Jaspar Jansen and Jeroen Dellensen

The recognized creators of “The Room of the Roof” of the Bijenkorf Tower, the German Jaspar Jansen and Jeroen Dellensen, founders of the studio i29 Interior Architects, are for Colección Interiorismo the perfect combination between interior and exterior architecture for any space, that is to say, the conception of harmony in architecture.

Architecture in Harmony


The profound admiration that Colección Interiorismo feels for Jaspar Jansen and Jeroen Dellensen was born by carefully observing their work; it immediately transmits to us simplicity and equilibrium, and as they said, a touch of contradiction in its elements, denoting their attention to the object and providing themselves with energy and choosings, which at last result into pure and charismatic spaces with a purpose and an environment.


The work with Jaspar Jansen and Jeroen Dellensen  is clearly guided towards design solutions, without depending too much in the materials or the technique, and being its principal engine the resolution of problems and questions of those who inhabit it, having spaces that respond to the necessities of its inhabitants in an architectural detailed model, based in the conceptual outline of their clients and their needs; everything without depending in a unique conception of its creators, the result: minimalist and custom spaces.

On the other side, another essential point of admiration for Jaspar Jansen y Jeroen Dellensen, arises through structural designs and architectural pieces that compose unique spaces, which together with the selection of functional furniture and visual impact elements, develop into suppliers of a great part of the solutions that can be offered to any person.


The innovation lies in personalization, in the specific paths chosen and which guide us to great goals, materialized in a lot of awards as the Rotterdam Design Award, the Dutch Design Prize for best design, and The Great Indoors Award for best office, samples of their talent and continuous reinvention of spaces; so from this, we will show you some of their best achievements in interiorism:

Jaspar Jansen and Jeroen Dellensen – House 7


The unique object of elegance through simplicity and functionality which isn’t in fight with beauty through wood and white walls, a combination that seems to be made in heaven; light entering from all parts, and that inclusively, strains through the walls; wholes that not only encourage that sensation of transparency and translucency, but that also have a useful purpose by creating a versatile functionality of storage and decoration; definitely cleanness and brightness that, in contrast, talk about the family who inhabits it and their simple but complete life.

The necessity to exclaim for tranquility and comfort through the usage of whites and greys that together bring us a work space that, at the same time, talks us about compromise and productivity, achieved through active tables without apparent separations, walls that serve as canvas for ideas and reunions, and ludic and reading spaces which invite a work area to become a true life environment, transporting us at the same time, to the client’s necessity of transmitting care and concern for the persons who work in it.

Jaspar Jansen and Jeroen Dellensen – School 01


The objective: a vibrant environment, perfect for a place designed for a young dynamic population always in continuous movement, and that same colors, conforming blocks, stairs, tables, and benches which have an individual spirit. All the previous, without forgetting the evident reinforcement, and at the same time, the sensation of diversity and multiculturalism that any modern and educative space has to have.

The goal of having a space that speaks for itself of style, achieving that through modules which talk about trends and fashion that seem to trespass art; each space is a world, and everything contrasting in white and black frames, perfect photos for trends and desire pieces that everyone want to touch and buy. Is it a gallery or a cloth store? A doubt that instead of questioning, accentuates.

as any other conversation that you may have,

because when you talk about building a house,

you talk about dreams.
