Sort the portfolio by the reader's house, not by your best work
Homeowners are matching against their own room, and a gallery organized by style makes that impossible.
The visitor has a galley kitchen, or a bathroom with no window, or a house from a particular era with the constraints that come with it. They are looking for evidence you have worked on something like it.
Most portfolios are organized by nothing, or by style categories that mean something internally. Neither helps somebody find their own situation.
Grouping by room type, layout and era works far better. Small kitchens, galley layouts, primary bath reconfigurations, houses of a particular vintage.
Captions should name the constraint. Saying that a wall could not move, or that the plumbing stack fixed the layout, turns a photograph into evidence rather than decoration.
Before images are essential here and frequently missing. The transformation is the argument, and a nice finished kitchen without its starting point could have been anybody's.
