Newer condos & townhomes in the Danbury area go in all shapes, sizes and layouts. The advantage of this is that you can find a community that you feel the most comfortable in, location, amenties as well as having the space set up in a way that best suites your lifestyle.  The most common layout set up is a tri level. The advantage of having three different levels of space (living area level, bedroom level, and basement) is that you can divide the space and minimize noise from public areas to sleeping areas.  Three level townhomes are available at Woodland Hills, Sterling Woods, Kensington Woods, Stetson Place, Arlington Woods, Lake Place and others

The second most popular set up for townhomes in the Danbury area having 4 levels of space. The extra level is created by either having a loft space in (as is the case for some of the floor plans in Woodland Hills) or creating a level along the slope from the garage (kind of a sub basement) which was done at some of the units over in the Westville Commons. You do get a some additional living space, but it might be difficult to do things like calling people to something & also could be difficult to climb the stairs if you get ill or incapacitated.

There are surprising very few two level units. Some communities that offer two level units (main level, and either an upper level or basement) include of the set ups in the Poet's Landing community and Summit View (Old Brookfield Road). Some two level units are in older (20 years or so) such as Park Ridge, Lakewood, Arrowood and Barclay Commons. 

There is a very small supply of newer ranch style units. They are desireable because they are typically easier to clean and maintain. They are also good if you become in a position where climbing stairs can be difficult.  There are ranch units models in Poet's landing & Crystal Bay (both with direct access to Candlewood Lake) Lake Place, Westwood Village, Barclay Commons, Shepherd Hill as well some units in the original section of Sterling Woods.
