20 years of creating extraordinary architecture and design

I believe that architecture has a direct influence on the quality of our lives, and it is my passion to design and create spaces that are uplifting and inspiring to use.


As an architect I am excited to make a difference, to solve problems, to put a smile on someone’s face, to never stop learning and to design outstanding buildings that enhance our daily lives and respect the natural world.”

From our studio in Palma de Mallorca we work on projects in the Mediterranean and worldwide.


The common goal in all projects is to maximise the potential of each site and to develop a design response that relates to the unique features, opportunities and challenges of that site.

Together with the clients brief this drives our design approach, resulting in a great variety of forms and expressions in our architecture.



From greenluxury® villas to innovative high-rises, we create sustainable, high-end architecture and interiors.


To this end, we focus on excellent design, management and communication with our international clients.

Through in-depth site analysis and the use of advanced 3D models we develop architectural solutions that are special to each site and enhance the design, cost and time certainty of the projects.


Bringing together our background from Mallorca, London and Hamburg, we combine sophisticated detailing and technology with natural materials and vegetation: “Precision meets Nature”.



Mathias Koester has 20 years of experience as project leader, architect and associate for the renowned architecture offices of Foster+Partners,  Rogers Stirk Harbour+Partners and Massimiliano Fuksas as well as for project developer Arquiproject Mediterraneo.


In this time he held key roles in the design and building process of several ground-breaking buildings,

many of which have become award winning icons in their location.

In parallel Mathias Koester Architects was founded in 2007, focussing on the design and construction of innovative and sustainable family homes and holiday houses, and since recently larger commercial projects and hotels.
