Upper East Side Townhouse

A reconstructed Landmarked Upper East Side townhouse.

Originally built as a single family home in 1879, the landmarked Neo-Grec brownstone had since been divided into 17 apartments with a sagging and badly degraded structure. MKCA reconstructed the building, carefully inserting a new 9600 sf steel and concrete structure, expanding the building’s footprint, and creating opportunities for light, air, and circulation to enliven the interior and exterior. An elevator and sculptural new stairs were added, along with generous floor openings and glazed double height spaces that emphasize the building’s grand proportions and create visual and spatial connections between floors.

The interplay between technology and artistry is an organizing principle behind the design of the project, from architecture to interiors to landscape design. One of the richest challenges was to to bond the desire for a contemporary, forward looking residence to the history of the building and its context in a meaningful way. This is accomplished primarily through an exceptional attention to craft, augmented by digital methods for design, coordination, and collaboration. The machine-produced decoration and crisp, incised ornamental surfaces that are characteristic of the Neo-Grec style were projected forward to a contemporary context, informing current and forward-looking processes of making like computer controlled milling and other contemporary manufacturing methods.

Throughout the house, works of design by emerging and independent American designers and studios is integrated with significant works of modernist design from Italy, Scandinavia, and the United States. Much of the contemporary furniture was custom designed for the house primarily through designer commissions, including a number of custom pieces by MKCA.  MKCA is solely responsible for the project’s architecture as well its interior design.

High-precision digital and hand craft are a predominant feature throughout the house. A delicately carved wood ceiling in the entry vestibule takes cues from the carved egg and dart moldings of the original facade, scaled and shaped into billowing and converging surfaces. A braided railing of bronze, steel, and walnut is integrated into faceted white oak and travertine stair treads. A luminous formed white oak and glass screen separates private dressing space from the main stair on the master bedroom level.

Numerous plantings and exterior spaces were also incorporated into the design of the building and developed in collaboration with Local Office Landscape Architecture and conservation botanists at SUNY. An entirely glazed rooftop addition opens onto a terrace with clifftop trees and grasses. A primordial palette of indigenous woodland grasses, ferns, and mosses creep up the rear stairs from the garden below, and a vertical garden, also fully integrated into the building as part of the terra cotta rear facade is host to a series of rare plant species from the Hudson Valley, some of which are endangered due to climate change. The facade is comprised of custom formed and glazed terra cotta elements with an undulating texture. MKCA worked with the manufacturer to develop a production method for the terra cotta that is at once fully bespoke and artisanal in its nature but efficiently manufactured and installed.
