Turning a Small, Exposed Deck Into a Covered Outdoor Living Space

The original outdoor space on this home started with a fairly typical second-story wood deck. It provided a place to step outside from the upper level of the home, but it was relatively small, completely exposed to the weather, and offered limited protection from the rain and sun.

The homeowners wanted something much more substantial.

Instead of simply replacing the existing deck, the plan was to completely rethink this portion of the home and create a multi-level outdoor living space that could be used through much more of the year.

The new design called for an expanded second-story deck, a large gabled patio cover extending above the deck, and a finished dry patio underneath using an UnderCover Systems® under-deck ceiling system.

That meant the new structure had to do considerably more than the deck it was replacing.

The framing and foundation would need to support not only the deck itself, but also the substantial patio-cover structure rising above it. At the same time, the area underneath the deck needed to remain open enough to become another usable outdoor living space.

The end goal was to create two distinct outdoor environments: an elevated covered deck above and a protected patio below.

Removing the Existing Deck and Starting With a New Structure

Once the original deck was removed, the scale of the new project became much more apparent.

The replacement structure extended farther into the backyard and required an entirely new structural approach. New footings were installed to support the expanded deck as well as the load of the patio cover above.

Large vertical posts were set from the foundation level and extended well above the finished deck elevation. These posts became part of the structural backbone for both the deck and the new patio cover.

Because the design combines multiple outdoor living systems into one structure, the framing had to be planned from the beginning around the finished deck, roof structure, railing, drainage system, electrical components, and ceiling below.

Building the Elevated Deck

The new second-story deck was framed using heavy-duty pressure-treated lumber and galvanized structural hardware designed for long-term exterior exposure.

Portions of the project required long structural spans, so the framing included substantial beams and closely spaced joists to create a strong, rigid platform.

Once the framing was complete, the deck was sheathed and prepared for the finished decking system.

The photos from this stage show just how different the new structure was from the original deck. What had previously been a modest platform was now becoming a much larger outdoor room connected directly to the upper level of the home.

Building the Gabled Patio Cover

The defining feature of the project is the new patio cover rising above the second-story deck.

Rather than installing a simple shed-style roof, the homeowners chose a gabled patio cover. The peaked roof gives the space significantly more height and volume while creating an architectural feature that feels intentional alongside the existing home.

Large structural posts extend upward from the deck structure to support the roof beams. From there, the crew framed the gable with rafters spanning across the new outdoor space.

This approach creates a tall, open ceiling over the deck rather than making the area feel enclosed or compressed.

From the backyard, the new roof structure dramatically changes the appearance of the home. The patio cover becomes a substantial architectural extension while still leaving the lower patio open underneath.

Integrating the Patio Cover With the Existing Home

One of the most important parts of a second-story patio cover is properly integrating the new roof structure with the existing house.

The framing had to be carefully positioned around the home's existing windows, doors, siding, and rooflines while creating secure structural connections and maintaining proper weather protection.

As the roof framing progressed, the crew built the new cover directly against the rear elevation of the home and prepared the structure for roofing, flashing, electrical components, and finished ceiling details.

Because this is a permanent roof structure rather than a lightweight seasonal cover, every part of the build had to work together structurally and visually.

Preparing the Deck for TimberTech

With the primary structure in place, the upper deck was prepared for its finished surface using TimberTech® Legacy Collection composite decking.

The Legacy Collection provides the appearance of hand-scraped hardwood with the lower-maintenance performance of capped composite decking.

Matching TimberTech fascia was also incorporated around the exposed edges of the deck to give the finished structure a cleaner appearance from both the upper deck and the backyard below.

Planning for the Finished Patio Below

Even while the deck and patio cover were being constructed above, the team was planning for another important part of the project underneath.

The space below the deck was designed to become a finished covered patio using the UnderCover Systems ClearSpan® Under Deck Ceiling System.

The system captures rainwater that passes through the deck above and directs it into an integrated gutter and downspout system, allowing the patio underneath to remain dry.

Because the finished ceiling would conceal much of the structural framing, electrical wiring, lighting locations, ceiling-fan support, heater connections, and structural swing-hook locations all had to be considered before the ceiling panels were installed.

Building the Project as One Complete System

This project is a good example of why large outdoor living builds need to be planned as one integrated structure.

The deck could not be designed independently from the patio cover, and the patio cover could not be built without considering the foundation and framing below it. Likewise, the UnderCover ceiling, lighting, heating, railing, drainage, and electrical systems all depended on decisions being made earlier in the construction process.

By coordinating those pieces from the beginning, the finished project could ultimately provide a covered deck above and a dry outdoor living space below without either area feeling like an afterthought.

Three Outdoor Spaces Working as One

The completed project looks dramatically different from the small second-story deck that originally occupied this part of the home.

What now stands in its place is a coordinated outdoor living environment designed around how the homeowners actually want to use their property.

On the upper level, approximately 250 square feet of TimberTech Legacy composite decking creates a substantial outdoor gathering space with the warmth and variation of hardwood and the lower maintenance requirements of capped composite decking.

Clear glass railing from American Structures & Design keeps the perimeter safe without visually closing in the deck, while fascia-mounted posts help preserve as much of the usable deck surface as possible.

A Finished Outdoor Room Below

Underneath the deck, the transformation may be even more dramatic.

The UnderCover Systems ClearSpan under-deck ceiling converts the underside of the elevated deck into a finished architectural ceiling while managing the rainwater from above.

Wood-grain steel ceiling panels add warmth to the space, while the integrated gutter and downspout system moves water away from the patio.

Instead of an area that would normally be wet whenever it rains, the homeowners now have a protected outdoor living space complete with recessed lighting, a ceiling-fan connection, structural swing mounts, and electrical heating.

Outdoor Living Beyond Summer

The addition of two Bromic Tungsten Smart-Heat electric heaters makes the finished patio much more practical during cooler Pacific Northwest weather.

Combined with the covered ceiling, recessed lighting, and protection from rain, the lower patio can now function more like an outdoor room than simply the space underneath a deck.

Meanwhile, the upper deck remains open for sunshine, entertaining, dining, and everyday outdoor use.

A Complete PCF Group Outdoor Living Project

This project is a good example of what becomes possible when the different pieces of an outdoor living project are designed together from the beginning.

The deck structure had to support and accommodate the MasterDecks construction above, the glass railing around the perimeter, the UnderCover Systems ceiling underneath, the patio-cover structure, electrical components, heaters, lighting, drainage, and future accessories.

Rather than approaching those as separate improvements, the project was engineered and built as one complete system.

From the structural footings hidden below grade to the TimberTech decking above and finished ceiling below, every layer contributes to an outdoor space that is dramatically more functional than what existed before.

The result is no longer simply a second-story deck. It's a multi-level outdoor living space built for entertaining, relaxing, and enjoying the outdoors through much more of the Pacific Northwest year.
