Structured Parking
Any above-grade or below-grade, ramp accessible structure capable of accommodating vehicle parking. The multi-level design allows for greater parking densities and increasing land use efficiency.
Putting ‘Structured Parking’ in Context
Overview
Solis Urban Developments, a real estate development firm based in Mexico City, is developing Residencias Reforma, a luxury 25-story condominium tower in the city’s prestigious Reforma district. Given the dense urban location and limited availability of surface parking, the project includes a multi-level structured parking facility located below grade. This structured parking solution allows the development to maximize residential density while still providing residents with secure, on-site parking.
Design and Layout of Structured Parking
The structured parking at Residencias Reforma consists of three underground levels capable of accommodating 120 vehicles. Each level features a ramp-accessible layout with a combination of standard parking spaces, compact spaces, and dedicated areas for electric vehicle (EV) charging stations. The design also incorporates bicycle parking and secured storage lockers.
Unlike surface parking, which requires a large footprint, structured parking allows Solis Urban Developments to use the limited site more efficiently. Instead of dedicating valuable ground-level space to parking, the underground garage maximizes buildable area for residential units, amenities, and landscaped common areas.
Construction and Cost Considerations
Building underground parking introduces unique engineering and construction challenges. Excavating to a depth of three stories in an urban area requires the use of shoring walls to prevent soil collapse. The structural engineer from Ingegneria Firme plays a key role in designing the shoring system, as well as the structural supports for the underground parking decks.
The cost of constructing below-grade structured parking is significantly higher than surface parking due to excavation, waterproofing, and the need for stronger concrete and rebar to support the weight of the building above. For example, while surface parking may cost $50 per square meter, below-grade structured parking can cost up to $500 per square meter. This cost increase is factored into the development pro forma, but the trade-off is justified because of the higher density of sellable condominium units made possible by efficient land use.
Operational and Resident Benefits
The structured parking at Residencias Reforma provides several key benefits for residents and the developer. Residents have access to secure, covered parking with modern amenities like EV charging stations and bicycle storage. The underground parking also reduces visual clutter, as cars are hidden from view, enhancing the aesthetic appeal of the development.
From an investment perspective, the addition of structured parking increases the value of each residential unit. Buyers of high-end condos expect private, on-site parking, especially in a city like Mexico City, where street parking is scarce. This added amenity supports higher sales prices for the units.
Conclusion
In the case of Residencias Reforma, the inclusion of a below-grade structured parking facility enables Solis Urban Developments to maximize land use efficiency while providing essential amenities for future residents. By moving vehicle storage underground, the developer increases the number of sellable units and enhances the appeal of the development. Although structured parking increases construction costs, the investment is recaptured through higher unit prices and the competitive advantage of offering secure, modern parking in a dense urban environment.
