But be aware the Detolf cannot fit modulars like Town hall or Fire Brigade because the the spacing between shelves cannot be adjusted. Even the Grand Emporium won't fit into Detolf unless you remove the roof bill board sign.
Billy bookcase shelf is will not fit any modulars also as the baseplate depth required is more then 20cm.  I use Besta for its 40cm depth so it can even fit a large grey base plate.

Glass doors and lighting is available but optional.
