Contact Us Custom Hardware Creates Design Continuum The Four Seasons Hotel and Private Residences, One Dalton Street, Boston adds a modern, triangular silhouette to the city skyline. Project designers added a distinctive touch to the interior aesthetics by working with ASSA ABLOY to create custom door hardware that matched the building's triangular exterior. The project design team worked with ASSA ABLOY design engineers to develop door levers and pulls that enabled an aesthetic continnum to be carried through the facility. ASSA ABLOY design engineers worked with the architects to create an initial lever design that was rendered on a 3D printer, allowing for easy tweaks. The selected style was then created in a base metal and plated for the client to review. Then a final design was produced to exact specifications. This lever is installed on Yale hardware used on all secondary doorways and the VingCard locks found on all hotel room/residence entry doors.
