With a professional working relationship spanning three decades, Gary F Martinez FAIA and Thomas E Johnson FAIA founded Martinez+Johnson Architecture in 1994 to bring their design sensitivities to institutional and cultural projects in urban locations. The 25-architect firm has since established an expertise in three main architectural areas – the restoration and adaptive reuse of historic structures, institutional buildings in urban areas and community settings, and the design and planning of performing arts venues.

Known for a thoughtful design approach to public facilities, M+J develops an intimate understanding of the needs of users, patrons, and operators destined to inhabit the projects of the firm. M+J looks to the future in their design aesthetic even when the context may be firmly rooted in the past and executes creative solutions to facilities both new and historic, where flexibility, ease of operation, and high but versatile performance characteristics are requisite. Venues express aspirational values and goals of the communities within which they are located, and at the same time conform to issues of economic value at the highest levels of environmental sustainability.

Planet Hollywood Showroom


Planet hollywood showroom

Las Vegas, Nevada

Martinez+Johnson was asked to design the 1,500-seat Showroom at the Planet Hollywood Resort and Casino in Las Vegas. The shell space in which the showroom is located was originally intended to house a 1,200-seat theatre but remained empty and was used as a storeroom.



Investigating how to increase the capacity of space for an additional 300 seats while providing operators with maximum seating configuration flexibility was a challenge M+J was excited to take on. Reconfiguring the empty facility as a flexible, high-quality theatre space while allowing the kitchen and main casino floor to remain operational throughout design and construction was up utmost importance.



M+J designed the state-of-the-art Showroom involving the addition of a new stage area, a modified fly tower, raked orchestra searing, tiered parterre level searing, and tiered balcony level seating. Utilizing M+J’s extensive experience with Broadway-style shows, the space was developed with the capacity for extended runs of larger productions typical of Las Vegas performances. The house has the ability to transform dramatically in both appearance and performance capabilities in order to meet the requirements of other types of productions. Raked seating was modified to large tiered platform area with cabaret style tables and chairs, and extended walkways installed.

Both front and back of house support spaces where designed with the new Showroom. A new lobby, concessions stands, and retail areas were devised to enhance the overall patron experience. Back-of-house development included performance and operations support facilities; fire, life safety, and building code requirements were given careful consideration as the project necessitated working with the existing egress pathways and fire suppression systems while seamlessly meshing them with the new assembly space requirements.
