In a world where trends are changing faster than ever before, the question arises: How do we design spaces that last? Justin Howlett, an interior designer from Munich, relies on a combination of timeless elegance, high-quality materials and sustainable design. In our interview, he shares his inspirations, challenges and his vision for a more sustainable future in the interior sector.
Inspiration from the past for the future
Justin Howlett describes his style as the result of a development process that has taken years. He studies design history intensively and draws inspiration from old architecture and interior books, renowned design magazines and modern digital platforms such as social media: "I always find it fascinating how many modern solutions existed already decades ago and how innovative previous generations were in interior design."
He is particularly interested in the mid-century era, which is characterized by clear lines, well-thought-out material combinations and functional aesthetics. Many of these designs have lost none of their modernity to this day and show that good design is timeless. That is why he deliberately integrates vintage furniture into his projects. These not only have a high level of craftsmanship, but also carry a history that gives rooms depth and character.

Sustainability as a fundamental principle
For Justin Howlett, sustainability in interior design is much more than a question of materials - it's about designing rooms so that they last for many years. A room shouldn't have to be completely redesigned after a short period of time, but should be able to grow with the residents. That's why he makes sure to use materials that are durable due to their quality and workmanship. Wood, natural stone and high-quality fabrics are at the heart of his design, as they are not only aesthetically pleasing, but also develop a beautiful patina over time and thus gain character.
In addition to the choice of materials, the origin of the products also plays a major role. Short transport routes and sustainable production are just as important to him as resource-saving manufacturing. Instead of buying new furniture, he often opts for well-preserved vintage pieces, which are more sustainable than many modern mass products due to their longevity. Especially in times when goods are readily available and interior trends are becoming more fast-moving, he sees it as his job to sensitize his customers to conscious and sustainable furnishings.

The Challenge of Transparency
A key problem in sustainable design is the lack of transparency: "Important information about materials and manufacturing processes is often missing. It takes a lot of research to find out which products are really sustainable." Here, he sees it as his responsibility to raise awareness among his customers and actively suggest sustainable alternatives. This research can be time-consuming, but for him it is essential for making informed decisions.
He also talks about the difficulties in obtaining reliable information: "Sometimes sustainability is used as a marketing tool, but when you take a closer look, it turns out that the product is not as sustainable as it is advertised." For him, the most important thing is to enter into dialogue with manufacturers and follow up.

Timeless designs instead of short-lived trends
Justin sees the fast pace of the interior design world as a challenge, but also as an opportunity: "I try not to be guided by every new trend, but to create a basis that lasts." A well-thought-out basic structure and flexible design elements offer the opportunity to introduce personal changes without having to redesign the entire room concept. Materials in particular play an important role here: natural fabrics, hand-crafted furniture and long-lasting colors ensure that a room can develop over the years without losing its relevance.
For him, this also means not blindly following trends, but observing them first. "Just because something is new doesn't mean it's good or will last long. I let trends sink in first and then decide whether they actually make sense." This principle prevents customers from being dissatisfied with their interior after just a few years and having to make major changes again.

Interior Design and Health
For him, sustainability also goes hand in hand with a healthy living environment: "Natural materials not only contribute to aesthetics, but also influence our well-being. A good indoor climate, pleasant feel and the right choice of material play a decisive role." He sees a strong connection between design, sustainability and health, especially in the area of interior textiles such as bed linen and carpets.
He emphasizes that a sustainable space should not only be environmentally friendly, but also people-friendly. Materials should be free of harmful substances and create a pleasant atmosphere. "Especially when we talk about carpets or bed linen, it is important that they are not only visually appealing, but also feel good and contribute to the indoor air quality.

Sustainable design selection as the key to quality
Justin Howlett appreciates it when design is chosen consciously and carefully. He is particularly impressed when companies and designers do not just make decisions based on visual aspects, but also pursue a sustainable strategy. He sees sustainable design as an investment in the future - not only for the environment, but also for the people who live in these spaces. For him, quality comes before quantity: those who consciously choose long-lasting, high-quality handcrafted products create an environment that is not only sustainable, but also aesthetically convincing.

Conclusion: Design consciously and grow over time
Justin Howlett reminds us that good design takes time and should grow carefully. Sustainability is not a short-lived trend, but a necessary step towards conscious living. His approach shows that those who design with quality, origin and longevity in mind not only create beautiful rooms, but also a sustainable home.
Finally, he gives a practical tip for anyone who wants to furnish their home sustainably: "Good design doesn't have to be expensive. If you take your time, look for second-hand treasures and focus on durable materials, you can create beautiful rooms with simple means."
