This design was unique in providing the most storage options in an easy to construct manner. However, the focus on storage especially the full-height shelving on either side of the kitchen might make the small space feel more constricting than it already is. Perhaps going with floating shelves throughout or open back shelves by the door to the front room would have opened up the space more while still providing the unifying element the design aims for. Also, while the uniformity of all the open shelves is aesthetically appealing, it may not provide the diversity of storage options (particularly closed storage or closet space) that a renter in this small unit might desire.
I very much appreciated the sourcing of elements and appliances and found the sliding door in the bathroom a great way to save space without compromising function.
