I know what you mean. There is a slight flaw in this set, if you have a big preference on style, as some of the furniture is very reminiscent of house plan technical drawing clip-art found on Apple Macs in the 80s - some of the seats are just too perfect geometrically.
0one Games have adopted an interesting niche, they sell plans which print in blue ink - which was the adopted colour of the inside cover maps in the TSR modules 70s-80s. Nostalgia is powerful thing.
It's a nice set though, good value. Putting together only part of the floor plan is very satisfying.
