Clay brick in three places

Like a custom-tailored suit: This residence in Hasbergen was tailored to the needs of its residents both inside and out. For the façade, walls, and entryway, the Engelshove architecture and engineering office relied on a natural product – bricks.

This house in Hasbergen, near the German city of Osnabrück, draws attention to itself by using bricks in three places – in the façade, walls, and paving. When during the planning process did it become clear that bricks would be the right material here?

Anja Engelshove: The front of the house faces the street on the south and is the representative side from which you enter the building. Behind the house, there is a patch of forest with some old trees. Therefore, the idea was for the façade to make a strong visual impression and for the building materials to provide long service life and low maintenance despite the proximity to the forest and humidity. From the very start, these aspects dictated that we would use bricks for all three purposes. 

„In our planning, we often rely on clay bricks as building material. Bricks are a sustainable natural product which remains beautiful for a long time. They do not change shape or colour, they are UV-resistant, and they are stable and extremely durable.” - Anja Engelshove,  Engelshove Ingenieurbüro

What were the arguments for using clay bricks for these three different purposes?

Anja Engelshove: We are very fond of façade bricks, and in our planning, we often rely on clay bricks as building material, for façades as well as on the roof and for garden paths and paving. Bricks are a sustainable natural product which remains beautiful for a long time. They do not change shape or colour. They are UV-resistant, and they are stable and extremely durable. When building walls, they offer heat insulation and ensure a good interior climate; on the façade and for paving, they provide aesthetic advantages since they can be used to create a uniform image. We designed the entryway in dark clay, which is reflected in the façade, but at the same time, the façade also distinguishes itself through contrast. Laying the bricks in different ways offers another opportunity to play with different looks.

Did the principals have any special requests for this project?

Anja Engelshove: The family wanted to build a barrier-free house for the next stage of their lives, one which can later be used as a residence for older people and provide space for children and guests. The upper stories can be converted into a separate residential unit later on, for example. The customer also had very clear ideas with regard to the selection of the material and the colour concept. The request was for a very classic, calm façade which incorporated colour play and thus was also interesting. That's why we selected bricks as the material for the façade.

Why did you select Terca Eco-brick® for the façade?

Jochen Engelshove: Shortly before we started planning, we were at the construction trade show Batibouw in Brussels, where the new Terca Eco-brick® was presented. We liked the product very well even at the trade show: On the one hand, these bricks are sustainable due to their low mass, for a narrower brick means less energy during firing, less clay, and lower resource costs. On the other hand, we also gained space thanks to the narrower size. We were convinced of the advantages and wanted to try out the Terca Eco-brick® right away. In the meantime, we've been using this sustainable product in many projects.
 
Anja Engelshove: The emphasis on the size was not as important for the project in Hasbergen since the construction site allowed a flexible building size. Of course, it was still an advantage in the planning and resulted in a few square meters of additional living space. The decisive aspects for selection of the façade brick were the look and the variety of colours available in this product line. The mixture of brown, natural-coloured, and somewhat earthy tones, as well as the classic red appealed to us a great deal.

How were you able to persuade the customer of the virtues of a façade brick which was not yet widely used in the construction industry?

Jochen Engelshove: At the latest during the second conversation, we take specific visualizations of concepts to our customers. We always use Wienerberger's textures for this, so that it's easy to see the surfaces and effect of the façade in the visualization. Furthermore, we work with samples, which show the interplay of bricks and mortar close-up.
 
Anja Engelshove: We selected a mixture of colours and prepared sample surfaces. The colour mixture was then finalised directly on the sample surface: The principal wanted to have a little more red in the mixture, for example, which resulted in this unique composition.

You work primarily in private residential construction. Are customers asking for anything different with regard to sustainability?

Jochen Engelshove: Yes, absolutely. Everyone is talking about the topic of sustainability in construction, and customers explicitly ask about this. When it comes to funding, the framework conditions have changed: Applicants can only obtain loans on favourable terms or qualify for particular subsidies if certain sustainability aspects are taken into account. Therefore, there is a real focus on this topic.

What, in your opinion, makes a beautiful façade?

Anja Engelshove: We always like it if all the bricks produce a uniform surface and harmonise with the paver bricks in the garden – or, as things are here: with the paver bricks in the entryway. Bricks retain their look over the years because they are UV-resistant and they can be cleaned again and again. In particular for this project, which is right next to the forest, the benefits of a brick façade are clear: A plaster façade would have required renovation after just a few years; the brick, by contrast, will retain its look for the long term. That's certainly a requirement for our architecture: We want to build timeless projects. A façade is a decision which will last for years and decades. Therefore, timelessness plays a key role in both the look and construction.

Which aspects of the house in Hasbergen do you especially like to remember?

Anja Engelshove: We built a beautiful building, one in which the large expanses of glass and the bricks go together perfectly. The flowing façade surrounds the generous openings in the building and forms a visual frame of brick. The solid brick façade and playful bricks – that’s what we find the most inspiring.
