Frankfurt am Main

These monolithic structures, which are constructed out of prefabricated concrete columns and platforms, deliver a dramatic and substantial balcony solution to this late nineteenth century apartment block, perfectly complementing the building's scale and massing. Both towers are freestanding as an historic preservation order protects the property's external fabric.

The concrete’s etched finish - the result of extensive testing with several 1:1 samples, incorporating various aggregates and pigments - references the use of red sandstone in the door and window trims. The objective here was not to copy the painted treatment of the material, but rather to articulate its core qualities - its colour, composition and texture - within a concrete template. And as a way of a counterpoint to the scheme’s solidity, self-supporting stainless steel railings elegantly enclose each floor plate.

The spindles in each railing section are set into 50mm deep countersunk stainless steel bushings. These cylindrical holes are precisely aligned, the result of being configured as a single unit within the pre-cast concrete mould, welded together with steel rods to eliminate any potential movement. In addition, during the casting process each bushing was fitted with a plastic insert to ensure its volumetric integrity. A circular steel plate surround completes the detail; these encase the spindles, slotting into the bushings and sitting flush with the floor.

Internally, the platforms are detailed with a 2% fall to allow for drainage. 3cm thick sandstone slabs, positioned on footings, provide a safe and durable walking surface, in keeping with both the concrete and building’s use of sandstone. Throughout the scheme, the modular nature of the architecture is subtly disseminated by a 10mm shadow gap detail.

In essence, the project’s materiality, tectonics and geometry represent a seamless integration of making and thought, culminating in two contextually measured structures that are well-honed, well-grounded and well-proportioned.

Villa W
Frankfurt am Main
(Under Construction)

Villa W resides in a suburb of Frankfurt. From the street its white monolithic form seems impenetrable, its windowless façade and recessed entranceway delineating a clear demarcation between the public and private realms. Surrounding properties are a mixture of two and three storey pitch roof housing. All have been carefully referenced in determining the project’s scale, mass and proportions. A series of setbacks on floors one and two allude to the timeless ziggurat form. And as a way of a vertical counterpoint to the building’s robust horizontality, the traditional chimney is articulated as an elegant rectilinear column.

The villa’s physical presence is palpable. The monochromatic walls are Romanesque in stature, which gives the building its immense sense of permanence. This is architecture communicating through its structural ontology the importance of place and dwelling.

The scheme utilises a restrained palette of materials: for the externals walls, one course of high insulation clay blocks; for the internal configuration, cast in-situ concrete. The house is finished in a mineral based render, so preserving the breathability of the walls. As there is no specific insulation layer used in the build, the clay blocks are specified at 450mm thick in order to achieve the desired U-values.

Villa W provides 640 sq metres of living space over four levels. The floor-to-ceiling heights are generous: 2.4m, 2.8m, 2.6m and 2.4m, from the lower ground level to the second floor, respectively. The main social spaces, a living and dining area on the ground floor and a gallery/study on the first floor, are located to the rear, orientated towards the garden via the fully glazed south facing elevation. Here the building’s structural credentials, courtesy of a large inverted concrete U-frame, allow for the insertion of a dramatic double height space (6m x 6m x 3.4m), which articulates these interiors as one large interconnected two-tier cuboid.

The glazing to the south elevation comprises a series of bespoke triple pane units: three for the ground floor (3.5m x 2.8m, 3m x 2.8m and 3.5m x 2.8m); three for first floor (3.5m x 2.6m, 3m x 2.6m and 3.5m x 2.6m); and two for second floor (3.5m x 2.4m and 3.8m x 2.4m). The scheme’s tectonic rigour is further disseminated through the inclusion of a substantial glass unit (6.0m x 2.8m) to the ground floor west elevation.

The second floor L shaped composition has full height glazing on three sides, which provides scenic views of the Tanus mountain range. A skylight situated above the stairwell delivers diffused north light. This soft, even illumination creates a sense of expectation as one ascends, which on fine days is heightened by diagonal rays of sunlight via the pavilion’s south west glazing. By contrast the north facing façade is solid, save for a translucent glazed unit as part of the front door design. The entranceway is recessed, allowing for a large rectangular slot to be detailed above. The resultant light gently illuminates the hallway, enabling the dwelling’s south elevation to draw one through and into the villa's main living area, a volumetric composition that disseminates the building's spatial tectonic stature.
