I'm in another Plazacorp building. We were able to purchase upgrades directly from the supplier. So, we did our colour choices with Plazacorp (and there was a wide range of options), but if we wanted a different configuration in the kitchen cupboards, for example, we worked directly with Paris Kitchens. If there are things you want to change (one area where there wasn't much choice was kitchen backsplash), find out who the supplier is and contact them.
