Office design might be one of the few things in Las Vegas that bears no trace of flamboyance. The city’s corporate architectural scene is easily overlooked by the splendor of the landmark casinos running up and down The Strip. Perhaps that is because so few corporations not in the resorts and hotel market have made their home in Vegas. Or, it could be due to the tempering influence of the harsh desert climate. But if function and visual appeal set the standards, then Sin City’s business offices meet the mark. And that is largely because of the firms listed here. Whether the firm’s reach is nationwide or global, each has put careful research into designing spaces that have every right to call themselves workplace wellness zones. The ranking here is straightforward: by project scope, client prestige, and depth of vision.

Top Architects

Simpson Coulter Studio

Sean Coulter and Wade Simpson

AIA Nevada Excellence in Design Award,
AIA Nevada Architecture Firm Award

151 Warm Springs Road, Las Vegas, NV 89119

About Simpson Coulter Studio

Up until 2010, this firm had been known as Pugsley Simpson Coulter Architects, which was founded in 1991 in Vegas by Sean Coulter, a member of the American Institute of Architects (AIA) and a Leadership in Energy and Environmental Design Advanced Professional (LEED AP), and Wade Simpson, AIA, LEED AP. Coulter studied architecture at Louisiana Tech University, then interned at Century A&E in Grand Rapids, MI, and then at Tate Snyder Kimsey Architects, which has offices in Nevada, California, and China. Simpson received his master’s from the University of Utah, then spent six years at Richard D. Chong & Associates in Salt Lake City. After a two-year stint at Los Angeles-based Rochlin, Barron & Balbona Architects, he joined Coulter in 1992 at Simpson Coulter Studio, which was founded in 1968. The firm’s design team includes at least 10 licensed architects and one licensed interior designer. In addition to designing office and commercial spaces, its projects cover the fields of education, hospitality, libraries, community, retail, transportation, and residential mixed-use. Two AIA Nevada Architecture Firm Awards were given in 2013 and 2013.

Featured Projects

Simpson Coulter was pegged by Perini Building Company, one of the largest construction enterprises in the world, to build its corporate headquarters in Vegas. The design needed to highlight Perini’s high standards for building excellence. The plan included spaces for conference rooms, executive offices, an accounting department, and a large venue for training classes. The physical site of the building required a structure resembling an arc, with two arms leading to a parking lot. A focal point was the entrance lobby, as the challenge was to create a soft environment that allowed visitors to transition in from the desert climate. The project earned the NAIOP Spotlight Award in 2010. At a corner lot in Las Vegas Valley, the firm planned an addition to Lotus Broadcasting Studios. The work for the 14k-square-foot building was done around a restricted budget. A goal of the design was to have the Lotus Studios “speak” to the surrounding Red Rock Mountains with a warehouse and open-office concept. The actual Studio was placed at the front of the site so that it appeared to be linked to downtown Las Vegas.

Design Cell

Scott Brown
Kastytis Cechavicius

1725 Village Center Circle #110, Las Vegas, Nevada 89134

About Design Cell

The principals of Design Cell met while both worked at a leading Vegas firm, JMA Architecture Studios. Scott Brown, a member of the National Council of Architectural Registration Boards (NCARB), earned his bachelor’s and master’s at the University of Utah. He was a project professional at Salt Lake City’s Shiel Architects and then project manager at JMA. Today, he is principal of Design Cell Architecture, the Las Vegas-based firm he founded in 2007. Co-founder Kastytis Cechavicius studied first in his native Lithuania, then at the University of Cambridge in England and finally in Las Vegas, at the University of Nevada. After graduating, Kastytis became a senior designer at JMA. He is LEED Accredited and licensed several states. Concept design, construction documents and drawings, and site planning are Design Cell’s specialties. Though the firm is just celebrating its 10 years in business, it has already expanded its client base through Oregon, Washington, Utah, California, Texas, Arizona, Colorado, North Dakota, and Utah.

Featured Projects

A break came for Design Cell when multinational JS Products, Inc., a manufacturer and distributor of specialty automotive tools, selected it to improve its corporate offices and warehouse on Montessouri Street. The facilities were housed in a 70k-square-foot shell building and 23k-square-foot office. Design Cell created two two-story offices inside the warehouse, building out corporate departments, a product showroom, and conference areas. A lounge looks down upon a two-tiered lobby. An office project in Henderson gave Design Cell a platform to demonstrate its design build services in a corporate setting. A tenant in Windmill wanted a modern overhaul for its 4,000 square feet of office space. The existing structure allowed plenty of design options — a large lobby, data centers, conference rooms, and private offices. Design Cell’s plan broke from standard office design, with colorful workspaces, futuristic looking cubicles, unique floor lamps, and crisp, clean contours.

Aptus Group

R. Brandon Sprague
Kristen Goodell

1200 South 4th Street, Suite 206, Las Vegas, NV 89104

About Aptus Group

Las Vegas is just one office location for Aptus, which touts itself as more than just an architecture firm. Interior design and planning are also a big part of what Aptus does. Principal R. Brandon Sprague, AIA, founded the company in 2003. His bachelor’s came from the University of New Mexico and his master’s from the University of Illinois at Urbana-Champaign. Principal Kristen Goodell, AIA, studied architecture at the University of Nevada-Las Vegas and earned the five-year bachelor of architecture from the University of Arizona. Within two years of graduation, she was a project manager at Albuquerque-based architecture firm Dekker Perich Sabatini, until 2004, when she joined Aptus as director of the Las Vegas location. The firm specializes in retail, hospitality, mixed-use, workplace, and public projects in Nevada, and in Illinois and California, where it also maintains offices.

Featured Projects

For client Zappos.com, the online shopping giant, Aptus took on an office expansion project for the company’s main building in Henderson. The 27k-square-foot space was built out into a modern and collaborative office environment that balanced form and function. Five departments were revamped, training facilities for customer service new-hires were added, and the lobby was redesigned with a smarter ebb-and-flow pattern. Aptus even built a game room, sleep room, and extra staff break room. The project was finished in 2010. When The Cosmopolitan of Las Vegas needed work on its offsite offices, it chose Aptus to handle the 35k-square-foot project. The client did not want a traditional office design. The challenge was to consolidate nine departments into one operations center that fostered a teamwork approach. After meeting with Cosmopolitan leaders, Aptus understood the corporation’s goals and functions. It used bubble diagrams to create a layout the client could modify. Aptus took those modifications and designed an organizational plan that matched the client’s vision.

LG Architects, Inc.

Craig Galati
Jason Jorjorian,

AIA Nevada Service Award,
AIA Nevada Silver Medal,
NAIOP Outstanding Project Award

241 West Charleston Boulevard, Suite 107, Las Vegas, Nevada, 89102

About LG Architects, Inc.

This firm, which keeps a low profile, has a website that reveals its playful side. A page in the office profile is devoted to Elvis Presley. Apparently, the King of Rock & Roll inspires the firm’s designs through his music. Low profile or not, LGA has a solid reputation throughout the Vegas metro area, which becomes obvious when searching architect and building databases. Principal Craig Galati, AIA, FSMPS, CPSM, is still on board here, providing strategy for the firm’s impressive projects in the community, education, wellness, and workplace culture sectors. Galati has received the AIA Nevada Service Award and AIA Nevada Silver Medal. He’s been with LGA since 1988. Principal Jason Jorjorian, LEED AP, is LGA’s project manager. His degrees came from the University of Nevada at Las Vegas. Jormorian has been with LGA for 19 years. The firm made local headlines in 2014 for its design of the headquarters visitors center at Mount Charleston, which covers 316k acres of the Spring Mountain National Recreation Area. In 2002, the firm was honored with the AIA Nevada Distinguished Service Award.

Featured Projects

Turntable Health, a project by Zappos CEO Tony Hsieh, was part of a $350M project to spur economic development in downtown Las Vegas. It offered primary care through a clinic available to individuals through their employers. LGA became part of this project when it was commissioned to design about 7,800 square feet of the Wellness Center’s reception, examination rooms, open staff work areas, lab rooms, huddle areas, yoga/exercise studios, gyms, and kitchen/juice bars. LGA also won the project to help fast-growing public relations firm R&R Partners expand when its existing 17k square feet of space became too tight. R&R’s success allowed it to commission a big-budget project that had LGA designing a new corporate headquarters. LGA’s plans were to create a futuristic design in keeping with the client’s forward-thinking business model, which depended on professionals interconnecting all day. For its efforts, LGA was rewarded handsomely: a 2002 Outstanding Project Award and an NAIOP Spotlight Awards for an Interiors Project.

Carpenter Sellers Del Gatto Architects

NAIOP of Southern Nevada Chapter 2016,
2014 Architecture Firm of the Year Awards,
AIA Nevada Firm of the Year Award in 1999

8882 Spanish Ridge Avenue, Las Vegas, NV 89148

About Carpenter Sellers Del Gatto Architects

This Southern Nevada firm has earned more than 100 design awards since its founding in 1986. Principal and President Rick Sellers, AIA, received the AIA Nevada Young Architect Citation in 1997 to honor his design contributions in the community. His highest profile projects – in public works, federal, commercial, retail, and healthcare – include the 660k-square-foot University of Phoenix Riverpoint Center and the Andre Agassi College Preparatory Academy. Principal Mike Del Gao serves as vice president. He studied architecture at the University of Nevada at Las Vegas and has served on the Board of Directors of AIA’s chapter in Vegas. In 2006, Del Gatto received the AIA Young Architect Citation Award, and in 2007 he was listed on the Nevada Business Journal’s “40 under 40.” Through the years, the firm has received numerous NAIOP Merit Awards for office additions in the Vegas metro area.

Featured Projects

Carpenter Sellers was chosen by online shoe and clothing giant Zappos to transform and remodel its corporate headquarters in Vegas. One caveat was that the offices had to reflect the company’s core values, which include growth and learning, adventure, fun, a positive team and family spirit, and passion and determination. The renovations and improvements totaled 300k square feet. Structures built in the 1950s had to be turned into creative and high-tech environments for a largely millennial workforce. Also in Vegas are the Mandelbaum Schwartz Law Offices, a 5,890-square-foot project made especially challenging by the desert climate. An entrance features a glass wall shaded with perforated metal to create the illusion of navigating through a canyon with hiding places. The metal also serves to protect from the sun while flooding the lobby with natural light.

900 South Pavilion Center Drive, Suite 180, Las Vegas, NV 89144

About Ed Vance & Associates Architects

Edward and Jonelle Vance founded this firm in 2006, and their combined architecture experience has made them one of the most prominent architecture and design firms in the area. Edward studied architecture at North Dakota State University. He is FAIA and NCARB and is licensed in seven states. His pre-EVA work included serving as president of JMA Architecture Studios, which has a national reputation. Among his degrees are the AIA Nevada Silver Medal and the AIA Nevada Young Architect Citation. Vance was also a member of AIA’s national Board of Directors for three years. Jonelle serves as executive vice president. She is certified with the Council for Interior Design Qualification (NCIDQ) and is an LEED AP, having studied art and design at Avia College. Like Edward, she learned the trade at JMA, where she served as project manager and principal-in-charge. Among the firm’s prestigious builds is the Las Vegas Convention Center, the Dynasty Resort Hotel & Casino, and the Lucky Dragon Hotel & Casino.

Featured Projects

Not only did EVA complete the shell buildings for the 5M-square-foot World Market Center, it also built and designed the interiors of the buildings that followed. Each floor was about 100k square feet. The most recent project was Floor 16, to house the offices of International Market Center’s management group. Project features include a raised floor with work areas and an adventurous environment for IMC staff. Another Vegas office build was the 20k square feet of space for Alterra Home Loans. This required planning the design concept and space and handling the architecture drawings. The space is divided between private offices and modular workstations. Glass-front offices and a color palette of gray, taupe, and white created a sleek, modern look. One of EVA’s crowning achievements was the build and design of the corporate headquarters for The Howard Hughes Corporation in Vegas at One Summerlin. An open office concept was created for the 25k-square-foot area. Warm wood walls and neutral-colored stones created a luxurious lobby and board room. EVA’s goal was to create a modern look with clean lines to showcase the HHC’s standing in the Vegas community.

Design Futures Council Lifetime Achievement Award

3883 Howard Hughes Parkway, Suite 650, Las Vegas, NV 89169

About Gensler

Las Vegas is just one of the 44 locations worldwide that industry leader Gensler operates. Here are a few more facts about the world’s largest architecture enterprise: In 2016, Gensler reported global revenue to be $1.142B. Each year, ENR (Engineering News Record) puts out a list of the top design firms, and in 2016 Gensler took the number one spot. And the firm’s client list runs into the thousands — 3,500 to be exact. Those clients, says Gensler, are in almost every industry. Its projects span 32 practice areas, from arts and culture to defense and aerospace, and are spread throughout North America, South America, Europe, the Middle East, and Asia Pacific. Gensler was started in San Francisco in 1965. Its founder was Art Gensler, a fellow of the AIA and the International Interior Design Association (FIIDA) and a member of the Royal Institute of British Architects (RIBA), who received the Design Futures Council’s Lifetime Achievement Award.

Featured Projects

When Pinnacle Entertainment merged with Ameristar Casinos, it selected Gensler to design offices that encouraged flexibility and teamwork that is vital to the company’s bottom line. For the project, Gensler centralized the corporate headquarters that had existed in many buildings into one. The new offices allow a variety of work settings: private offices down the perimeter with relaxed and private areas for individual study or open spaces for collaboration. The design is modern and sleek. Also anchored in Vegas is Allegiant Airlines, which had to expand its Summerlin facilities to house a growing staff. Allegiant, too, wanted a community-driven work environment. Gensler consolidated the offices into three buildings, designed workstations with lower partitions, and reduced the number of private offices. There is also a courtyard with canopies for the company’s social gatherings.

Novus Architecture

Dwayne R. Eshenbaugh

Daryl B. Dobras Award for Outstanding Graduate Student,
NEWH Top Design Firm

8 E. Charleston Boulevard, Las Vegas, Nevada 89104

About Novus Architecture

The current principal and founder of NOVUS, Dwayne R. Eshenbaugh, is a veteran of the US Air Force and serves on the AIA Las Vegas Board of Directors. Eshenbaugh’s success in architecture began long before he founded this firm in 2009. It started when he was earning his bachelor’s at the University of Nevada, Las Vegas. He was president of the AIA Student Chapter at the school and then was awarded a Citation in The Leading Edge Design Competition by the Southern California Edison. There was much the same in graduate school at the University of Arizona, where he received the Daryl B. Dobras Award for Outstanding Graduate Student in 1997. Eshenbaugh’s team is just as impressive. Marco Gonzalez, Associate AIA, NCARB, is senior project manager at Novus. Gonzalez earned his bachelor’s and master’s at Texas Tech University, then worked as an intern at the prestigious Dekker Perich Sabatini. In 2016, Novus was recognized as the Top Design Firm by the NEWH. In addition to office architecture, the firm handles projects in hospitality, healthcare, commercial, and education sectors.

Featured Projects

Lik USA, founded by the Australian artist who operates art galleries, selected Novus to build its 10k-square-foot corporate headquarters on West Badura Avenue. The project, which was completed in 2014, required turning warehouse space into an open, contemporary office plan and enjoyable work environment. Another corporate headquarters project by Novus was for Energy Inspectors, a company that has served the construction and homebuilding industries as an energy consultant since 1996. The structure is on South Miller Lane. The project involved testing laboratories, training rooms, and office interiors. Novus created an open interior: ceilings are high and windows can open. It achieved the goal of net-zero energy. Not only was energy consumption reduced to 48 percent, but water consumption was cut in half. The U.S. Green Building Council gave the project LEED Gold Certification. It was completed in 2015.


Ralph Korte
Todd Korte

AIA Achievment Award,
NAIOP Las Vegas Contractor of the Year

9225 W. Flamingo Road, Suite 100, Las Vegas, NV 89147

About Korte

This multidisciplinary firm has offices in Vegas, in Missouri, Illinois, and Oklahoma. Its projects range from entertainment to places of worship. It began in 1958 as a construction company in Illinois, started by a war veteran who ran the business by day and attended college at night. Ralph Korte not only knew construction, he knew how to build a business. His expertise was sought by the Design-Build Institute of America during its developmental stage. Korte was one of the first companies nationwide to handle LEED-Certified projects. Gradually, he added interior designers and architects to the team and branched out into other states, including Nevada, where Korte either collaborates with local architects or handles the architecture itself. In addition to architecture, the firm does surveying, historic building renovation, assessments, general contracting, and construction management. Korte’s clients include Hershey’s, Kraft, Anheuser-Busch, the US Air Force, and NASA.

Featured Projects

Korte was called upon to renovate United Way of Southern Nevada’s offices on West Flamingo Road. It was an extensive demolition project that ended with Korte building out new executive and administrative offices, conference rooms, and the HVAC system, and installing casework, new ceilings, and floor coverings. Another of Korte’s office building projects was to design eye-catching tenant renovations at the corporate headquarters of publisher Greenspun Media Group on Corporate Circle in Henderson. The project ended up earning an LEED Silver Certification from the US Green Building council. Korte handled the architecture, interior design, contracting, and space planning. The design featured backlighting and sculpted plaster, and translucent acrylic panels to dress up the reception area. A communicating stairway links to a conference area that seats 60 and to spectacular views of the Strip and nearby mountains.

About JMA

This Summerlin-based firm has been a prominent part of the architecture world in Vegas for over seven decades. The firm was founded in 1945 by Jack Miller, who built it into the largest architecture firm in the city and the 45th largest in the country. JMA has designed most of the architectural landmarks in Southern Nevada, such as the Atomic Testing Museum and One Queensridge Place. Many of the big names in Vegas architecture today got their start at JMA. The firm is known for its meticulous architecture, planning, and interior design practices that were used to complete multimillion-dollar projects, such as the US Veteran’s Administration Medical Center, Las Vegas City Hall, and the Morse Arberry, Jr. Telecommunication Building at the College of Southern Nevada. In 2010, JMA reported $10M in revenue. The following year, it was purchased by Michael Baker Corporation. Principal Thomas Schoenman, who has been with JMA since 1979, remains as its chief executive officer.

Featured Projects

JMA was commissioned by Konami Corporation of Japan to expand the entertainment company’s corporate offices at 585 Trade Center Drive, near McCarran International Airport. During the project’s first stage, a 193k-square-foot building was erected. Next, the existing 123k-square-foot facility — which housed over 400 employees — was completely renovated. But few of JMA’s office design projects compare to the 12M square feet of office, showroom, and convention space it built for client World Market Center. The client needed a spectacular venue for its showroom of home furnishings that is the largest in the world. JMA was the architect of record on the job, which consisted of eight separate buildings, including a 10-story structure with 1.3M square feet of showrooms. The project highlights include a façade fashioned out of titanium and glass in the form of a half-sphere that wraps around a geometric shape. This design was inspired by the imaginative process that goes into furnishing a home. Circling the façade are glass arcs that appear to light up at night, resembling a glowing icon. The Center — now a landmark — also spurred a flurry of redevelopment in downtown Vegas.
