A while ago I got a couple of copies the DOTS Jewellery Stand set 41905 which were going cheap. This gave me four of the distinctive 9×9 white heart-shaped plates (part 65486) which I decided to use as the floor plan of a new office block for Micropolis.
I also had lots of transpareent 1×1 light blue bricks, so these were the immediate window choice. I then found some bright light yellow bricks to complement the windows and used a staggered pattern across each floor to build up the height.
It is called Hartshaped House and is the Headquarters for a clothing company, Hartshaped Fashion.
