The timeless modern town villa is situated on a plot with a south-western orientation in the sought-after Krefeld Stadtwald residential area. Due to building regulations, the building was constructed to the rear of the plot, with the garden and access at the front. Picture credit: Photographer / architect Georg von Houwald
Architect Georg von Houwald has skilfully integrated the contrast between lightness and weight in his design. At the front, the upper floor appears to hover above the ground floor. The set back upper part of the building creates space for a circumferential, secluded rooftop patio. Picture credit: PCI Augsburg GmbH
The Krefeld tiling professionals not only laid the 50 x 80 cm quartzite natural stone tiles throughout the ground floor, they also tiled the adjoining patio behind the floor-to-ceiling windows with tiles of the same size. The generous, continuous tiling concept supports the spacious, bright impression of the rooms, in particular in the living area. Picture credit: PCI Augsburg GmbH
The dynamic interconnection of interior and exterior is one of the architectural principles of the modern residential building. The effect: a lot of natural light and an open view of the outdoor area. Picture credit: PCI Augsburg GmbH
At the heart of the basement is the luxurious spa area with the 350 x 350 cm large jacuzzi, sauna and fitness room. Transparency and natural light also define the architectural concept here. Discreet lighting supports the high-quality ambience. Picture credit: PCI Augsburg GmbH

Step by step, the patio takes shape. In order to ensure optimum adhesion, the tilers apply Carraflott NT to the back of the natural stone with 6 mm toothed trowel. The slab is then turned over and tapped into place in the fresh Pavifix DM mono grain screed. Picture credit: PCI Augsburg GmbH
The Pavifix DM is mixed with water in a free-fall mixer before being applied to the single grain mortar membrane in a 5 cm thick layer. Picture credit: PCI Augsburg GmbH
Accuracy comes first: once a 5 cm thick layer of PCI Pavifix DM has been applied, Benjamin Wyß checks the evenness of the surface. Picture credit: PCI Augsburg GmbH

In the spacious living area on the ground floor of a town villa in Krefeld, large, floor-length windows allow in plenty of natural light. The high-quality natural stone flooring gives the impression of spaciousness and airiness, linking the interior to the outside. A total of 400 m2 of calibrated blocks of quartzite natural stone were laid: 200 m2 in the living area and 200 m2 on the patio. The continuous 50 x 80 cm format is 2 cm thick inside, and the regulatory 3 cm thick outside. The contractor Benjamin Wyß and two of his appointed sub-contractors first tiled the bathrooms. The screed was then primed with PCI Gisogrund to seal it and prevent it from being affected by moisture. The professionals laid the 1 cm thick porcelain stoneware tiles (60 x 120 cm) on the wall and floor of the bathroom on the first floor with PCI FT Flex. The bathroom and the guest toilet on the ground floor were tiled with a natural stone covering in keeping with the general tiling concept on that floor using PCI Carraflott NT. PCI Carrafug was then used to grout the joints.
The staircase between ground floor and the cellar is tiled with 60 x 120 cm porcelain stoneware cut exactly to the dimensions of the steps. The rooms in the cellar and the bathroom in the guest apartment integrated in the cellar were tiled with 60 x 60 cm and 60 x 90 cm porcelain stoneware. At its heart lies the elaborate spa area which includes a 350 x 350 cm large jacuzzi and a round shower. Wyß first primed the screed with PCI Gisogrund Rapid. PCI Rapidlight was then used to apply an adhesive layer for the PCI Pecilastic U waterproofing and isolating membrane. The joins between the membranes were covered with PCI Pecitape 120 and PCI Seccoral 2K Rapid, as were the base areas and connections such as to the pool. The tiling professionals used PCI Lastogum on the primed wall substrate. The two seals were joined along the base area with sealing strips. The expansion joints and the connections between the wall and floor were sealed with PCI Silcoferm S and then grouted with the versatile PCI Nanofug grout.
The rear wall of a niche in the entrance area reveals a mosaic in black-and-gold natural stone with a tile dimension of approx. 1 x 1 cm. On the ground, the quartzite natural stone surface runs from the living room out to the patio. The border between inside and out almost disappears when the floor-to-ceiling windows are opened to the roughly 200 m2 large patio in the summer. Whilst tiling, the installers sealed the sloping concrete slab and the steps with PCI Seccoral 2K Rapid and system sealing strips. This was followed with a single grain mortar membrane, then a 5 cm thick layer of PCI Pavifix DM mono grain mortar. A 6 mm right-angled tooth trowel was used to apply PCI Carraflott NT to the back of the natural stone slabs that were then tapped into place in the fresh single grain mortar. Wyß and his team then grouted the whole area with the PCI Pavifix 1 K Extra special joint grout. Installed in this way, the patio is impervious to all climatic and mechanical stresses.
