The artists of De Stijl strove for more and better cooperation between the arts without each art form losing its independence. The reason for this was what they saw as the architect's role being too great. The greatest results were expected from the collaboration between the architect and the painter. It was then the painter's task to 'recapture' the flat surface of architecture. Van Doesburg wrote about this:
{{blockquote|Architecture provides constructive, therefore closed, plastic. In this she is neutral towards painting, which provides open plasticity through flat colour representation. In this respect, painting is neutral towards architecture. Architecture joins together, binds together. Painting loosens, dissolves. Because they essentially have to perform a different function, a harmonious connection is possible.{{sfnp|van Doesburg|1918a|p=11}} }}

In 1923, following the De Stijl architectural exhibition in Paris, Van Doesburg also involved the 'unenclosed (= open) space relationship' of furniture art on architecture. He subsequently regarded architecture as a 'synthesis of new visual expression'. 'In the new architecture, architecture is understood as a part, the summary of all the arts, in its most elementary appearance, as its essence', according to Van Doesburg.{{sfnp|Engel|2009|p= 43}}
