A townhouse is generally considered be a detached or a semi-detached type of housing unit that is found in urban environments within major cities. A prime example of such structures can be seen in the famous brownstone townhouses located throughout Brooklyn, New York. Some designs will include a terrace as an additional feature, but this is not a necessity. These properties are known to be found in rather upscale areas of a city although a considerable amount of work has been done to restore those that are located in run-down locations.
In modern sense, townhouses will normally contain two or more floors; many offering a third with additional attic space that may be converted into a loft. Most townhouses are considerably old; some dating back centuries. As such, the most exclusive have been modified to offer all of the modern conveniences of 21st century living.
Spacious townhouses are of a particular interest, for they are excellent for larger families or for a couple that is expecting a child. As these are the exception as opposed to the rule, real estate prices for such structures will tend to be quite high although the recent economic crisis has served to moderate these figures somewhat.
Townhouses with more internal area will make the best use of the existing environment; often times demolishing walls that do not bear a significant structural load and installing wide windows and skylights that will contribute to an open-air atmosphere. These are some of the main factors that allow spacious townhouses to be an exceedingly attractive real estate option.
