Dear reader, Having recently joined Wienerberger as their Sales Director responsible for the Koramic Clay Roof Tile product range, it comes as no surprise to me that we have a great wealth of products and solutions to offer architects. When people ask me what’s so special about Koramic roof tiles, the answer is always “Our range of clay roof tiles is not only innovative, but it’s extremely successful globally”. That’s a fantastic thing to be able to say and it gives me tremendous pride and pleasure every time I do – which, if I’m honest, is quite often. How many times have you looked up at a buildings roof and noticed a new detail in the design and wondered how the architect came to choose the solution you see before you? In this issue of Architectum, you will see new and varied applications and read how Koramic have enabled design solutions to be implemented across Europe, from Denmark to Cyprus. With an eye for detail you will see such varied examples as pantiles on a Finnish parish to blended tile solutions in a Dutch village. Nearer to home is an example of traditional clay pantiles on a Grade 1 listed manor house conversion. Waveney House is now open for business after a three year renovation programme that has seen the 500 year old manor house transformed into the sympathetic and stylish Waveney House Hotel. Under Koramic’s guidance, clay plain tiles and profile tiles have expanded into a very real alternative to concrete for value for money and aesthetic appeal. And while I’ve got my “sales head” on, I’d like to mention our new roof tile showroom in Manchester. Many architects are finding it easier than ever before to specify and detail our range of tiles with the confidence that they have specified a clay tile with the backing of one of Europe’s largest construction material companies. Alternatively why not visit our informative web site on www.wienerberger.co.uk I hope that you enjoy the new magazine format, and look forward to hear from you soon.

Steep roofs on scattered buildings make modern village [The Netherlands]

> A modern village has come into being in Vleuterweide, not as the result of ribbon development or houses clustered around a church, but through a diversity of volumes, many roofs and scattered parcelling. The 73 houses in a subsector of the Utrecht Leidsche Rijn Development Plan that were designed by the architect’s firm Feekes & Colijn all originate from a two-storey basic model under a steep pitched roof. This roof shape, covered with clay roof tiles, comes back in the various extensions, the basic model can be adapted to suit larger house types as well. Visitors and residents alike call the Boomgaarden in Vleuterweide a smurf district with little gnome houses. But for project architect Anke Colijn this is by no means a disparaging comment. On the contrary, she takes it as a compliment that shows that her idea of creating a small neighbourhood with a rural atmosphere with very bold houses has turned out to be a success. And this village character rapidly generates a social fabric that enhances the quality of life and imbues a sense of security.
Identification Anke Colijn: “Identification is key word for all our projects. If the residents can identify with where they live, this contributes to their well-being. This not only encourages deep involvement and subsequently a durable environment, but also has an economic impact because people feel better and do not fall ill so easily for example.” Colijn stresses out that identification

Bricks and roof tiles give massive block’s scale, dimension and contrast Rudy Uytenhaak puts a finishing touch to Amsterdam stadium neighbourhood [The Netherlands]
> >
> Next to the beautifully restored Olympic Stadium in Amsterdam, the architect’s firm Rudy Uytenhaak designed a massive housing project. Always ready to experiment with materials, they created closed yet open façades with flat roof tiles and ridged bricks. The detailed features of the cladding materials give the massive blocks scale, dimension and contrast. And all in complete harmony with the stadium neighbourhood. In the luxury residential project on the Laan van Hesperiden in Amsterdam-Zuid, project architect Marco Romano from the firm Rudy Uytenhaak adopted the design elements of the adjoining Berlage urban development plan. In addition to the closed and plastic character of the large areas of masonry, the façades comprise tiles, slate or zinc plates, and interspersed sandstone features. Romano saw the opportunity of meeting the client’s wishes by means of an innovative use of brick. The urban development plan called for a design with massive blocks whereas the client BPF Bouwinvest wanted façades with many windows. Romano hung brick strips on the façade. These strips dominate one’s impression of the façade when approaching from the side (“on the run”), giving the building a maximum brick look. The more the façade is approached from the front, the more it seems as if the strips make up only a fraction of the façade, making possible a wide view from the large windows.
Self-expressive tile surfaces Analogous to the architecture of the existing development, Romano opted for tiles as the cladding material for the closed façade sections and the top storeys. The Migeon Actua flat tile has the same reddish-brown colour as the brick but differs in structure and reflection. Whereas the brick has a rough profile, the tile is flat. Because the same material was chosen – graded by clay colour – the project does not break up but remains a distinct coherent entity. On the top

the brick is somewhat less overpowering. This effect is also enhanced by the façade sections in the plinth of the building, which are made of concrete blocks.
Craftsmanship This residential project represents the latest final piece in a respectable district. For years, the edge of the Berlage urban development plan had a typical frayed edge here. The high architectural values in this Amsterdam Stadium neighbourhood still continue to command respect. This is also shown by the way in which architect, contractor and producers worked together in this recently completed project. Their expertise and professional dedication resulted among other things in a choice of materials and detailed finishing of equally high merit, which combine to give the project scale, dimension and contrast. Moreover, this was not a case of indiscriminate imitation but the judicious deployment of modern and innovative resources and techniques. Incidentally, the total project comprises more blocks than those designed by Rudy Uytenhaak. The other blocks were designed by the architect’s firms of L. Lafour and R. Wijk (who supplied the urban development plan together with Hans Ebberink) and Mulleners & Mulleners, all from Amsterdam.

church and the oldest building in the Helsinki area. The church’s oldest parts date back to the 1480s. Sustainable building was therefore also a requirement for the new parish office.
Innovative architecture The project was designed by architects Lahdelma & Mahlamäki. The complex of two massive linked buildings with double pitched roofs (50°) is located near the old church and next to buildings from the last decades, many of which have red brick façades. The two separate buildings lie diagonally to each other and are joined together by a large entrance, which opens on the river, the rocky forest and the old church.
Actua roof tile set the tone The main materials of the complex are red facing bricks and clay roof tiles from Wienerberger. The project manager at Lahdelma & Mahlamäki, Mr. Marko Santala, explained that the roof tile, Koramic Migeon Actua, was selected first and all the other materials (bricks, plaster, aluminium framework and glass) were then chosen to match the colour of the clay roof tiles.

Natural surroundings The French government looks after its coastline. Consequently, the number of locations for holiday accommodation is limited. In 1995, the Vanhaerents Group did not hesitate for a moment when they had the opportunity of buying a plot of almost 8 hectares bordered by the sea, a golf course and a nature reserve. The project was carefully prepared in cooperation with two architects: Els Vanhaerents and Bernard Laffaille. Their design comprised of 8 village buildings with 160 apartments that overlook the sea or the golf course, and 100 houses that

> Research Park Waterfront is emerging cautiously in the former clay pits of the Kapittel brickworks in Niel. In the master plan, the architects exploited the existing differences in level and also specified the use of natural building materials. They thus laid the development-planning basis for a project that fully respects the site and its past. In previous decades, the clay pits in the Rupel region near Antwerp created a great deal of fuss. With the gradual disappearance of the brick industry, a number of pits were used as rubbish tips. This practice was ended by many years’ protest and growing environmental awareness. In recent years, a great deal of thought has gone into their much-needed conversion.
Choice location The area concerned comprises of 32 hectares and is criss-crossed by four pits. The varying water level and local conditions have produced a unique flora. This choice location for a science park that is connected with the University of Antwerp found a number of private and public partners. For the urbandevelopment master plan, they called on AWG Architects and the architect’s office Ferre Verbaenen. The latter also designed the first and currently only building.
Urban-development footprint Bob Van Reeth (AWG Architects): “As our office always does, we started from the spirit of the location for the master plan. In this case, I knew the site through and through because I grew up in the neighbourhood. We put a straight road in the irregular landscape and used the differences in level to obtain volumes with different storeys. From the road, they all have the same cornice height. In order

Once upon a time …
Modern residential district with traditionally built houses
In Poznan, western Poland, there is a residential district whose borders are shaped by dwarfs, fairy tales, Brzechwa and Tuwim. The latter two are the names of well-known Polish writers of children’s fairy tales. The district is called ‘Osiedle Bajkowe’, which is Polish for fairy-tale district. Bajkowe is situated in a green part of the city in Grunwald near Marcelinski Forest. Fifty-two detached houses were built using traditional technology. Every one of them has brick walls, roofs covered with Koramic clay roof tiles and attractive back gardens, as well.
