Outdoor spaces built for Pacific Northwest weather.

Portland's outdoor season is short and the weather is finicky. The outdoor spaces that actually get used are the ones built to work in our climate: covered, drained, well-lit, and finished with materials that survive a wet winter.

Designed for October, not just for July.

The single biggest reason an outdoor living project disappoints isn't workmanship. It's that it was designed for July and built for July without thinking about October through April. We start with how you actually want to use the space across the year, and design backwards from that.

Covered decks, patios with real drainage, outdoor kitchens with proper gas and electrical, fire pits with structural footings, lighting designed at the same time as the structure. One crew through the whole build.

What we design and build outside

  • Covered decks and patios. Roofed structures that extend usable outdoor time from May-October to nearly year-round. Engineered for Portland snow and rain loads
  • Open decks. Cedar, composite (Trex, TimberTech, Fiberon), or PVC on engineered framing with code-compliant railings
  • Patios. Stamped concrete, exposed aggregate, paver, or natural stone, properly graded and drained
  • Pergolas and shade structures. Cedar, fir, or steel-framed, standalone or attached
  • Outdoor kitchens. Built-in grills, refrigeration, sinks, counters, storage. We coordinate gas, electrical, plumbing, drainage
  • Fire pits and outdoor fireplaces. Gas, wood, or hybrid, with structural footings and proper line routing
  • Outdoor lighting. Low-voltage path, deck and stair lighting integrated into the structure, sconce work, overhead pendants for covered spaces

The questions we ask early

  • Do you want to use this in the wet months? If yes, a roof or substantial cover is non-negotiable. Pergolas alone don't cut it
  • Where does the water go? Decks and patios need real drainage. Roofed decks need gutters that tie to the existing system or to daylight, not just dump on the lawn
  • What's the sun exposure? South-facing decks in summer get punishing. North-facing covered spaces in winter stay cold and damp. We plan accordingly
  • Heating strategy. Overhead infrared, gas heaters, an outdoor fireplace, or a fire pit can extend usable months by 4 to 6 if planned right
  • Lighting strategy. Portland evenings are long and dark much of the year. Designing lighting at the same time as the structure is dramatically cheaper than retrofitting

How a Keyser outdoor project runs

Consultation, permits, build. Most outdoor work builds best in our drier May to September window.

01

Yard walk & concept

We walk the yard with you, talk through how you want to use the space, and look at sun, drainage, grade, and how the project will tie into the existing house. Free, no obligation.

02

Design, estimate, permit

Sketches, materials direction, and a realistic budget within a week. Line-item estimate with materials specified. Decks above a certain height, attached covered structures, and most outdoor kitchens need permits. We pull them.

03

Build, inspect, walkthrough

Footings, framing, decking, finishes, gas and electrical for outdoor kitchens, lighting. Same crew through to completion. Final walkthrough at close-out.

Ready for an outdoor space you'll actually use?

Tell us what you want to build and where in the yard. We come out, walk it with you, and follow up with concept direction and a budget conversation within a week.

Materials we recommend for our climate

  • Decking: Western Red Cedar for natural wood. Composite (Trex, TimberTech) or PVC (AZEK) for low-maintenance
  • Framing: pressure-treated for ground-contact, often with hidden flashing and joist tape to extend life
  • Hardware: stainless or hot-dipped galvanized only. Standard zinc-plated fails fast in wet conditions
  • Roofing on covered decks: matched to existing home roof when possible, or polycarbonate if you want to keep light coming through
  • Stone and masonry: materials that handle freeze/thaw without spalling. Some otherwise-attractive natural stone is a bad choice for Portland

Typical Portland-area outdoor pricing

Mid-2020s market. Cover is the smartest dollar: a covered structure gets used roughly 4x more days per year than the same square footage open to the sky.

$8K+
Pergola (freestanding or attached, cedar)
$20K+
Mid-size open deck (300-500 sq ft, composite)
$40K+
Covered deck (300-500 sq ft, full roof)
$35K+
Outdoor kitchen (full build, covered)

Outdoor living FAQs

How long does an outdoor project take?
Open decks and patios typically run 3 to 6 weeks of on-site work. Covered structures and outdoor kitchens generally run 6 to 12 weeks once permitted. Permit time ranges from a few days for a simple deck to 6 to 10 weeks for anything attached to the house.
What's the smartest dollar to spend on an outdoor project?
Cover. A covered deck or patio gets used roughly 4x more days per year than the same square footage open to the sky. If you're choosing between a bigger open deck or a smaller covered one for the same budget, smaller and covered usually wins.
Composite versus real wood for decking?
Composite (Trex, TimberTech) and PVC (AZEK) are lower maintenance and hold up well in Portland's wet climate. Cedar is more beautiful and ages with character if you keep up with sealing every 2 to 3 years. For most clients with busy schedules, we recommend composite. For clients who love the look of natural wood and don't mind upkeep, cedar.
Can you tie this into our existing roof?
Often yes, but it has to be engineered. Improperly attached covered structures cause roof leaks and structural problems down the line. We engineer the tie-in correctly the first time.
Do we need permits?
Decks more than 30 inches off the ground require permits and code-compliant guardrails. Covered structures attached to the house need engineered connections. Gas line work requires a licensed plumber and inspection, same with significant electrical for outdoor kitchens. We pull what's needed.
How do we get started?
Send us a note or call (503) 997-5895. We'll come out, walk the yard, and follow up with concept direction and a budget conversation within a week.
