revision coordination, and scheduling inspections. The deck passes because it’s built to code from the start, not because it got lucky at inspection.

Pricing guidance
Deck construction in Altadena typically costs $30–$60 per square foot for pressure-treated wood and $45–$85 for composite. A standard 200-square-foot deck runs $6,000–$17,000 depending on material, height, and complexity. Elevated hillside decks cost more due to structural requirements.
