A snout house is a house with a visually dominant garage. The following is language I'm proposing in the rewrite of my town's zoning code. The first paragraph is based on language in the Aurora, Colorado Zoning Code. (The adopted code will use both English and metric measurements.)
202.15.01 Avoiding garagescapes. New housing development should avoid front elevations that result in a streetscape consisting mainly of rows of garage doors ("snout houses,” tail pipe architecture," “garagescape”). A front-loading garage may occupy up to 50% of the house linear frontage. For each run of four or more houses (lots in a row along one side of a street between two streets), up to 25% of all lots may contain houses with street facing garage doors that project 8’ or more from the front of the dominant building line. Remaining lots must have alternately-loaded garages, such as recessed garage doors, side load garages, rear entry garages, recessed detached garages, and/or similar types of garage orientation where the garage doors are located less than 4’ in front of the building line.
202.15.02 Three car garages. Garages that are designed to serve more than two cars must be designed so garage bays beyond the first two are recessed by 4’ or more from the main garage frontage.
