This is a group of speculative offices built between 1987 and 1988 in two phases, designed by Campbell Zogolovitch Wilkinson and Gough (CZWG) as part of the Aztec West business park. The buildings are constructed with a light steel framework, faced with red and buff bricks and pre-cast concrete elements.

The design consists of two square blocks with central inner courtyards, joined by a circular entrance court. Two further semi-circular entrance courts are positioned at the diagonal corners.

The two-storey buildings feature banded cladding of red and buff brick with pre-cast concrete dressings. Full-height vertical window strips create the impression of columns, complemented by engaged 'capitals' referencing a continuous concrete architrave, a similar treatment applied to projecting sills. These details draw inspiration from Ricardo Bofill’s Les Espaces d'Abraxas in France. The cornice is accentuated by projecting concrete edgings alternating with brick courses, terminating in projecting points at the ends of the semi-circular entrance courts. Each entrance court has a vertical break in the facade containing an entrance gate with curved metalwork and a metal balcony above. Rendered semi-circular arches mark flanking entrances to the office units, with later replacement canopies. Louvred doors, mirroring the office entrances, are located at the diagonal corners and provide access to service areas. The inner courtyards are paved with concrete in a herringbone pattern, surrounding a circular gravelled area bisected by a path with seating. A first-floor covered balcony runs around the edge of each courtyard, featuring semi-circular patterned metalwork to the balustrade, a wooden handrail and brick-clad walkways of a herringbone pattern. A split staircase fire escape is located at one corner, providing access to the balcony, which also has pairs of drainage chains connecting to the courtyard floor.

Inside, each two-storey courtyard block is subdivided into two L-plan office units with courtyard access. Staircases and restrooms are within the office entrances. The staircases include tubular handrails and a section of open-tread metal stairs to the first flight. The open-plan office spaces have been refurbished.

The entrance courts feature concrete herringbone-patterned paving, including a circular 'turning circle'.
