The Call for a Practical Rooftop Living Space

With yards shrinking, the rooftop deck answers the need for outdoor space

As Seattle housing becomes more compact and dense, the expansive backyard with green grass, lawn chairs and a barbecue grill is fast becoming obsolete. To compensate, Seattleites are looking skyward for open space. With the proliferation of new, boxy “modern” homes, Seattle’s house parties are, literally, being taken to a whole new level.  

“That form of house [with its linear, simplistic design and bold roof lines] lends itself to these rooftop decks,” says Robert Humble, owner and principal of Seattle-based design and development firm HyBrid Architecture & Assembly, whose company has incorporated the spaces into homes throughout the city.

Those in the market for a new or remodeled home are increasingly asking for rooftop open space, says Humble. In neighborhoods such as Capitol Hill and Ballard, where space is tight, rooftop decks are particularly sensible. While a tiny front yard might be enough for a folding lawn chair, a rooftop deck provides plenty of space for entertaining.

But be aware that your expansive party palace comes at a cost. Humble has a rooftop deck atop his modern-style Central District home, but admits that it took a few years and a significant amount of money to transform it into the entertainment space it is today. To turn a barren rooftop deck into a livable space means adding a number of elements including tables, chairs and comfy couches, as well as planters and plants.

Infrastructure is also important. Gas lines, water lines and electricity allow you to add a gas fire pit, running water or a small kitchen. Without these amenities, homeowners can find themselves shuttling food and drinks up to the roof from a kitchen. Gas fire pits can provide warmth when the sun goes down and are handy for toasting marshmallows. As for furnishings, many retailers offer modular seating systems made with materials designed to weather the elements. Humble says large tropical plants in equally large pots are also surprisingly amenable to rooftop living, thriving in direct sun and faring well despite winds. 

Creative plantings also can provide some privacy, but don’t overdo it. This is urban living, after all. “You can wall yourself off from your neighbors, but I don’t think that’s what city living is really about,” Humble says. “It’s nicer to create an inviting, open space on the roof that you and your neighbors can enjoy.”

AIA Home: Goodbye 1970

Family fixes design flaws to bring midcentury home into modern era

“Treehouse” by Floisand Studio Architects returns to glory a Ralph D. Anderson home that had lost its compass. Nick and Rachel Lenington purchased the 1970 Mercer Island home in 2010, attracted to the quiet neighborhood because of its midcentury vibe, big, west-facing windows, and abundant wildlife. An advertised water view didn’t really pan out, but…

Living: This Kitchen Really Cooks

Remodel preserves Victorian charm

Raised on an off-the-grid ranch in southern Oregon, Mandy Lozano took a don’t-fence-me-in approach to renovating her kitchen in Seattle’s Squire Park neighborhood. She sought to balance a respect for the 1900 Victorian’s heritage with a genetic predisposition toward creative license. “I don’t care for modern technology that much, and I don’t like fussy or…

It Costs What? High-End Seattle-Area Homes Skyrocket in Price

The rise in pricey homes throughout Seattle is nothing short of astonishing

It’s no secret that housing prices are skyrocketing. Some new numbers, however, may send you into a fit of apoplexy. A study by home buying and selling service Orchard finds that the Seattle region has experienced a whopping 180% increase in the sale of million-dollar homes in just three years. So far in 2022, almost…

The roof slopes to the south for greater solar-panel efficiency and the one-car garage was among several tradeoffs to improve energy efficiency.

Seattle Passive House Respects The Environment

Passive House in Ballard treats the environment with respect

Rade and Eli Trimceski didn’t set out to save the planet when they commissioned their new home in Ballard, but the planet sent its regards anyway.

Why This Tiny Cottage in Shoreline Works For a Family of Four

Why our tiny house makes sense

We live in a world full of hacks, loopholes and workarounds that often lead to more work and dead ends. When my wife, Kristy, and I discovered a way to live mortgage free, it seemed too good to be true. There had to be a catch. Six years later, we are still living out that…

The project resulted in an extra 5,000 square feet of floor space and a refacing of parts of the facade.

Seattle’s Former Columbia Congregational Church and Allied8: A Match Made in Heaven

The former Columbia Congregational Church was in disrepair before architectural firm Allied8 came to the rescue

The Columbia Congregational Church was harshly thrust into an uncertain future in the secular world.   It was founded in 1891, two years before the Columbia City neighborhood. The densely forested site was ringed by marshlands and served as the gateway to the untamed Rainier Valley. At the time, it was a common practice to donate…
