HDPF is led by two Partners – Nikolaus Hamburger and Francisco Ferrandiz.

The professional spectrum of HDPF extends from consulting and planning to realisation and construction management. The practice covers a wide range of architectural projects, including multi- and single-family houses, conversions, renovations of listed buildings, office buildings, commercial facilities and urban development tasks.

HDPF is member of the SIA Swiss Society of Engineers and Architects and the FSAI Swiss Federation of Independent Architects.

Mission statement

Thoughts and conversations

The following text is an account of a series of thoughts arising in conversations led by Nils Havelka and held at the office of HDPF in the winter of 2016.

When the HDPF partners talk about architecture, they talk about doing. Their way of thinking accords with their equally stoic and considerate actions. It seems to me that in their world-view, architecture is an immense field of diverse tasks and the sub-tasks they entail, which they must address with openness, curiosity and above all with respect, since they all contribute to the quality of the product. Instead of being an unfamiliar intellectual framework, this represents an infrastructure (Heidegger would have spoken of "Gestell" or "frame") that allows the architects to supervise the creative process in every way, in each of its constituent aspects and with complete focus. Their approach makes no distinction between the process and the product; the perfectly tidy model construction room, the excellent coffee, the well-rested designing architect, the select wooden-shell chairs, the beautiful handwriting, the well organised budget sheet - they all contribute their consciously created qualities to the process and ultimately to the building. Such organisation is designed and maintained in the same way as architecture itself. It blurs the distinction between the process and the product, thereby allowing the protagonists to discover new potential, sharpen ideas and also consciously use them in the future - sometimes in a way that can overcome the separation of professional occupations that has established itself since Modernism. In the case of the construction of the Meister house, the architects spent nights at the building site to learn the effect of treating the concrete's surface at first hand;

to create its haptic and visual qualities through hammering, grinding and sand-blasting, and then communicate that to the building manager, thereby achieving the project's incomparable spatial experience today. These holisitc methods reflect a far-reaching willingness to think and work one's way into new fields and achieve their synthesis; they are also particularly valuable at a time sustainability and urban sprawl, can only be spatially grasped in a fragmentary way since they are the result of a countless sum of autonomous actions and themes that affect the political and constructed landscape of Switzerland. Today, architects are assigned building tasks that are recruited from this complex carpet of the constructed environment. Whether large or small, urban or rural, monofunctional or complex: each task can create qualities specifically at its location and be applied to that location. A well-used property with a high level of design and building quality contributes to sustainability on account of its long life-cycle and density. Its careful expression creates identity and acceptance for dense development. Its placement is able to give the location a new spatial reference and spatial qualities. The high architectural aspirations are implemented not only with respect to the location, but also in connection with its qualities as a result of a continous synthesis of the complexities of contemporary building. The synthetic underlying approach of the office thereby guides the countless sub-processes through the economy of means to their ultimate formulation as constructed reality.
