Floor plans are commonly used drawings and we hear a lot about them. Interior elevations aren't too far behind- but a floor finish plan?? Raise your hand if you know what this one is for!
Honestly, I just enjoyed imagining people reading my blog and raising their hand all Horshack style (and if you don't know who Horshack is, you have some TV to watch...)
When complicated (several transitions/patterns) floor finishes are used, designers use floor finish plans to indicate any detail locations for transitions (how does the wood floor connect to the tile floor- a wood floo moulding? A Schluter metal strip? A simple grout line?), the direction the flooring runs, and what type of flooring is being used.
This drawing will note whether the finish runs up to built-in items, or does it run under them?
While this is a fairly simple drawing, it is incredibly helpful for the contractor and allows the designer to define these transitions without causing the regular floor plans to be too busy. Not all projects will have a floor finish plan. It ultimately comes down to the complexity of the finishes, and drawing needs.
