Primitive as primary geometric figures. Primitive as computer language called the simplest solid objects. Primitive as, in English, are defined original, coarse and wild objects. Primitive aims to fragment and destruct. To reduce aggregated forms to elementary geometry. Nothing more and nothing less than volume, crucial and bearing structure, strength and vital consistency of materials. Nucleo makes unrepeatable and one-off objects: divans, armchairs, tables, lamps, and bookcases are made entirely by hand without the use of mould and are finished with non-toxic resins that reveal all marks and imperfections.
