Highrise in a sustainable city

Make a Place

The proposed design seeks to advance the City of Phoenix onto the world stage of architectural design, urban planning, and sustainable living, by a sophisticated integration of vertically mixed uses, transportation infrastructure, and urban farming. This design addresses and solves the long term planning for a self sustaining society. The forward thinking concept consists of two towers that reach over the new proposed light rail line and incorporates a transit stop that will serve as the “nucleus” of the well shaded public space at the ground floor.

The two towers each serve a specific purpose integrated together. The larger tower to the north is programmed as a “city within a city”. Public amenities such as schools, medical facilities, and public services are interconnected via “transfer” floors that link with the various program. The tower to the south serves a “multi-functional greenhouse”. Maximizing the proposed 14 acres of vertical urban farming utilizing hydroponics to support the residents of the vertically integrated neighborhood.

The structure consists of a continuous high strength concrete core with walls varying in thickness. The perimeter is an “organic grid” of composite steel and concrete diagonal members organized in primary, secondary, and tertiary hierarchy, corresponding to their principal functions. Steel bridges connect each of the towers developing “super floors” of public amenities and outdoor spaces.

West Elevation 08 16 15
The relatively small foot print at the ground floor sets an opportunity to maximize shaded multi-use public spaces with a “solar shade” of advanced photo-voltaic system. The existing rail line will be converted to a new light rail connecting and advancing the light rail infrastructure. The transit stop will serve as a critical aspect in advancing sustainable urban living.

The innovative formal concept of the towers sets a powerful expression on the City of Phoenix skyline. The sculptural nature of the structural form appropriates an identity which is part modern and part space age. Like the young city of Phoenix it shares a strong optimism and professionalism.

The Jefferson

Jan 07, 2015 » Leave a Comment

As we are in the process of transforming and giving new light to the building, the once Barrister building will be renamed back to The Jefferson, keeping intact its legacy and history for excellence.



In 1915, the City of Phoenix was very eager for the Jefferson Hotel to open its doors. Talk about the Jefferson was all over various newspapers raving about the ornate artistic fixtures, rich mahogany furniture, and lavish way in which the hotel was prepared to receive its guests.



It was thought that guests from another city would rate Phoenix based on its hospitality extended by the hotel. The Jefferson prided itself on the level of responsibility and satisfaction to its guests as its way of contributing to the good reputation of Phoenix. As stated in the article, “Helping in her growth, the growth of her industries and her wealth, and her attraction as a place where life is worth living.”(Arizona Republican; May 23, 1915).

Known as one of the fines commercial hotels in the southwest, The Jefferson had everything imaginable. The roof garden being one of the most important aspects of the hotel with a secondary roof. It allowed visitors a breathtaking view of the Salt River valley that stretched for miles with various farms studding the landscape on either side.



The Barrister Building

Why the Barrister Building is important in Downtown Phoenix


Jefferson Hotel Phoenix


Historic preservation can and should be an important aspect of any effort to promote identity, authenticity, and sustainable development.  The conservation and improvement of our existing buildings, including re-use of historic and older buildings, “greening” the existing stock, and reinvestment in historic environments is critically important to establishing our local culture and heritage.

The Barrister building occupies the southeast corner of Central Avenue and Jefferson Street.  Commonly referred to as the “Psycho” Building since Alfred Hitchcock chose it for his famous opening scene in the movie “Pyscho”.  Originally, called the Jefferson Hotel when it was built.  The story of its development gives us an understanding of the people, time, and context of Phoenix in the early 20th Century.


Built in 1915, The Jefferson Hotel was the vision of Salim Ackel, a unique and successful immigrant to the United States.  “His life story also speaks for the business ability and keen mind of Mr. Ackel,”(Arizona Republican; July 15, 1915).  Salum Ackel arrived in Arizona some twenty three years prior to the construction of the hotel.  Mr. Ackel started selling merchandise from a wagon camp to camp.  From that initial position, he was able to get involved in a small grocery store and grow it into a larger emporium.  Mr. Akel also designed jewelry and owned real estate throughout the valley.  “Mr. Ackel’s attributes his business success to two principal factors:  hardwork and strict honesty, and the establishment of first class credit rating. “(Arizona Republican; July 15, 1915)


 Jefferson Hotel Phoenix, AZ


The Jefferson Hotel was at the time the tallest structure in the regional western United States.  “Destined to be the finest furnished and best equipped modern hotel.  The building has six stories with a complete and entire basement, also a well-equipped and beautifully arranged roof garden, and super roof.”  (Arizona Republican; February 23, 1915)  The distinct features of the Barrister Building include the strong horizontal cornice lines at the second floor and at the top of the building.  The building has an understated simplicity with the “tripartite” of a clear base, mid-section, and top expression.  The building fronts Central Avenue.  The perspective of the cornice lines reinforce the main entry and perspective down Central.


 Jefferson Hotel - 1916

The site for The Barrister Building is located just south of the recently completed City Scape development and just west of the basketball arena and the convention center.  Within walking distance of many of the civic and cultural institutions as well as fabulous restaurants and outdoor dining.  The scale of The Barrister Building is critically important.  At six stories it provides an appropriate and much needed pedestrian scaled building with an identifiable entry.

Pomeroy Hotel: Leading The Way

Pomeroy Hotel_01

‘Net Zero’ flagship hotel as urban catalyst for ASU Campus in Tempe, Arizona.
Pomeroy Hotel_02

Circle West Architects seeks to establish an architectural benchmark of innovative design at one of Arizona’s most unique urban opportunities. A forward-thinking approach to planning, programming, and architectural expression is envisioned for the Pomeroy Hotel and Conference Center. The design will serve as a catalyst of sustainability incorporating a ‘net zero’ energy environment.

Pomeroy Hotel_Plan

Great care has been taken to utilize renewable and recyclable materials. The basis of the design is to set a clear identity of purposeful architectural forms appropriately addressing solar orientation, maximizing natural light, while incorporating a dual skin curtain wall concept of insulated, low e glass, along with a secondary skin of perforated metal panels.

Pomeroy Hotel_03

The new hotel and conference center is an urban vision-planning project, which is programmed to achieve a ‘net zero’ environment. The hotel, rising 20 stories with a roof deck pool and amenities, sets out for a modern expression.

The modern building forms and undulating solar sail seek to harness the earth’s energies to provide sustainable cooling and lighting methods for this eco-friendly design concept. To enhance the comfort, key design elements will include dual facades, to supply sufficient natural daylight to the interiors; highly efficient mechanical, electrical, and plumbing systems will be installed; green plants and open space utilising the solar sail will improve local microclimate.

Each floor on the south and north elevation are cantilevered to allow for solar shading and balconies. East and west elevations will accommodate the architectural screening and framework, while the solar sail will shade the main entry and lobby area. The solar sail has a dual purpose of providing shade along with incorporating renewable energy technologies, which will reduce energy consumption and support a ‘net zero’ building environment.

Flash Cube Building

Jul 19, 2012 » Leave a Comment


The Flash Cube Building at Soda Row, in the master planned community of Daybreak is an integral part of a mixed-use pedestrian friendly neighborhood environment. Soda Row features five distinguishable buildings representing various users and serves as the center of neighborhood activity and connectivity. The Flash Cube Building is a three story building with café/retail space at the ground floor with two floors of speculative office space above. The proportions and scale of openings relative to wall surface areas were composed to express movement with varying depths of  translucent glass balconies. The openings and balconies accentuate views to the landscape and mountains beyond with a full glass base to welcome the ground plane.



SouthBank: Urban Rediscovery

Apr 03, 2012 » Leave a Comment

Serving Tempe, Arizona as a distinct vision of an open design strategy to reinforce Tempe’s Bohemian identity, the forward-thinking and inclusive plan is based on fundamental neighborhood planning principles and concepts. 30 acres of mixed-use development, the four neighborhood vision plan integrates residential, office, retail / restaurants, hospitality, and rich public / private open spaces on nine city blocks.

The vision organizes around a series of sequence of spaces and events. The mix of uses are emphasized for each neighborhood with views while embracing Tempe Town Lake. Beyond urban hallmarks of glass, concrete, steel, and modernity, we seek access to new experiences and opportunities for growth.

The landscape architecture and sustainable concepts developed by Circle West Architects focus on social spaces, places to gather, to meet, and with a strong connection to view corridors, shade, and shadow.  They take their identity as much from the surrounding architecture as from the design of the spaces themselves. The landscape and sustainable concepts develop unique visual and symbolic identities by various means, such as indigenous plant palettes, with meaningful associations.

Peter M. Koliopoulos  AIA, SouthBank’s Architect, is a major talent with significant projects throughout the United States. “SouthBank is designed with integrity to be a vital place for people to experience and be inspired.”

The Wolff Den

Dec 19, 2011 » Leave a Comment

Let it snow, let it snow, let it snow. The natural beauty of Sun Valley, Idaho is captured in the recently renovated Wolff Den designed to accommodate two sibling families. The Wolff Den’s attributes of warmth and absorbing daylight are highlighted by the rustic knotty pine flooring, reclaimed wood architectural elements, along with the open “crafted” kitchen. A fresh modern feel is developed with the purposeful collage of materials to accentuate a rich intimacy.



Detailing the Invisible

Nov 28, 2011 » Leave a Comment


Detailing is about connections and how those connections translate into a meaningful expression. Glass as a building material allows for a single material to combine the simplicity of its transparency with its natural characteristic of structural and load bearing behavior. The transparent expression for this single family residence is one of openness. Set in the middle of the natural Sonoran Desert, the landscape and the sky become “living art” for the residents. A wholistic expression of glass is developed by utilizing the 12 inch long structural glass fins to support the 3′-6″ wide by 13′-0″ tall lites of glass. The interior space is planned to host a variety of events both private and public. With the quality of invisibility, natural daylight and moonlight are able to brilliantly amplify the expression.
