Isaac DeTurk had the barn built in 1891 as a horse stable. As one of the state's last true round barns -- the structure Isaac DeTurk built as a horse stable in 1891 has been painstakingly reborn as a city community center.

The state and national historical registrations for the structure dictated little could be done with the exterior. And the surrounding community made it clear to city officials that they didn't want new outbuildings in the surrounding park for a catering kitchen, restrooms and storage.

So all those functions had to be designed to fit inside the 68.5-foot-diameter building while leaving 7,500 square feet of banquet and meeting space on the main floor and mezzanine, according to TLCD Architecture principal architect Mark Adams.

The design and construction team pursued a “middle ground” adaptive-reuse approach for the inside.

“We could have gone ultramodern or we could have researched 1891 fixtures, but we went in between,” said TLCD project architect Kevin Teel.

Thus, the interior framing was left exposed. Because of that, Lunardi Electric consulted with TLCD on the installation of conduits and boxes to blend in when painted. Contractors also had to adjust their common methods to work with framing that was often neither square nor plumb.

The building has a high-tech audio-visual system that uses software and three projectors display undistorted, seamless video on a curved 18-foot-wide screen integrated into the mezzanine. The city originally wanted a 360-degree screen, but the 18 projectors required to accomplish that would have made up a significant amount of the project budget, according to Mr. Adams.

Sound-absorbing panels in the roof supports as well as wall curtains help control reverberations inherent in a round structure with a conical ceiling, especially with a speaker standing in the direct center of the ground floor.

To control temperatures in the space, a large ceiling fan and radiant heating were employed. During hot summer months, a 24-foot-diameter fan attached to a steel structure just below the roof supports will move up to 330,000 cubic feet of air per hour down through the mezzanine middle opening and back up around spaces between mezzanine and the exterior walls.

The steel structure was necessary to avoid having to upgrade the whole structure to modern building codes to handle the added weight of the fan, according to Mr. Adams.

To take the edge off the winter cold in the uninsulated building, coils embedded in top 2 inches of the 11- to 13-inch-thick ground-floor slab circulate hot water. Heat radiates through the reclaimed oak flooring, made from Asian shipping containers.

In another example of reuse, original redwood posts and beams that had to be replaced for seismic strength were milled into paneling for the stairwells, and more of the reclaimed oak was installed vertically around the elevator shaft.

To install the post-tension concrete slab and its components as well as repairing dry rotted bottom portions of the exterior walls, the whole barn was hoisted. A concrete hardscape perimeter now allows rainwater to flow off the gutterless roof as before without splashing rot-fostering mud on the walls.

Industrial contemporary Asian is the interior design theme for celebrity chef Masaharu Morimoto's much-anticipated Napa Valley restaurant. It was the first of three such high-end establishments to open in Channel Properties' The Riverfront downtown Napa mixed-use development, followed by Lark Creek Restaurant Group's Fish Story in August and Tyler Florence's Rotisserie & Wine in December.

Construction started in January 2010 with a strict six-month schedule to allow opening by July 4.

The interior look called for a lot of extra concrete -- almost too much, according to Jeff Baptista, project manager for Ledcor Construction. The bar and some of the walls were poured in place, and the bar top was precast. But the architectural design called for poured walls in the restrooms and two in the dining area, the weight of which concerned structural engineers. Instead, lighter-weight plaster wall panels were poured and stamped with the look of wood forms.

Reclaimed wood was used for built-in furniture and room dividers. Dozen-foot-long slabs of walnut were fashioned into the 10-seat sushi bar. For the dividers, Douglas fir boards were stacked lumber yard-style and spaced increasingly farther apart from floor to ceiling.

The third major restaurant newcomer to The Riverfront in downtown Napa was a Southern-style concept by another celebrity chef, Tyler Florence of Mill Valley.

While framing for the glazing at Morimoto Napa went heavy industrial with tube steel, one prominent element for this restaurant are the 3-inch-square timber-framed window frames painted black. Ledcor Construction's finish carpenters custom-built walnut cabinetry for the Mr. Florence's 15-seat restaurant counter and fitted it with a marble top.

Another prominent feature of the restaurant are the chandeliers custom-built by Richard Trujillo Barrel Designs of Napa. One features wine bottles hanging upside-down, and the other, wine barrels cut in half.

Interior construction of the 70-seat restaurant started in May 2010 and was completed in November, though the restaurant didn't open until early December.

The opening of the restaurant coincided with the opening of a Tyler Florence West Coast Kitchen Essentials store next door. It’s the third retail location for sales of his line of packaged food ingredients, created by Made in Napa Valley, as well as cookware and related items.
