Coblonal Interior Design Studio

Who we are and what we do

COBLONAL INTERIOR DESIGN is a study of architecture and interior design led by Joan Llongueras and Jordi Mercè that has participated in more than 400 projects throughout its 20 years of activity.

We design, develop and produce all kinds of projects for housings, offices and commercial premises everywhere.

We deal with the whole process. We act as architects, interior designers and decorators to define and develop the project. Then we take charge of its management and production as a construction company. From the initial concept to the smallest detail, offering keys in hand.

How we work

In Coblonal Interior Design we always start from a deep understanding of the needs and preferences of ours clients and the proximity with them, to look for the balance between the beauty and the maximum functionality.

We put our creativity to the service of the client, adjusting our own style to the characteristics of each case. Whether it is space, we develop solutions specially designed to make life easier for our clients.

Thanks to our experience both in the design of the interior architecture and in the subsequent construction and production of our projects, we have acquired a global vision of the process that allows us to ensure the formal and economic success of any project during all its phases until the last detail.



We will visit you in your home or business to know the space and your needs. In that same visit we will draw up the general ideas and scope of the interior design project, to then make an approximate calculation of the fees and guide you in the costs of production and execution.


Coblonal Interior Design will show you different proposals of distribution and finishes. We will decide jointly the most suitable proposal to cover your needs. We will develop the executive project for the realization of the work and define the style line, putting in parallel the process of administrative licences.


With the executive project we will value the production in a detailed budget and we will realize an optimum planning of the production. We will coordinate the action of the different professionals in the construction management, with an exhaustive follow-up of the finishes to guarantee your final satisfaction.
