Cost Estimate to
Build the City

The cost to build the City is the same as what is spent on the chronic homeless over 8 months.


These conceptual estimates are calculated a variety of ways: using comparables of previous projects (a.k.a. analogous estimates), using various online resources to obtain historical cost data (a.k.a. parametric estimates), and in some cases, compiling data from various sources to create an educated guesstimate.

The best efforts were made to achieve accurate cost estimates for each item; however, two additional estimates are included as well. These are either simple multipliers based on Cost Estimate A; or have modifications in the price, which are detailed upon hovering over the cost number.

The following have been roughly calculated and included in a catch-all category. These items either lack available details for calculations or require more significant experience in estimations:

  • Infrastructure
  • Furniture, desks, office supplies, security equipment, vehicles
  • Train tracks
  • Factory equipment
  • Vehicles
  • Land
  • and more

Things to keep in mind when reviewing the estimates:

  • These costs are not exact and are intended only as a preliminary guide for possible project cost. The actual project cost may vary greatly depending on many factors.
  • Cost estimates are based on pricing and comps with 2019 dollars, and no adjustments for the cost of inflation have been made.
  • Although potential plots of land have been identified, along with “for sale” pricing and comparables, land cost is not included in this overall estimate.
  • Unless otherwise noted, all price per square feet is obtained from construction estimating tool.
  • Numbers are rounded up when needed.

  • Citizens Again does not make any warranty or guarantee as to the accuracy, correctness, value, sufficiency or completeness of the data or resulting project cost estimates; nor, in any guarantees, all buildings, structures, or amenities will be built to the listed specifications, or at all.

Cost estimates have one of three visual indicators to identify cost accuracy:

Accurate Estimate: Price estimate was obtained by finding similar completed projects posted online, or from companies that provide posted rates for projects.

Close Estimate: Pricing obtained by using online estimating tools that average project costs by pulling averages of materials and labor costs, according to specific geographical regions.

(No indicator): No indicator is used if no reliable pricing was found. Pricing was still calculated by analyzing comparables to similar projects, cost and sizing of materials, etc.

Cost Estimates (v 1.0)

The following is the first conceptual estimate to begin the process of the initial feasibility process of the project, all based in 2019 rates.

Facility Quantity Total Sq. Footage Cost Estimate
Cost Estimate
Cost Estimate
Dorm Buildings
Residents live in the dorms, which consist of sleeping rooms, and communal showers and bathrooms. There will be 16 dorm buildings, each consisting of 16 floors each, 5 wings per floor, and 40 rooms per wing. That equates to 3,200 rooms per building (40 rooms x 5 wings x 16 floors).
Cost Basis
After detailed review and calculations from preliminary dorm building plans, it's estimated that each floor (including 5 wings per floor, plus the middle round area which contains elevators and stairs), will be 26,711 sq ft. With 16 floors, that equates to 427,376 sq ft per building. 16 buildings = 6,838,000 sq ft total. puts 8-24 story apartment buildings with this sq footage at $90 sq ft; and 11-20 story office buildings, at $135 sq ft. (which is 50% more than apartments). So estimate A will be $90 sq ft; B will be a 1.3x multiplier of A; and C will be $135 sq ft.

(427,000 sf each)
$615.4M $800M (1.3x) $923.1M (1.5x)
Cafeteria & Services
Each of the 4 neighborhoods will have their own cafeteria and kitchen. Each building will be 3 stories, consisting of a kitchen basement, first-floor serving and seating, and top floor open space.
Cost Basis
With such a large population, staggered dining shifts will be assigned to citizens.
To figure out needed seating, square footage, and building cost, a variety of research and intertwined calculations are performed.
First of what's needed is to estimate the time per table seat. School Nutrition Association summarized three studies sponsored by the National Food Service Management Institute (NFSMI) to measure the average time required by K-12 students to consume lunch in school cafeterias. The report concluded that the average time for high-school students to consume lunch (eating at the table) was between 7 and 10 minutes, and non-eating activities at the table ranged from 3 to 26 minutes. Considering the stated factors in this report in relation to this project, it's estimated the social time at the table to be approximately 5 minutes. This brings the time at the table (eating and non-eating) to 12 – 15 minutes. So to estimate cafeteria size, the 15-minute range will be used.
Next is to calculate the number of required seats per each cafeteria. A 12' table can seat 12 people (6 per side). In the mockup images, the cafeteria has two 12' tables end to end (so this table unit is 24' long, and can sit 24 people), with 5' walking paths. The mockup has 15 rows by 4 columns of table units (24' table that sits 24 people)… so that's a total of 15 rows x 4 columns of table units that sits 24 people = 15 x 4 x 24 = 1,440 seats.
Then to estimate the duration of the meal period, assume a maximum population of 150,000 people, 4 hours of staggered assigned meal slots (citizens are assigned which time to arrive for their meal) per meal period (breakfast, lunch, dinner) in 4 cafeteria buildings (1 in each neighborhood), each with 2 rooms for serving and seating (a left side cafeteria and right side), with at least 10 serving stations in each room, with 1,440 seats in each left/right cafeteria. That would equate to a possible 179,200 meals served per meal period. Sack lunches would be made available for citizens working in industry jobs. Also, office and industry jobs may have their own cafeterias for workers as well.
The kitchen will be in the basement and food will be brought up through dumbwaiters to the serving stations.
The building's top floor will have same square footage as below, and will be a place for citizens to lounge, play board games, bingo, read, socialize, etc.
In addition, the full-service laundry facilities will be located in the basement level of each cafeteria building.
With those numbers, the building square footage can be calculated. The square footage for each table unit is 24' long x 38" wide (including seat area), plus the walking area perimeter of 2.5' (this creates a 5' walking perimeter around all table units) so that's 26.5' x 5.7' = 151 sq ft per table unit x 60 table units = 9,060 sq ft. If half the cafeteria footprint is set for seating, and the other half is for serving stations, waiting in line, restrooms, hand washing stations, bus stations, etc., then that equates to a cafeteria footprint of 18,120 sq ft. x 2 sides = 36,240 sq ft. This equates to a total of 72,480 sq ft for each 4-level cafeteria in the 4 neighborhoods.
For price estimates, didn't have Cafeteria option, so Restaurant was chosen; with price per square foot at $157, resulting in $8.5M (includes the 2 levels of cafeteria and basement kitchen). In addition, there will be a top floor with the same square footage, for citizens to lounge, play board games, bingo, read, socialize, etc. Price per square foot will be estimated at $100 per sq ft, that's $1.8M additional. This equates to a total of $10.3M for each cafeteria building.

Citizen Services
Various services to assist citizens with issues they have while living in the city and for preparing to leave the city.
Cost Basis
Assuming it's a 2 story building, with a 43,500 sq ft footprint, that equates to 87,000 sq ft, and at $91 sq ft (Office 1-3 Story rate from, that adds up to $8M per building.

Healthcare & Education
Fully-equipped, 3 story 285 bed Narayana Health/HCCI style hospital.
Cost Basis
Assuming a maximum city population of 150,000, and using California's average number of 1.9 hospital beds per 1,000 people, equates to a hospital with 285 beds. To estimate the hospital building gross square feet (BGSF) per bed, the hospital would be modeled after the Healthcare City Cayman Islands (HCCI) which is owned, designed, and built by Narayana Health. HCCI BGSF is 1,029, but is single story; so an additional 15% of square feet would be added because of extra footage for multistory, totaling 1,183 BGSF. This is not much different than US community hospitals built 30 years ago, which were as low as 1,300 BGSF (new hospitals today are as much as 2,800 BGSF per bed). With 285 beds multiplied by 1,183 sq ft equates to 337,155 sq ft. Using hospital construction costs of $590 per square foot , equates to a total of $199M. Learn more from Harvard Business Review and Commonwealth Fund about how US hospitals have become so much more expensive, and how Narayana Health achieves high-quality hospital care, at a lower price (95% cheaper than US prices).

Health Services
The Health Services Buildings comprises of various healthcare providers, including medical offices (exams and ailments), optometry (eye tests, eye health, receive glasses), orthodontists (all dental care, including exams, teeth cleaning, root canals, fillings, and more), mental health & therapy (psychiatrists, therapists, family and group therapy), and personal care services (barbershop, hair salon, nails, and more).
Cost Basis
Each healthcare category will have its own floor, for a total of 5 floors dedicated to healthcare services. In addition, the building will have a floor dedicated to personnel, for cafeteria, lounge, restrooms, etc.; and another floor for medical labs, materials storage, etc. Building will have a 43,500 sq ft footprint, so 7 floors equates to a total of 304,500 sq ft. Price per square foot is estimated using Medical Office median average, is $104, and to simply, this will be used for entire building.

(304,500 sf each)
($31.7M each)
$82.4M (1.3x) $95.1M (1.5x)
Education Building
Staff in the Educational Building will offer educational services, training, and classes on a variety of topics ranging from GED certificate programs, arts & crafts programs, music classes, industry-specific job-training classes, and more.
Cost Basis
To estimate the size of the building, a variety of assumptions have been made. If the building is open 7 days per week, and open from 9 am to 9 pm, that provides 84 hours per week it's open. According to School Planning & Management, the median high school provides 180 square feet per student. In other words, while in the building, a single student consumes 180 square ft while in the building. Assuming on average a citizen may use the Educational Building 3 times a week, on average of 3 hours each time, that's a total of 9 hours out of the available 84 usable hours of the building; this equates to 9.34 students will use a single block of 180 square ft in a week's time. So if the Educational Building is 1 story, and has a footprint of 87,000 sq ft, then if we divide that by 180 square ft, it equates to a maximum of 483 students in the building at one time. So if there is a 9.34 cycle of students during the week, that equates to 4,511 students for a single floor.
If the city has a 100,000 population, and it's estimated that 25% may want to use educational services during the week, that equates to 25,000 students per week. With 2 Educational Buildings in the city, that means the building should accommodate 12,500 people in a given week. So dividing the need of 12,500 by 4,511 students per single floor = 2.77 floors. Let's round up to 4 floors, as population might be higher, and to ensure enough room for classes.
To accommodate large audience, venues in the city such as Event Venue, Stadium (which can be subdivided), or in outdoor space in parks will also be used.
So a building with 4 floors with 87,000 sq ft per floor will be a total of 348,000 sq ft. Two buildings will be a total of 696,000 sq ft. Using's College Classroom rate of $114 per square foot, equates to $38.6M per building.

Bowling Alley
50 bowling lanes, and large spectator viewing area.
Cost Basis
Bowling industry typically recommends a population density of 2,000 people per lane. At 100k population average, that's 50 lanes. On average, it takes 1 person 15 minutes to play one game. At a maximum, that lane can cycle through 4 people per hour. Multiply that by 50 lanes = 200 people per hour x 16 hours (the number of hours it's open each day) = 3,200 people per day x 7 days = 22,400 people can bowl 1 game per week. For square footage, an existing 50 lane bowling alley was used for general sizing estimates, but will also have spectator seating. Average cost to build is $100k per lane, so that equates to $5M.

Social Hall
The 4 story Social Hall is a place for citizens to gather, socialize, and enjoy numerous venues for DJ music, live music, comedy, and other various acts, as well as socialize in a large area to talk, play cards or board games, read, and more.
Cost Basis
The building will be 4 stories with a 43,500 sq ft footprint. 3 levels will dedicated to entertainment venues, and one floor dedicated to an open space to socialize.
If each entertainment floor averages 3 venues, that's 14,500 sq ft per venue. Assuming 75% of each space is usable space for citizens, which equates to 10,875 sq ft. Using the space calculator and choosing the reception layout that estimates 1,088 people per venue, equating to 3,264 people per floor. If 3 floors have similar venues and usage, that adds up to 9,792 people. For the open space social floor, if the Banquet 6' option in the space calculator is used, that could be a maximum of 3,619 for that floor. In all, the entire building could hold over 13,000 citizens.
Pricing this would use the Social Club per square foot of $165 for entire building.

Storage Lockers
The city will securely store all citizen possessions on-site in storage lockers, available when/if citizens choose to leave the City.
Cost Basis
The facility will be 3 stories tall with double or triple stacking lockers on all levels. The building footprint will be approximately 112,500 required for 3 stories of lockers and walking paths, with an additional 5% for additional vehicle paths, etc., for a total estimated footprint of 118,000 square feet (with 3 stories, this gives approximately 337,500 sq ft for usable locker and pathway space). Using Warehouse pricing of $52 per square foot for the footprint, that equates to $6.1M. Add an additional $15 per square foot for 225,000 sq ft of space on the 2nd and 3rd level mezzanines, equating to $3.4M. And add $1.5M for lockers, to bring overall total to $11M.

Office Towers
The city will have six 7-story office buildings where capable and willing citizens can perform outsourced work for other companies. Jobs will include call center and other back-office work.
Cost Basis
All buildings will have a 43,500 sq ft footprint/per floor, for a total of 304,500 sq ft per building. Each building will have an entire floor dedicated to a cafeteria, lounge, and other non-productive areas.
Building size has been determined by the anticipated type of work and based on industry recommendations of spacing requirements of 125 square feet per person.
Five buildings will have 6 floors of workers, which equates to 261,000 of office space per building. With a maximum occupancy, that could be as much as 2,088 people per building at a given time.
One building will have one floor dedicated to a visitor center for citizens; resulting in that building having 5 floors of workers, which equates to 217,500 of office space. With a maximum occupancy, that could be as much as 1,740 people in that building at a given time.
According to, buildings of this size are priced at $92 per square foot, which equates to $28M per building. 6 buildings total $168M.

Dog Kennel and Park
Housing and park for citizens' dogs they bring with them to the city.
Cost Basis
Estimating 5% of the chronic street homeless population (assume 100k people) have dogs and choose to bring them, then capacity for 5,000 dogs would be needed. Kennel requirements, according to is approximately 67 sq ft for each dog sleeping area, and about $12 per square foot for build out. With 5,000 dogs, that equates to 335,000 sq ft., plus additional 43k indoor play space. The multi-story facility would be more similar to a warehouse, so $20 per sq ft would be more apt. And an additional $500k for outdoor play area with pond and park-like amenities.

Hotel for Visitors
The city will have an on-site hotel, outside of the city, and will offer complimentary stay for visiting family members and friends of the citizens; as well as complimentary lodging for all visiting entertainers for the city's venues, visiting athletes for the sports arena, and for traveling interviewees for open city positions.
Cost Basis
It's estimated to have a need for 400 rooms. Using calculations from, a 400 room hotel would equate to about 167,000 sq ft. With a 43,500 sq ft footprint, that would be about 4 stories.
Using construction pricing from research report from Cushman & Wakefield, using data for Upper Midscale pay rate without land costs, puts the price per square foot at about $163, for a total cost of $27.2M.

Parking Lot
Approximately 3,000 parking spaces for staff and visitors are needed. They will be in close proximately to their worksite, such as Admin building, hospital, factories, etc. Parking spaces will be under the canopy of Solar panels (solar carports). These panels are priced separately under Solar Farm.
Cost Basis
Preliminary staffing calculations indicate the city could have as many as 3,500 on-site workers. Not taking into consideration of public transportation or carpooling, and based on assumptions of the number of staff during peak working hours, it's estimated about 2,700 parking spots would be needed. Adding an extra 300 spaces for visitors brings the estimate to 3,000 total parking spaces.
Calculations indicate about 22.5 acres would be needed.

On-site apartments will be provided for free or subsidized cost, for city interns and employees. The majority of occupants will be for therapists-in-training for their service hours. Cafeteria services may be provided.
Cost Basis
If apartments averaged 1,000 square feet (some will be 1 bedrooms for single occupants; some will be multiple bedrooms for families), with 300 apartments, priced at $76.80 per square foot according to (that equates to $76,800 per apartment), that totals $23M.

Visitor Center
Since visitors are not allowed in the city, a large indoor space (approximately 21.500 sq ft) and outdoor space (2-acre outdoor park shared with the office buildings) are provided to allow citizens to see visiting family members and friends.
The visitor center will be located in 1/2 of the bottom floor of one office building, so no additional costs here.

Streets and Sidewalks
Although the city will have very little motorized vehicle traffic, it is vital to give enough room for bicycles, emergency vehicles, possible mass transit vehicles, possible supply or maintenance vehicles, and large amounts of pedestrians walking to their destination. So it will have 2 lanes in each direction, and 30' wide sidewalks.
Cost Basis
If we used San Francisco's Market Street, next to Montgomery Street as a model to calculate the streets inside the city, we would have two lanes of traffic in each direction (each lane being a recommended 12' wide), and have 30' wide sidewalks on each side to provide ample walking space, the total street/sidewalk width would be 108' wide. The streets in the factories, as well as outside the walls will not have sidewalks, so assume two roads in each direction with no sidewalks, for a total width of 48' wide. Based on the current layout of the city, there are approximately 26,416 linear feet of roads within the city, and 15,184 on the city's close perimeter and for factories. According to, a thickness of 6" would be appropriate for roads for this city's use. So calculating pricing for the city streets, with a street/sidewalk total width of 108' wide at 6" thick, that equates to 54 cubic linear feet across or 2 cubic yards per linear foot. If we assume concrete materials cost $90 per cubic yard that equates to $180 per linear foot for street/sidewalk combo. So with 26,416 linear feet, that's $4.8 million in materials cost Outside city, road width would be 48' wide (4 lanes) at 6" thick that equates to 24 cubic linear feet across, or .89 cubic yards, that equates to about $80 per linear foot. So with 15,184 linear feet, that's $1.2 million. If we assume materials are only 25% of the cost of the street ($6 million in concrete), then labor and other items would total $24 million, or $577 per linear foot for all 41,600 linear feet of streets and sidewalks in the city and perimeter.

Wall & Fencing
Wall around city, as well as fence around entire property.
Cost Basis
Based on current layout of the city, approximately 14,500 linear feet of wall would be needed around the city. This would probably be a reinforced concrete wall or concrete blocks, similar to sound walls used on highways. In addition, there would be a fence around entire property to secure solar panels, parking garages, factories, etc.
For the 14,500 foot long city wall, if we can assume costs similar to California's Department of Transportation stated costs for sound walls of $450 per lineal foot it would total to about $6.6M.
For fence around property, if the property was a total of 700 acres (approximately 30 acres by 23 acres), that would be a total of 22,200 feet of perimeter fencing needed. If we assume the fencing and installation is approximately $29 per linear foot that equates to about $643,000. Total costs for wall and fence would be $7.2M.

Solar Farm
A solar farm around the city will provide green energy for the city and preserve land for future expansion.
Cost Basis
With the current map layout, the city and factories currently consume 345 square acres. If a 3 acre perimeter around the city was added, that would equate to approximately 600 square acres. If space from parking, hotel, apartments, roads, as well as the entire city were deducted, that would equate to approximately 235 acres of open space.
If 80% of the entire 235 acres were used for solar panels, that would be 188 acres, and estimating about 7 acres per megawatt, 188 acres could potentially produce 30 megawatts, which theoretically is enough energy for 6,000 households (its unknown the energy needs for the city, so this is just for informational purposes). Solar farms of this size cost about $1 million per 1 megawatt, so this installation would cost approximately $30 million.
