is a studio for interior design, construction and art.
based in berlin, germany

 We design and build custom furniture, unique room concepts and art installations.


We are Anna Wolff and Jan Tiemann. 

Jan is a trained carpenter and interior & furniture designer, while Anna studied fine arts. 

Jan has an immense love and passion for wood. His vast knowledge of the material and his wide experience working with it shapes his designs and his way of constructing and building.

Anna’s intuitive sense for shapes and colors combined with extreme patience and attention to detail finds expression in her often colorful and meticulous work.

We’ve known each other since teenagehood and been going on life’s adventures together ever since.
We’ve been discussing and supporting each other‘s projects for years. In 2018 we started fusing our skills in joint interior design projects.

For our common mission as a creative duo we founded in the middle of something. 


We live and work in Berlin, Germany.

Our workshop is located at Fahrbereitschaft in Lichtenberg.

We also like to travel : )
If you live anywhere else – don’t worry! Please contact us to see if a collaboration can be arranged.


We are two friendly individuals who work together in a close collaboration. As a duo we provide you with the full service of designing and also constructing your project.

We come to your house, we drink coffee with you, we play with your kids or pets - we get to know you and you get to know us, so our project can develop on a fundament of common trust.
We want to really understand your ideas, wishes, needs and dreams. We bring all of our imagination, creativity, passion, knowledge and experience to the table and do everything to make them come true.


Our furniture is built by hand – with precision, passion, patience, love and appreciation of the material.

We like to work with wood, but often use materials that are non-conventional in furniture production.

We love to combine the wood with colour and other materials, like for example natural stone, terrazzo, concrete, brass, copper, artisan tiles.

how to work with us

1) contact us

Write us an email and let us know a little bit about your project! If you have any question – ask away!

You can write us in English or in German.

We will call you to have a first conversation about your project and the way we work and we can schedule a first appointment.

2) receive an offer

After our first conversation we will write an offer for the design phase of your project.

One of the first questions is often about the price, and this one is usually not easy to answer in the very beginning, as we usually don’t know much about what you need from us yet.
In order to estimate a realistic price we need to know exactly what we will be creating {e.g. size, complexity, materials, time frame etc.}

That is why we always split the project in two phases and write two seperate offers - one for the design phase and one for the construction/ realisation of the project.

If you have a specific budget in mind, that you don’t want to surpass, you can let us know and we will estimate whether it is realistic or not and possibly plan the project within the possibilities of the budget.

3) design phase

The offer for the design phase contains:

1) First meeting - getting to know each other, getting to know your project, seeing the space, taking measures.

2) We sketch up our ideas and prepare a few variants.
Second meeting - we present and discuss and decide about the designs and talk about materials and details to add.

3) Detailed design of chosen variant. Here we plan every detail of the project. In the end of this phase you receive a detailed drawing and an offer for the construction phase.

The offer includes a term that gives you the option to stop the collaboration after each of the three phases mentioned above, and you only pay for the completed phases.

4) construction phase

The offer for the construction phase contains:

1) Execution planning and pre-construction/ building

2) Delivery & installation on site. Depending on the size and complexity of the project it can take a few days to install it. We will coordinate the dates with you in advance.
With your permission we will take some pictures after completing it.

Both offers are all-inclusive. That means the price is binding and will not be surpassed.
