Tantamount to the feasibility of the conversion, new MEP systems had to occupy minimal space and be housed within the existing structure or concealed from view, with no modifications to the façade. With no roof space for air conditioning heat rejection, suitable space had to be found without violating landmark regulations.

Focused on turning the Tower’s restricted architecture into an asset, the feasibility study’s innovative solutions included:

• Strategically locating new bathroom and kitchen air extract systems within the building, with discharge away from view,
• Placing cooling towers within air discharge plenums, allowing incorporation of a heat rejection system while also creating a heat recovery system that provides important environmental and economic advantages
• Designing new electrical and steam services to fit within the cramped confines of the Tower’s basement
• Replacing one of three gravity-fed water tanks with a constant pressure pumping system in the basement

By demonstrating the economic feasibility of converting an architectural gem for residential use, this study provides a model for converting other landmark buildings with similar challenges—buildings which, if left untouched, remain vacant. In cities where residential space is at a premium, this type of solution is vital to smart development.
