The Ultimum Multilevel range stands at the apex of the Zakuna entrance door programme. These are doors designed for those who do not compromise — four-time winners at the German Design Awards, the Ultimum collection is recognised across southern England as a benchmark for front door design, engineering, and material quality.
Across 20 designs in the Multilevel series, the range explores some of the most visually complex and architecturally resolved entrance door compositions available anywhere, including multi-plane door leaves with contrasting material zones, integrated sidelight and overhead glazing systems, and doors that incorporate digital surface patterns and 3D motifs into their face design.
The Ultimum is available in CarbonCore Aluminium and Aluminium Clad Timber profile systems, both of which deliver thermal performance at the highest level. The CarbonCore Aluminium construction provides an exceptionally rigid, thermally broken frame system, while the Aluminium Clad Timber option introduces the warmth and natural beauty of timber on the interior face — an important consideration for homeowners who want the architectural quality of the Ultimum range inside as well as out.

To specify an Ultimum entrance door is to make a definitive statement about the quality of the home it serves. These doors attract genuine admiration — not through ostentation, but through the kind of quiet precision and considered design that reveals itself progressively, rewarding every closer look.
The German Design Award recognition is not incidental: it reflects a product that has been judged by an international design community to represent genuine advancement in the field.
Ultimum doors are specified by architects and their clients on projects where the entrance sequence is understood as a critical element of the architectural experience — where the front door is the first and most memorable detail a visitor encounters, and where that detail must perform flawlessly for decades. All Ultimum doors are installed by Zakuna’s trained installation teams, with precision-fit frames and a full suite of high-security hardware options.
