  • For Peter Berg and his team, 2024 has been a very pleasing year so far. With innovative slope design and sustainable natural stone plant combinations, our team not only secured first place in the ‘TOP 100 Planners’ ranking, but also received an award in the ‘Gardens of the Year’ Award 2024 from Callwey Verlag.

    This means that we have won the four most important horticultural awards in the German-speaking world in just nine years. These include the Elca Green Award, the Gardens of the Year Award, the Oase Award and the Taspo Award, all of which recognise the outstanding work of garden designer Peter Berg.

    A striking example of the philosophy is the project for an urban garden in Bonn, which won the ‘Gardens of the Year’ award in 2024. This project illustrates how sustainable garden design and the preservation of old trees and shrubs can enhance urban spaces.

    Peter Berg’s natural and aesthetic garden design has established itself as a trademark – the ‘BergStyle’ – through the innovative use of natural stone. This style is characterised by the transformation of difficult slopes into impressive garden landscapes and unique plant-natural stone combinations.

    We are delighted to have received these important awards. It shows us that our philosophy and passion for sustainability, natural stone and the fusion of nature and design is being recognised.

    Modern companies now offer their employees a lot. From ergonomic seats to openspace offices with meeting lounges, a relaxation corner, a café bar, freely available drinks and fruit to a fitness studio – a good company boss cares about the well-being of his team. For some time now, however, the importance of “green” has been recognised here as well. Not the colour on the wall, but outside, around the building or in inner courtyards, in the form of a garden. Why is the topic of “company gardens” increasingly becoming the focus of companies? The renowned garden designer Peter Berg from Sinzig has himself recognised a few years ago that there is an enormous potential for companies in this area. In the following he names 10 good reasons for a company garden:

    1. the appreciation of the employees

    The creation of a green outdoor area shows the employee that the management really cares about what is good for the employees. Of course it’s an extra investment for the company, but it’s an absolutely worthwhile investment in employee well-being. This kind of appreciation is gratefully accepted.

    2. employee generation

    A company stands and falls with good employees. When selecting an employer, however, a potential employee also pays attention to various criteria. The work-life balance plays a central role today. A company garden, which allows the connection to nature and also reflects the appreciation of the employee, is a big plus. Perhaps a playground would still be an idea for the company’s own nursery, which is often the case with larger companies.

    3. employee satisfaction

    The possibility of spending time in the countryside during working hours has a relaxing effect and is an ideal balance to office space or work hall. Employee satisfaction increases, which in turn has a very positive effect on the general working atmosphere.

    4. increase in creativity

    Fresh air and the feeling of being in nature have been proven to stimulate creativity and performance. Pausing and conferencing in a well-designed outdoor area promotes the flow of ideas and interactions between employees. There are various possibilities for them to communicate together or to seek peace and quiet.

    5. productivity increase

    A relaxing and creativity-enhancing environment naturally also leads to an increase in productivity. A rather stressed employee, who is often under stress, can hardly work productively. Natural plants, daylight and oxygen have a calming and stimulating effect at the same time.

    6. reduction of sick days

    Many workers suffer from psychosocial stress at work, which often leads to illness and absenteeism. This is an unsatisfactory situation for employers and employees alike. Through the many positive effects of a company garden, this stress is reduced, the general well-being is increased and thus the number of sick days is significantly reduced.

    7. improvement of the microclimate

    Environmental pollution or heat often affect the climate in and around the company building. The professional use of plants, natural stone and/or possibly water is an ideal way to improve the microclimate. Plants absorb CO2 and filter fine dust. At the same time, they release oxygen, keep moisture in the soil and provide shade. Natural stone absorbs the heat of the day and stores it. If it is watered, the moisture evaporates and also contributes to the improvement of the microclimate.

    8. environmental awareness

    Sustainability and environmental awareness are topics that have been in the spotlight for some time now. The design of a garden impressively documents that a company takes up these issues and is aware of its responsibility in this respect. Apart from ist own surroundings, this measure also contributes to the greening of cities and makes them more liveable.

    9. green business card/image improvement

    The corporate philosophy plays a major role in its image cultivation. The external design of a company is now perceived just as much as the website or business equipment. An ecological imprint and sustainable action is credibly proven by a company garden. The first impression counts – with the customer, like with the potential coworker, and that is to represent the quality of the company and the products.

    10. increase of the real estate value

    Last but not least – a factor not to be underestimated is the influence of a professionally and aesthetically designed outdoor facility on the value of the property as a whole. Here, too, it makes a difference, of course, whether a picture is monotonous to the observer from the outside.


    These are certainly sufficient good reasons to think about this topic. In the meantime, there are outstanding examples worldwide of how garden designers have realized the importance of green for companies. Be it as an outdoor facility, patio, i.e. courtyard or roof garden, adapted to the architecture and philosophy of the company, the design is more formal or more natural. Even a large complex can be beautifully integrated into the surrounding landscape.

    A company garden is a wonderful opportunity to bring nature to the company and to use its powers.

    Originally, the garden planned and planted by Peter Berg and his team at the Arp Museum was a temporary project. At the end of 2019 the magnificent combination of natural stones, perennials and trees was to be dismantled to make room for something new. All the more reason for us to be pleased that it has been decided that this beautiful work will remain in existence for another year.

    A few current impressions can be found here.

    The front garden must not do any work
    It must be easy to care for and therefore make as little work as possible, until no work at all. Today this is more and more the maxim. Especially in modern new buildings one sees increasingly a stone desert of coarse gravel instead of a front garden designed with plants. This is not good for the eye, the insects or the climate. Garden designer Peter Berg therefore pleads for more naturalness in front of our front doors. Above all, we should use more woody plants that bind the fine dust, produce oxygen and lower the temperature.

    Easy-care aesthetic front garden design convinces
    As an experienced garden designer, Peter Berg knows that a natural front garden created with planning requires little maintenance, but offers many advantages. A well thought-out combination of structure-giving natural stone with selected, long-lived plants considerably reduces the maintenance effort. At the same time however thereby an ecologically valuable range is created, from which humans, as well as nature profit. Also the optics is substantially more convincing and raises at the same time the value of the entire real estate.

    Foils and gravel are no problem solvers
    If you want to have an ecological and natural garden, an understanding of nature is indispensable. Unfortunately, this is becoming increasingly rare today. Especially in the front garden area the large area use of gravel is preferred. This testifies to an unnatural relationship to “cleanliness” and the belief that one would never have work like this again. However, this is a deceptive conclusion. “Nature always seeks its way,” says Peter Berg. Even supposedly dense foils and heavy rocks do not help. An entry of weeds from the environment cannot be avoided, and when trying to remove them, one inevitably gets stuck in the foils.

    Trees improve the climate
    Especially in our ever warmer climate and summer temperatures approaching 40 degrees, large deciduous trees are particularly important. They provide protection for humans and animals from increasingly intense solar radiation. At the same time, they are real climate-improvers. With their foliage they create a light shade and contribute to cooling the environment. The evaporation of water has an extremely positive influence on the environment, which also benefits other plants. In addition, woody plants absorb CO2 from the air and give us oxygen. Even fine dust, which now pollutes not only large cities, is absorbed by them.

    In Berg’s front garden alone, you can already see five different types of trees and shrubs that adorn it with their lush greenery. Attractive grasses and shrubs are planted underneath. “In nature, every piece of soil is covered with plants,” explains the expert. “There is undesirable vegetation only if it is not planted closed or the plants do not fit together.

    Woods, shrubs and grasses offer birds and insects an ideal habitat, improve our climate and create a piece of nature in our private sphere – and this also includes the front garden.



    Yesterday a delegation from the company Arteza Landscape Design from Moscow visited the garden designer Peter Berg. Together with some colleagues and the director of Arteza, Dimitriy Onishchenko, as well as Mrs. Knack from the Lappen tree nursery (who were also the tree sponsor for the Arp Museum), Peter Berg’s private garden was first paid a visit before we proceeded to the Arp Museum. The subject of gardens is generally very topical in Russia, and in Moscow in particular. Investments are not only being made in private gardens but also in urban greenery, and Arteza is leading in this sector in Moscow. Peter Berg reported that they were able to use the time for a very refreshing and interesting exchange.

    The gardener and philosopher Karl Foerster described them as “grasses are the hair of Mother Earth” and they are gaining increasing levels of influence in the design of new gardens. Not only is their innate lightness impressive, but in addition, their many possible uses are an absolute enrichment for every plantation. “They bring a fourth dimension to gardens. In even the lightest wind they clearly show movement,” explains garden designer Peter Berg. They create the connection of the garden with the landscape.

    Cutting at the right time
    Both the selection of grasses – some spread wildly or sprout underground – and the right cutting time are essential. According to Peter Berg, pruning should take place “preferably in springtime shortly before the budding, a hand’s width above the ground”. Soon fresh green sprouts out, growing into filigree stalks in spring. In summer, inconspicuous grass might well reward with a flowering splendour. And even in autumn and winter these plants have their very own charm; adorned with frost or snow or delicately illuminated by the rays of the winter sun.

    The right combination makes the difference!
    The selection of grass varieties should absolutely depend on the conditions of the garden. Is the location dry, humid, sunny or half in shadow? How much space does the grass need, does it grow upright or does it arch to the side? The surrounding planting is also of importance. The combination of spring onions and grasses is particularly recommended, as they already provide an attractive garden bed in spring. “Small, simple wild forms should be given preference over large-flowered tulips and daffodils,” says Peter Berg.

    Early weeding
    Unwanted plant species have plenty of space to spread on uncovered soil. Some are carried in by the wind, others already slumber in the ground. Peter Berg therefore advises early weeding, especially when planting new plants, in order to prevent strong seed production and thus wild growth from the outset. Because once the weeds have blossomed, they quickly seed themselves in the bed and begin to dominate.
