It's definitely a step up from the rest of the South Barrington neighbourhood.
The exposed columns columns could turn out ugly but there are cases of them working well. The main thing I would change is the colour of the top "container". I think it blends in too well with the bottom one and a sharper contrast would be more interesting visually (think light brown). Also the two strips that run through the middle section of the building should stand out (a nice dark colour like navy blue). This would completely change the structural requirements of the buildings but actual repainted shipping containers would be AWESOME!
