The massing of the newly constructed tower was carved to form a series of alternating glass and masonry volumes, creating vertical strips of material that are meant to relate to the linear landscaping of the Jessie Square plaza on which the tower fronts. The tower's vertical masonry was also organized to visually connect with the strong vertical expressions of brick and terracotta of the Aronson Building next door. Lead architect Glenn Rescalvo’s goal was to create a Park Avenue-like building inspired by the nearby Pacific Bell Building and showcasing impeccable craftsmanship.

“This project beautifully showcases the complex interplay between two contrasting buildings – the historic Aronson Building finished in a darker color palette adjoined by the new tower, which showcases lighter tones,” said Rescalvo, partner at Handel Architects. “Our goal was to create a legacy building that wasn’t just all glass – instead, we utilized undulating stone on the façade to create a sense of movement and make the project standout on the San Francisco skyline.”

Ten stories tall, the Aronson was constructed in 1903 in the Chicago School style and was one of the only buildings to survive the city’s Great Earthquake of 1906. According to Elisa Skaggs, AIA, associate principal with Page & Turnbull, the firm's architects and conservators were focused on preserving the Aronson Building’s noteworthy, elaborate facade, which inspired the vertical masonry Handel Architects included in its design for the adjacent tower. Page & Turnbull also oversaw the stabilization of the approximately 120,000-square-foot structure to make it fit for new uses and ensure continued long life.

The project is impressive from the moment of arrival. A stately porte-cochère greets residents and guests, finished in fine luxury materials. Herringbone pavers line the driveway surrounded by a soothing water feature and neatly trimmed hedges to create a feeling of seclusion and privacy. The lobby features a grand fireplace covered in striking black and white marble alongside the welcome desk, also finished in the same material. The property’s elevator banks showcase personality as well, with intricate marble flooring and patterns wrapping the walls.

The project’s 146 residences are uniquely spacious and done in the pre-war style, with square footage spanning up to 5,000 square feet. Sized like grand-estate homes, there are only four residences per floor, and only three in the Aronson Building, ensuring greater privacy. The interior planning of the residences has been guided by a series of design principles, including a dramatic entryway; grand corner living rooms with at least two walls of floor-to-ceiling glass; defined dining areas; adjacent yet private informal family areas; large kitchens positioned to serve as the heart of each home; master bedrooms with breath-taking views; large, light-filled master baths; in-home offices and guest bedrooms with in-suite baths.

With attention to personalization, kitchens have been configured so that they can be open to the living areas or enclosed, based on the buyer's preference. Master baths are five-piece baths featuring enclosed glass showers, free-standing tubs, two lavatories and a toilet fixture. Top-of-the-line appliances, cabinetry and stone countertops are included throughout each home. Buyers of the Penthouse Collection, the project’s portfolio of penthouse level offerings, have the option to purchase a “shell home” that can accommodate design specifications per their wishes.

The famed London-born cabinetry designer Christopher Peacock, has created The Penthouse Collection as an exclusive cabinetry collection for the penthouse homes, including meticulously crafted kitchen, master bath, and dressing room cabinetry. Peacock’s creations can be found in many of the world’s most stunning private estates and his bespoke offerings for The Penthouse Collection mark his first collaboration with a luxury high-rise in San Francisco.

Dressing rooms will be a distinct design focus of The Penthouse Collection. These spaces are not just walk-in closets, but rather bespoke spaces for dressing that are perfectly tailored to each buyer’s personal preferences. Cabinetry offerings in the dressing rooms will include transitional and contemporary stylings that will be fitted with custom hardware created by Peacock.

Appointed with the finest finishes and the latest technology, the amenity floor “Club” on the building’s fifth level provides a convivial indoor/outdoor gathering place where residents can socialize. Features include a state-of-the-art fitness center designed by celebrity trainer and fitness guru Harley Pasternak, a lounge with a tendered full bar, private dining, and a landscaped outdoor terrace with welcoming firepits. The Club also includes a meticulously appointed game room that features a custom-designed media wall.

The project is the latest in an exclusive collection of Four Seasons standalone Private Residences, independently managed by Four Seasons staff and offering residents an unparalleled level of premier amenities and services. Four Seasons debuted its standalone Private Residences at Twenty Grosvenor Square in London, followed by projects in Los Angeles, Marrakech, and now San Francisco.
