TAG cross ventilation
Blurring inside and outside with opening walls!

Having worked on several cool projects in Hawai‘i over the last few years, our eyes have really been opened to architectural possibilities that rarely exist in New England. For example, we collaborated with Rhoady Lee Architecture and Design on the Big Island on a new house near the Four Seasons at Hualalai that had custom motorized rolling walls of glass and teak (detailed by our own Sandra Baron and Lilly Smith!) that disappear into lava rock walls, opening virtually every room in the house to trellised lanais, an edge-less pool, lushly landscaped courtyards, and sweet tropical breezes. So, how can we introduce these exotic possibilities to the custom houses we design in New England?
One answer is through bi-folding glass walls from companies like Nanawall, and we’ve designed several recent houses that utilize their exceptional technology. Our clients wanted to have large screened porches so they could live outdoors spring, summer and fall without the ubiquitous New England mosquitoes and flies, and wondered how they might join those porches to the rest of the house. Voila, we proposed Nanawall doors and something that has traditionally been a barrier in older New England houses becomes an opportunity. Added benefit: makes a great party house even better!

Modern Hawaiian Lanais (part II, hotels)

After a very long, exhausting day flying from Boston to the Big Island of Hawai‘i, and after a bizarre drive across seemingly endless miles of lava – usually at night with little sense of scale – harried visitors are often welcomed by a warm “aloha”, friendly faces, cool towels, fresh guava juice, and hotels unlike anything most of us have seen before. Who knew that hotels didn’t really need walls? As with Hawaiian houses, the main public spaces of most Hawaiian hotels are essentially large open air lanais; no screens as you would find in the Caribbean since flying insects are less prevalent in Hawai‘i, and it is rare to see the discrete bi-folding shutters or sliding skylights closed. The next morning you wake up, and you see views like those below. Pure heaven! And fresh ideas for how these design possibilities might translate into our own work on custom vacation houses in New England…

- One of William Ruhl’s (principal of Ruhl Walker Architects) favorite hotels on the Big Island is the Mauna Kea Beach Hotel, designed by SOM and completed in 1965. All of the public spaces are cooled naturally by being designed without walls, taking advantage of the trade winds and natural convection, and allowing uninterrupted views of the magnificent coastline.
- One of Mauna Kea’s open air restaurants, Manta, overlooking Kauna‘oa Beach, one of Hawaii’s most breath-taking beaches. And yes, you do occasionally run into manta rays as you snorkel, and during dinner.
- The inversely-stepped profile of the Mauna Kea’s main lobby enhances the natural cooling of the space, with cool breezes flowing freely and warm air disappearing through the roof openings.

- Another favorite hotel on the Big Island is the Four Seasons Hualalai. As with many other Hawaiian hotels, all public spaces are open air, with bi-folding screen and/or glass panels providing protection during the occasional inclement weather. Above and to the right is Pahu i‘a restaurant, directly on the beach. Just magnificent…
- Without walls, views are infinite and fresh air is abundant.
- The Four Season’s lobby is a separate pavilion (“hale” in Hawaiian) which is essentially open to the elements but does have sliding and bi-folding glass doors in case of (rare) inclement weather.
- You have to look pretty hard to see the glass and mahogany doors in the main lobby (lanai) of the Four Seasons. Furnishings are perhaps a bit too faux-historic, but sure are comfortable…
Modern Hawaiian Lanais (Part I, houses)

Having just returned from the Big Island of Hawai‘i – the first time in five years not related at least partially to working with the Hawai‘i Wildlife Center – I still have Hawai‘i on my mind… It doesn’t help that the temperatures dipped into single digits this weekend, with wind chills below zero!
Architects have a hard time traveling without focusing obsessively on local architecture, and Hawaii’s – the openness to the elements, the blurring of inside and outside, the direct link to Asian architecture in both form and spatial flow – is particularly alluring. One key element is the “lanai”, a term first used in Hawai‘i in the early eighteenth century, and elsewhere known generically as a porch or veranda. The Hawaiian Islands are well known for their steady tropical breezes, a benefit and sometimes curse of being located so remotely in the middle of the Pacific Ocean. Hawaiian lanais are often a house’s primary living space, and provide much needed shade and help Hawaiian buildings breathe by catching the trade winds and using that constant supply of fresh, naturally cooled (by the Pacific) air to remove hotter, more stagnant air. Below are a few of my favorite examples of modern lanais.
Send us your own images and thoughts! And look forward to future posts showing how we bring this “exotic” knowledge to our New England projects!

The Hawai‘i Wildlife Center has its official opening!
Last Saturday, November 19th, our Hawai‘i Wildlife Center had its official opening, and Will Ruhl and Sandra Baron were fortunate to be able to be in Kapa‘au to represent Ruhl Walker Architects in paradise. We were joined by our Associate Architects and great friends Rhoady Lee and Aaron Spielman of Rhoady Lee Architecture + Design, our landscape architects Jason Umemoto and Nancy Cassandro of Umemoto Cassandro Design, the rest of our talented (and pro bono) design and engineering team, the general contractor and many of his incredibly generous sub-contractors (many if not most of whom had donated or discounted their time and material costs), and hundreds of neighbors, family, and friends.
The celebration began with a quietly beautiful and poetic blessing of the Center by Kumu Hula Raylene Ha‘alelea Kawaiaea, and also included some other visiting dignitaries who publicly declared their support, like John Buckstead of Governor Abercrombie’s office in Honolulu, who spoke on behalf of the Governor, who declared November 19th, 2011 as the official day of the Hawai‘i Wildlife Center. In between the speeches, entertainment was provided by students of the nearby Kohala Middle School, as well as the Kohala Hula group, Halau Kalaniumi Aliloa O Hawai‘i Nei, and topped off by the Grammy Award winning slack key guitarist John Keawe. There is always an element of bittersweet sadness at the end of a project, for clients and architects alike, but the focus of the day was on the path that led us to this point, and on the new beginning of the HWC’s important efforts to protect and rehabilitate the native flora and fauna of this magical place.
Though the project has a (small) punch list still to complete, the Certificate of Occupancy is in hand and “all” that is left to do is construct the pens and pools in the fenced-in rehabilitation yard for the expected endangered native species, build the custom pens for the recovery rooms, connect the custom hoses for the wash-rinse room (for handling any future oil-soaked animals in the event of an oil spill), install the rooftop solar photovoltaic array and the water-collection catchment system, deliver the triage room furniture, install building signage and educational displays, hire staff, and … raise some money for operations! We hope you will consider joining us in donating online to this wonderful and critically important environmental organization; just click here! Mahalo!

Westport River house is complete!

It’s been awhile since we posted an update for our Westport project, the modern house Ruhl Walker Architects designed to float above its Westport River site, and that we introduced back in January and April. Rick and Susan have moved in and were even able to enjoy the summer while some finish work and landscaping continued. We directly benefited from some of this fun, not only because Rick and Susan were in such good spirits and kept telling us how much they loved their new house, but also because we were treated to an amazing feast with our design partners from Reed Hilderbrand and Oblio Design on August 6th. Out of a great project experience have grown some wonderful friendships!
A few weeks after the celebration, Will Ruhl returned to discuss the “punch list”, which was unusually short given the excellent craftsmanship provided by the general contractor, Gilman, Guidelli, Bellow, & Co. It was actually more of a list of potential design modifications, minor tweaks to fine tune a few of the built details. Some fun work for Rick to ponder this fall!
Reed Hilderbrand’s landscape design is looking great already, and thanks to a violent rainstorm we witnessed first hand the wonderfully interactive water gathering rock gardens that coordinate perfectly with the house’s scuppers and waterfall element.
We are excited about some publication possibilities that have already come our way; publish or die… Keep tuned in for updates on that!
Hawai’i Wildlife Center featured in ArchDaily

The Hawai’i Wildlife Center, designed by Ruhl Walker Architects, was featured in ArchDaily on August 20th. ArchDaily is one of the leading and most influential architecture website in the world, and gets over two million visits and eighteen million page impressions per month according to Google Analytics.
Please visit our portfolio website for additional information on the design of the HWC, and join us in supporting this critically important environmental cause by visiting the HWC’s online donation page!

The exterior of the HWC has been completed, and the interiors will be finished in November, in time for a grand opening celebration on November 19th.

Ruhl Walker Architects is providing pro bono design services for several affordable / sustainable house prototypes to be built in the Summer of 2012 in Kailua-Kona, Hawai’i, as part of “Blitz Build”, an annual event undertaken at different locations around the country by Blitz Home Builders, an international group of Habitat for Humanity volunteers that have organized annual Blitz Builds since 1996.
The Blitz Build will take place from September 12-22, 2012, in Kailua-Kona on the west (dry) side of the Big Island. The West Hawai’i affiliate of Habitat for Humanity hopes to build up to five houses in this 10-day span! These homes will be similar to the Habitat homes built on the mainland, but will have some unique design features suitable for the heavenly Hawaiian climate. Please visit the Hawaii ’12 page on Blitz Home Builder’s website for additional information.
Ruhl Walker has begun preliminary design work on two prototypes that will be presented to Habitat West Hawaii’s Building Committee later this year. The plan features a covered deck or lanai, an open living / dining / kitchen with sliding glass doors leading to the lanai, and a screened porch / hallway leading to 2 bedrooms and a shared bath. The proportions of the house — 16’-0” wide by 60’-0” long — allow for simple wood framing and ample cross ventilation; the covered lanai and screened hallway further enhance natural cross ventilation. One side of the house has fewer / smaller windows and would be oriented towards the prevailing trade winds, and the other sides would have larger windows and generous overhangs and be oriented towards the sea (“makai”). The screened hallway would have painted studs 24” on center and horizontal battens 12” on center, and the resulting grid would read as a large window. Materials under consideration are composite siding and trim on the makai side of the house as well as the end elevations, and corrugated metal siding on the windward side.
The images below are very preliminary. We look forward to posting updates as our design work – and ultimately construction – continues.
Making great progress at the Hawai’i Wildlife Center
The new native species gardens are growing in nicely at the new facility Ruhl Walker Architects designed for the Hawai’i Wildlife Center on the Big Island of Hawai’i, and the construction team at TDI is making great progress towards the official opening in November. Rough plumbing, electrical, and mechanical work are installed and ready for the interior finish work.
Our partners at Rhoady Lee Architecture and Design are managing the day to day construction administration process which is great except it means for Will there is no longer a regular excuse to visit the islands, unlike the last few years… It’s been great collaborating with Rhoady and Aaron; they’ve been helping us on the HWC, and we’ve in turn collaborated with them on several residential projects, including a recently completed house at the Hualalai Resort, home to the fabulous Four Seasons. In fact, our senior associate, Sandra Baron, spent 6 weeks working in their office in Waimea during the detailing push for that house, 3 weeks each on two separate occasions. Aaron, when are you coming to Boston?!
The outpouring of community support for the HWC continues to be amazing. On June 15th, a contingent of Marines – members of Wing Support Squadron 171, stationed in Iwakuni, Japan, but currently training at the Pohakuloa Training Area on the Big Island – joined Linda Elliott and others to assemble enormous lava rock slabs into benches and tables within the interpretive courtyard. The slabs had been donated by Ryan Associates.
November can’t come soon enough!

Moving in to the (almost finished) Mystic Lake House
Ruhl Walker’s modern house on Mystic Lake is nearing completion and the owners have moved in, while meanwhile crews are still scrambling to finish the exterior. In fact, work is still on-going on the inside too, so living in the house is quite a challenge! But the movers had already been rescheduled twice, everything was packed, and the construction crews doubled down to make at least a partial move-in possible.
The interior stair railings were recently completed, after two separate steel fabricators’ equipment broke while trying to drill holes in the stainless steel posts for the cable rail system. The off-the-shelf railing system – by the Italian company Indital – was substantially less flexible and customizable than anticipated, but the installers went above and beyond to make everything work out smoothly in the end. Painters, tilers, carpenters, plasterers, plumbers, electricians, and landscape crews all competed for the same limited time and space. Everyone was trying their best to overcome the time lost to inclement weather over the brutal winter and wet spring.
One highlight of this last few weeks was the delivery of the dozens of slabs of granite, bought for next to nothing from the general contractor working on IKEA’s new store in Somerville; without our intrepid (and persistent) client, all of the granite curbs would have been dumped at a landfill, but are now beautifully choreographed per Matthew Cunningham’s brilliant landscape design. Saving money and being “green”…
So, with a month left before the babies are due, every day is still full of noise and commotion, but the end is in sight, and the magnificent views of the lake are at least a calming influence after the crews leave…
Loving their new (almost finished) Westport River House
We are thrilled that our Westport clients are enjoying living in their new river front house, after recently having received their Certificate of Occupancy from the town! There is still an extensive punch list to complete, but after such a long, snowy winter and an unusually rainy spring, that first coffee on the new deck was extra special…
We do our best to address our clients’ expectations throughout the design and construction process; but because every client is so unique, each project has its own unique and ever-changing set of expectations. In most cases the design process is quite fun, perhaps because the focus is on hopes and dreams. But most of our clients would not describe the construction process as fun… Maintaining some perspective is the goal, remembering that there is an end to the often stressful process, and trying to find some humor in the occasionally ridiculous process of residential construction. In this case, the focus was on that mid-summer coffee on the deck, watching the river flow by…
