Pergola & Deck Builder in Ken Caryl & Columbine.
Deck Giant is based in Littleton, a few minutes from both. We design and build custom cedar and pine pergolas and custom decks for homes in Ken-Caryl Ranch, Columbine, and the neighborhoods around them.
Both areas have Littleton mailing addresses but sit almost entirely in unincorporated Jefferson County, so permits and the new county wildfire code apply here, not City of Littleton rules. We handle the permit and help you through HOA approval.
DECK + PERGOLA COMBO
Getting a Pergola or Deck Approved in Ken-Caryl Ranch
Every home in Ken-Caryl Ranch falls under the Master Association, and its Architectural Committee has to approve exterior projects before any work starts. That includes pergolas, patio covers, decks, privacy screens, and hot tubs. It is a separate step from the county building permit, and it is the one that most often sets the schedule.
What the committee looks for
A pergola or patio cover has to fit the color and architectural style of the house. In practice that usually means a stain that works with your trim or siding rather than a raw or mismatched finish. Privacy screens are capped at 6 feet above original grade unless the committee approves more, which matters when we design a privacy wall.
What goes in the request
For a pergola: a photo or rendering, a site plan, dimensions, materials and colors, and the roof style and pitch. A deck also needs a grading plan showing setbacks, floor plans, and elevations. We provide the drawings, dimensions, and material and stain details for your submittal, and can add a 3D rendering if you want one.
How long it takes
The committee reviews requests twice a month. Most decisions come back within two weeks, and bigger projects can take up to 30 days. Some neighborhoods also have a subassociation that has to sign off. We plan the build date around that window so nobody is waiting on a crew.
Backing up to open space? Crews cannot cross Ken-Caryl open space to reach your yard without a separate access permit, which can take up to 30 days. We check access during the site visit. Association rules change from time to time, so we confirm the current guidelines before every submittal.
Valley Slopes, Plains Patios & Columbine Decks
Three different kinds of backyard within a few miles of each other.
The Valley: sloped lots and elevated decks
Homes in the Ken-Caryl Valley sit between the hogback ridges, and many lots slope away from the house. That often means a walkout level and a second-story deck with tall posts and stairs down to the yard. Footing depth, post bracing, and how the deck ties into the house all matter more on a slope. Building on hillsides is our specialty. See how we price a steep-lot deck, line by line.
The Plains: flat yards and patio pergolas
East of C-470, yards are flatter and the usual project is shade over an existing patio. A cedar pergola attached to the house, or freestanding over a concrete or paver patio, goes up in a couple of days once approvals are in. Add a polycarbonate roof and the patio works in rain, not just sun.
Columbine: replacing the original deck
Much of Columbine was built in the 1970s and '80s, and plenty of backyard decks are original or close to it. When we look at an older deck, we check the framing, footings, and the connection to the house, not just the boards on top. New decking over tired framing is money spent twice. If the structure is sound, resurfacing can make sense. If not, a rebuild to current code is the safer call. HOA rules vary a lot from one Columbine neighborhood to the next, so we check yours early. Columbine Valley, the small town next door, is its own municipality with its own building rules.

Jefferson County's Wildfire Code and Your Deck
Starting with permits applied for on or after July 1, 2026, unincorporated Jefferson County enforces a new Wildfire Resiliency Code. It applies to properties inside the county's Wildland-Urban Interface (WUI), the mapped zone where homes meet grass, brush, or forest that can carry a fire. The county expanded that map this year, and it now reaches out into the plains, so it can cover homes that never had wildfire rules before.
Deck surfaces and framing are among the items the code covers, and it bans storing firewood or other combustibles under a deck attached to the house. Only the part you are building has to meet the code, so a new deck does not force changes to the rest of the home. Requirements are stricter in higher-risk areas than lower-risk ones, and the homeowner signs a county form confirming the work complies.
What this means for you: whether your parcel is in the WUI can change which decking and framing materials make sense, and what they cost. We look up your address on the county map before we price anything, so the quote you get already reflects the rules for your lot.
What It Costs in Ken Caryl & Columbine
Our pricing is the same across the metro and published up front. Pergolas start at $32 per square foot for cedar and $30 for pressure-treated pine, measured on the roof footprint. As a starting point, a 12-by-16-foot cedar pergola runs about $6,100 before roofing, stain, or walls.
Decks start at $45 per square foot for composite or cedar, $40 for pressure-treated pine, and $60 for exotic hardwood. Elevated decks on Valley slopes cost more because of the taller posts, deeper footings, and stairs, and we price those after seeing the site.
Popular add-ons: polycarbonate roofing at $16 per square foot, cedar privacy walls from $18, and stain from $7. Build a deck and pergola together as one project and you save 10% on the total.
