Villa W
Frankfurt am Main
(Under Construction)

This white monolithic house delineates a striking demarcation between the public and private realms. From the street, its north facing facade looks and feels impenetrable: the entranceway is recessed; the first floor, windowless; and its top floor fenestration, well set back. By contrast, the south elevation is completely glazed.

Surrounding properties are a mixture of two and three storey pitch roof housing. All have been carefully referenced in determining the project’s massing. And, as a way of a vertical counterpoint to the villa’s robust horizontality, the traditional chimney is elegantly defined as a slender block-like form.

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. Externally, the house is finished in a mineral based render, which preserves the breathability of the walls. Furthermore, as there is no 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, measuring 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 substantial structural framework allows for the insertion of a dramatic double height space (6m x 6m x 3.4m), so enabling these interiors to function as one large, interconnected two-tier cuboid.

The glazing to the south elevation comprises a series of triple pane units: three for both the ground floor and first floor (3.5m x 2.8m, 3m x 2.8m and 3.5m x 2.8m), and two for the top level (3.5m x 2.4m and 3.8m x 2.4m). In addition, a substantial glazed section (6m x 2.8m) within the west elevation enhances the quality of light to the kitchen and dining area, as well as playing an integral part, along with the south façade, in bringing the outdoors in and vice versa. A continuous flooring surface, comprising coquina stone slabs, running throughout the living room and the adjoining L-shaped terrace, provides the other major component in delivering this inside-outside connection.

Building on this dynamic, the villa's top floor, pavilion-like configuration enables the house 'to step outside' its immediate suburban neighbourhood. Full height glazing on three sides offers scenic views of the surrounding countryside, the Taunus mountain range being visible to the north. Diffused light from a skylight, situated above the stairwell, creates a sense of expectation as one ascends. On fine days the ambience is heighted by diagonal rays of light via the south-west glazing.

This delicate use of light is equally on show at the front of the house. Here, a rectangular slot is detailed in the overhang above the recessed entranceway, and a full-height sandblasted glass panel integrated within the entrance design. Together, these gently illuminate the hallway, the light becoming brighter as one moves through the building and into the project's tour de force: its two-tier, open-plan living space - a composition that both celebrates and disseminates the villa’s spatial tectonic narrative.

Villa S

Villa S is a cast in-situ concrete house, dramatically sited on a hillside above Schriesheim, in Baden-Württemberg, in southwest Germany. From its elevated position, the building offers panoramic views of the surrounding countryside: to the south, the Black Forest; to the west, the Palatinate and the Rhine Valley; to the east, the Odenwald mountain range; and in the foreground, on a neighbouring hillside, the ruins of Strahlenburg Castle, originally built in 1295. Within this setting, the project presents itself as an elemental two-tier structure.

The white concrete has been well honed, the culmination of years of perfecting its use, perfecting the right mix, the quality of shuttering and the waxes applied, to ensure a smooth matt finish. Here it is used within a massing composition that generates a strong sense of place, rooting the villa in its culture and topography.

The lower level is articulated as a heavy concrete cuboid, embedded in the landscape. The walls are Romanesque in stature, which is the result of the double concrete wall system, the solidity and density of which is strikingly disseminated at the front of the house, courtesy of the deeply set glazing. Structurally, the internal wall is loadbearing, allowing the outer wall to function as formidable facing. With this block, bedrooms and bathrooms are safely cocooned. Above, the pavilion like configuration engages with the landscape and the elements.

The ground floor plan comprises three interconnected but well-defined zones. The first of these is the garage and the entranceway, the latter including an external staircase to the lower ground level and garden. The central zone houses the living area and kitchen, and the building’s stairwell, its upper landing providing access to both the garage and a toilet and washroom facility. And situated on the south facing side is the large terrace, accessed via three elegant sliding glass panels. Brazilian slate tiling runs continuously throughout the interior and exterior creating a stunning inside-outside space, measuring 135sqm.

The downstairs layout is larger, measuring 175sqm. This comprises the two south-facing bedrooms, with floor to ceiling glazing, both having en-suites bathrooms; a central area, which is capable of accommodating two additional well-sized rooms; and towards the rear, a utility and washroom, a general storage space, and a dedicated room for the building’s electrics and heating system.

From a volumetric standpoint, the rooms on both levels are generous and well-proportioned, with the ceiling heights measuring 2.6m for the lower level and 2.8m for the ground floor. The main living space is the building's prime asset, suffused as it is with natural daylight and commanding as it does spectacular views. In keeping with this grandeur, and to harmonise the upper volume as whole with the lower block, the roof is articulated as a bold horizontal plane. This cantilevers 2.6m beyond the living area on the south side; and on the north side manifests itself in part as a seemingly gravity canopy which emphatically defines the entranceway. This is in fact a rigorous piece of structural engineering, which comfortably dissipates the weight of the suspended concrete frame through the building's upper massing. The large rectangular slot (5m x 4m x 0.6m) delivers a dramatic interplay of light and shadow, while ensuring that a dedicated covered pathway runs through to the front door.

Throughout the scheme, the Meranti doors and window frames provide a strong aesthetic counterpoint to the white concrete while elegantly complementing the slate flooring, and the opaque matt glass panels that form part of the fenestration.

This holistic approach to detailing is also evident in the building's bespoke light fitting which delivers both internal and external coverage; works within the structural parameters of the concrete ceilings; and complements the architecture's exacting, pared-back aesthetic. Existing fittings were unable to meet these requirements, hence the development of the villa’s very own luminaire.

The outer casing, which measures 12cm x 12cm x 8cm, is milled from a solid block of aluminium. Internally, the fitting comprises 49 1W LEDs mounted on a platina plate, combined with a highly polished stainless steel reflector and a specially satinized plexi-glass cover. The finished product is a low energy, high performance lamp that delivers an even spread of emitted light. Furthermore, it sits perfectly flush to the ceiling, so respecting the ascetic clarity of the cast in-situ concrete.

The villa's asymmetric plan orchestrates the lighting layout, hence the spacing of the three lamps along the south-facing cantilever, the one offset from the middle aligning with the building’s long axis. Save for this subtle lighting detail, the south façade's symmetry robustly counterbalances the asymmetrical arrangement that organises the north elevation.

This dialogue between the north and south facades is in itself counterbalanced by the dynamic between the heavy mass of the lower level and the lighter structure above - the former generating a connection with the earth, the latter a connection with the sky. These axial relationships animate the building, enriching its narrative. In short, this is architecture exploring the poetic and communicative potential of tectonic construction. The result is a dwelling that looks and feels timeless, completely at home in its surroundings.
