This was only possible with optimum use of available floor space, affordable yet useful and meaningful interiors, improved space saving designs and customer oriented approach.
This sounds like a PR person describing how a builder/interior designer had produced a house or flat that was a masterpiece of planning - in their opinion.
To normal people, it means something like:
This was made possible by making sure that every square inch of the extremely limited floor-space was used as efficiently as possible (i.e., to hide the fact that it was too small for anybody more than one metre tall); and that the best possible use was made of: fixtures and fittings that were supposedly practical and pretentiously stylish, but didn't cost more than twice what you would expect, and which were too small to be of any use. All this was done so that we could charge the highest price and manage to fool you into thinking that we had your needs in mind.
