Stantec leaders share eight methods to method artistic adaptive reuse in central enterprise districts.
Downtown enterprise districts in North America not get the 9-to-5 visitors they as soon as did. The emergence of hybrid and distant work, ageing 20th century workplace constructing inventory, and relocation of beforehand stalwart tenants to newer confines has resulted in an exercise drain in central enterprise districts. Many older workplace buildings are experiencing declining occupancy. This leaves constructing homeowners with the query of what to do with an extra of accessible house — and metropolis planners and builders in search of options to invigorate these districts.
In the meantime, housing affordability is a persistent subject, particularly in city cores. There may be, nonetheless, a preferred need to expertise genuine locations with historical past and tradition that these districts can faucet into.
Can we repurpose these buildings to serve the town’s altering wants? Below the fitting situations, sure. The reply lies in considerate and artistic adaptive reuse.
In Chicago, we’re designing the 740,000-square-foot Monroe Resort and Residences within the former BMO Harris Financial institution headquarters, a 24-story landmark within the coronary heart of the LaSalle Road Historic District. Our current work in Chicago’s Loop exemplifies the opportunity of design for reworking downtowns. And in Columbus, Ohio, we’ve got designed a combined occupancy conversion of a 24-story modernist workplace tower at 155 E Broad Road known as Preston Centre.
With these experiences in thoughts, listed below are eight finest practices we promote for taking over downtown constructing repositioning.
Embrace authenticity.
The authenticity of historic buildings is one thing that you could’t replicate. You’ll be able to’t construct a historic constructing. For the Monroe Resort and Residences, we got two historic towers to work with—the classical, authentic 1910 Harris Financial institution & Belief constructing and a 1958 metal stainless-steel and glass addition within the type of Mies Van Der Rohe. Our design wanted to have fun these buildings and join the brand new makes use of of the buildings to the general public’s ardour for Chicago’s architectural heritage. The result’s a design that preserves and celebrates the facades of the towers, whereas incorporating up to date options and appropriate facilities. New programming accents the constructing’s engaging heritage. The Monroe Membership, previously a mid-century non-public membership, might be reimagined on the penthouse flooring and lodge visitors will enter by way of the Harris Financial institution’s spectacular, century-old foyer.
In Columbus, the consumer’s admiration for 1970’s tower’s Italian travertine-cladding and fervour for the town itself impressed the workplace tower reuse venture. The consumer and crew prioritized the constructing’s architectural character and presence in Columbus’ city core. Its façade was to not be altered or penetrated. And we evaluated venture updates on how they celebrated the constructing and fostered a connection to the road stage. Preston Centre will embody 105 residential models, 170,000 sq. ft of workplace house, plus ground-floor retail. Neighboring the historic Trinity Episcopal Church, this mixed-used venture is meant to convey vibrancy to the town’s downtown.
Pivot to new makes use of that meet demand.
North American cities are struggling to fulfill the demand for reasonably priced housing. And downtown staff usually face lengthy commutes from the locations they will afford. Cities are responding. Austin, Texas plans to create 60,000 models of housing for these making lower than 80% of the median household earnings. Our authentic concept for the previous monetary providers workplace constructing in Chicago was to mix new residential flooring with renovated workplace areas in a multipurpose constructing. However the market situations confirmed our consumer that a greater match could be a residential and lodge mixture.
Reasonably priced flats on or close to LaSalle inside Chicago’s Loop are scarce. Designing for the entire constructing allowed us extra freedom to method design for the mixed towers. We designed the Monroe Resort and Residences with 345 flats on its higher flooring, of which 105 flats might be put aside as reasonably priced for tenants with earnings at a mean of 60% of the world median. The Monroe affords downtown staff a brief commute and instant entry to a walkable city way of life.
However the constructing is just too huge to be 100% residential. With our consumer’s expertise in hospitality, a lodge emerged as the most suitable choice for reuse of the decrease portion of the constructing. An roughly 300-room lodge will occupy the primary 11 flooring with a floor stage tremendous eating restaurant plus a rooftop bar with swimming pool.
Revitalize downtown areas.
Workplace vacancies within the U.S. reached a record-breaking 19.6% on the finish of 2023, in keeping with Moody’s Analytics. The continued decline in workplace house occupancy initiated by “flight to high quality,” and accelerated by the pandemic and superior by earn a living from home, has left many older CBDs with shuttering eating places and struggling retail.
Changing ageing, run-down workplace buildings to residential flats affords new life to those districts. And the financial ripple results of infusing CBDs with new residents ought to prolong past the 9-to-5 workday, a possible boon to retail and providers and downtown economies usually.
Ideally, the larger residential density might be adopted by public facilities (colleges and parks) and industrial ones (grocery shops). This enables individuals to dwell, work, and ultimately play in the identical neighborhood.
For a lot of downtowns, changing surplus workplace house to fulfill the necessity for residential flats in enterprise districts by way of adaptive reuse is a pure match. It’s catching on. The variety of office-to-apartment conversions in main cities has risen from 12,100 in 2021 to over 55,000 scheduled for this 12 months, in keeping with BisNow.
Flip bodily challenges into alternatives.
We all know from expertise that surprises typically lurk inside older buildings—of their supplies, out of date methods, and inefficient layouts. However additionally they might supply us house to program and create the dynamic, mixed-use environments that right now’s cities want.On the Monroe Resort and Residences, the reimagined constructing will get upgraded, high-efficiency methods for cooling and heating. These new compact methods will depart us with superfluous mechanical areas that we will repurpose as facilities. For instance, we’re reworking the previous mechanical penthouse from the financial institution headquarters right into a lounge with an out of doors deck and pool for lodge visitors. And we repurposed two whole former mechanical flooring for flats. Our design resolution for the Chicago conversion additionally takes benefit of three ranges beneath the constructing for adaptive reuse with 130 valet parking areas for residents and visitors. Elsewhere, the constructing’s character affords aesthetic alternatives in reuse that might be price prohibitive in a brand new constructing. The gorgeous midcentury constructing affords full-height glass and spectacular views for residences.
Be daring and visionary.
Adaptive reuse designs ought to do greater than meet primary market necessities, it ought to encourage.
In Columbus, our collaboration with the consumer resulted in a design which reaches out to the streetscape with a landscaped plaza that includes a Japanese-inspired sunken backyard, waterfall, and pond that might be open to the general public every day. The brand new mixed-use constructing will characteristic a glass-enclosed tremendous eating vacation spot. These particulars are designed to reinforce the character of the neighborhood and produce new dynamism to the town’s downtown. Preston Centre will ultimately hook up with a large-scale redevelopment of downtown Columbus that features a park impressed by New York’s Excessive Line.
All through the interview and design course of for the Monroe venture, the consumer responded to the power of our imaginative and prescient for the constructing and the district itself. We envisioned a constructing the place life occurs, a spot for dwell/work/play, in a district that has all the weather of a 24-hour metropolis. Our design prompts the rooftop deck and atrium areas as new locations for the general public.
One problem was reconciling the constructing’s earlier use with its new function. Whereas workplace interiors don’t require home windows in each room, residential models do—for mild and air flow. We created a courtyard throughout the constructing to take care of the massive flooring plates and produce pure mild and air flow to the middle of the constructing. Our design carves a 60×70-foot courtyard, 19 tales tall, with a full-height characteristic wall into the constructing with out altering street-facing facades. The brand new flats and lodge rooms have entry to recent air and daylight and views into the verdant inside courtyard.
Choose the fitting constructing.
Constructing repositioning tasks are a fancy endeavor in right now’s atmosphere. To succeed, a venture should make monetary sense and supply house that meets market wants in an acceptable location. It should supply return on funding. Some buildings make higher candidates than others, normally these the place little modification is required. Search for buildings with home windows on 4 sides, smaller manageable flooring plates, properly positioned stairs and elevators, and façades that received’t require vital renovation. For older buildings, historic landmark standing can present tax credit. And the architectural magnificence and character of a historic constructing has a attraction that’s tough to copy.
For the Monroe Resort and Residences, we needed to design flats with the size and facilities that had been acceptable to Chicago’s residential market. We laid out the residential flooring effectively with models sized so that they may very well be priced attractively.
Suburban workplace properties are harassed as properly, usually vacated, or left with extraordinarily low occupancy. Sadly, these properties don’t have the inherent walkability, neighborhood facilities and entry to public transit present in CBDs. Thus, their worth for conversion to residential hardly ever makes monetary sense.
Decrease carbon emissions.
By its nature, a large-scale constructing reuse venture has fewer related carbon emissions than a traditional new constructing with demolition. Moreover, CBDs have glorious entry to public transit, lowering the necessity for parking, and creating extra housing inside strolling distance of areas with the best density of jobs. The walkable nature of those conversions reduces emissions, too.
On the Monroe Resort and Residences, we’re saving an enormous amount of the embodied carbon spent on the supplies and development for the 2 towers, of their glass, their metal, their masonry, and their foundations. We didn’t take the venture’s sustainability with no consideration. Each time potential, we continued that low carbon method all through the design for reuse.
Embrace incentives for adaptive reuse.
The numerous prices related to most conversion tasks necessitate incentives and/or subsidies to assist builders pencil out their proformas.
Few North American cities are incentivizing the workplace conversion. Calgary’s Downtown Calgary Growth Incentive Program provided grants of as much as $15 million per venture for workplace to residential, lodge, college and performing arts middle conversions.
On the Monroe Residences, we assisted the consumer in looking for monetary incentives the Metropolis of Chicago made obtainable to advertise artistic conversion of workplace buildings by way of its LaSalle Road Reimagined program. This system affords financing to qualifying residential tasks consisting of 30% reasonably priced models. Some cities are resorting to fast-track entitlements and different help hoping to pave a neater path for builders.
In mature downtown areas, zoning and entitlements can current prolonged and difficult obstacles for reuse tasks. New York Metropolis, for instance, has age restrictions on buildings altering use from workplace to residential. Cities like Chicago, nonetheless, have inherently versatile zoning codes based mostly on excessive density mixed-use to hurry approval.
Adaptive reuse of an ageing workplace constructing is a fragile balancing act. If we will design them for brand spanking new functions that resonate with {the marketplace}, we may give these necessary locations a second life. Twentieth century buildings can meaningfully contribute to the revitalization of our downtown neighborhoods.
