A couple's home in Parker, Colorado, needs a major deck overhaul to take advantage of the incredible views of the Rocky Mountains and downtown Denver. A $290,000 budget allows the Mega Decks crew to design a 920-square-foot wrap-around deck, floor-to-ceiling stone fireplace, outdoor kitchen with granite bar and sliding glass walls.

Colorado Springs homeowners with a half-finished deck call on Garth to complete the job and deliver the deck of their dreams. James leads the build on the 1,800-square foot dream deck that includes a huge four-season room with a skylight, an outdoor kitchen, three fire features, ornamental steel railings and a custom 7-foot wide spiral staircase. To complete the project, Garth will need to cut down three beloved 40-foot pines, which makes the homeowners a bit apprehensive. Will the ultimate deck be worth the sacrifice?

The Mega Decks crew is faced with their most difficult task to date, delivering side-by-side penthouse decks to neighboring couples in a historic Denver, Colorado, high-rise. The only way to get building materials to the rooftop of the 6-story building is with a crane, and the build team scrambles to carve out space amid multiple crane deliveries. In the end, the crew completes $500k Mega Decks complete with indoor/outdoor rooms, top-of-the-line grill stations, an Alaskan cedar hot tub and a 180-square-foot artificial lawn on a penthouse rooftop.

Garth travels to the Lone Star State to build its first mega deck. Following the mantra "Everything's bigger in Texas," Garth unifies a disjointed patio, doubling the floor space and quadrupling the covered living area. The $325,000 deck is finished with fire pits, a swim spa and a mesquite bar top.

A mountain home in Conifer, Colorado, gets a $375K deck with a wall-sized stone fireplace, a hot tub that seats 12 and a grill kitchen. Jason's team is pitted against Mother Nature, however, when an icy road leads to a delivery truck crash.

Garth and his team brave sub-freezing temperatures in Idaho to build a $590k multi-level deck with four distinct living areas. The indoor-outdoor space features a pizza oven, a mezzanine-level bar overlooking the Snake River and an infrared sauna.

A multi-generational Texas family transforms the existing deck of their Estes Park, CO, vacation home into a luxurious Mega Deck. The rustic Colorado mountain-themed masterpiece features a gable roof that's seamlessly tied into the home's existing architecture with a skylight that pours in natural light. Inside, a rustic great room gets natural log siding and a floor-to-ceiling fireplace with custom masonry. The finishing touches include a new bar-and-grill station and a hot tub, adding a total of 1,000 square feet to the original deck.

In Castle Pines, Colorado, the crew has a $350,000 budget for a contemporary-style mega deck with a curved, hand-cut stone fireplace, sleek steel pergola and pizza oven. But building outdoors in winter subjects the crew to dangerous icy conditions, and a simple oversight threatens the pergola build. Additional mega-features on this project include a 70-inch TV, state-of-the-art grill and fire pit finished with Colorado buff flagstone.

A former Mega Decks customer buys a new house and needs a new deck. Can designer Andy and the build crew live up to the client's heightened expectations and deliver a second mega deck that beats the first? Jason leads a $225,000 build that includes a complicated roof on existing architecture, a soaring tongue-and-groove ceiling with a skylight, a floor-to-ceiling fireplace with an articulated mounted TV, a state-of-the-art grilling station, four seating areas, moveable glass walls and a 14-foot fire rail with stone masonry.

Transforming a home's 20-year-old wooden deck with views of Pikes Peak, Colorado, into a $400,000 mega deck requires a complete demo and rebuild, complete with 13-foot-tall stone wood-burning fireplace, sliding glass panels to enclose the living area, gas fire pit, two dining areas and a grill station complete with granite countertops and a kegerator. Plans also include redoing a kids' play deck and a master bedroom deck. The challenge is that the property sits on the side of a cliff, with 40-foot drops off the deck level and no access from the postage stamp-sized backyard. Master builder James resorts to innovative building methods to get the job done, all while battling 60-mph wind gusts, blinding fog and death-defying heights.

A couple and their adult kids want to add a new deck to their D'Arbonne Lake home in Louisiana. The current deck is rotting and offers no protection from the heat or insects, so Garth's Southern plantation-style design includes enclosed rooms with air conditioning as well as two fire features and whirlpool tubs.

The only downside to spending weekends in this custom log cabin in the mountains of Breckenridge, CO, is its scrawny open-air deck that's only useful a few days a year. To help this tiny deck achieve mega status, massive 40-foot-long Western red cedar logs are trucked in from Canada and diamond-studded chainsaws are used alongside heavy machinery to begin the transformation. The finished product will have a three-tier pizza oven with granite serving station, a six-foot gas fire rail with custom masonry and extra tall glass panels to maximize this luxe log cabin's majestic views.

A couple in Black Forest, Colorado, dislikes their home's small, exposed deck that leaves guests crowded in the tiny hearth room. Garth designs a deck that opens up the walls, triples the original deck footprint and adds a floor-to-ceiling fireplace and TV to create the ultimate party space.
