Sometimes I think Cleveland's lack of rowhouses has been a real impediment to redevelopment in the city. The wood-frame housing stock in some city neighborhoods isn't much different than what you'll find in the suburbs -- just older and more decrepit. Granted, city houses tend to be more densely grouped, yet sometimes I think they don't offer a living experience different enough from that of the suburbs to attract a critical mass of newcomers. For many Greater Clevelanders, I think it boils down to: Why live in a shabby woodframe house in a crime-ridden, downtrodden neighborhood with few amenities when I can live in a new one in the green suburbs? (An exception to this way of thinking would be in a neighborhood like Ohio City, which offers cute Victorians and apartment buildings.) In cities with rowhouses, meanwhile, the houses themselves offer something novel and charming in their urban-ness.
Still, I believe there's hope. All of Cleveland's neighborhoods have dense commercial corridors (e.g. Detroit, Lorain, Euclid, W 25th), something the suburbs can't offer. Perhaps revitalizing these will be the key to luring people back to the central city. Also, Cleveland has more apartment buildings than Columbus or Cincinnati (particularly in Edgewater), as well as old warehouses that could be (and are being) converted to live-work lofts (Midtown).
As for the new townhouses, I like some of them, but most I find completely ugly. The biggest problem with many is that the architecture is simply tasteless. Montana Townhomes are an example; so are those pastel, vinyl-sided monstrosities in Detroit Shoreway that they built 5-7 years ago. I can't get into Beacon Place; it seems like a misguided attempt to create a suburban subdivision in one of the city's most urban locations. Why the set-back???
On the other hand, the pics above from Ohio City look very nice, and the Franklin Townhomes in Detroit-Shoreway (http://progressiveurban.com/franklin_th/fthIndex.html) could also be cool, though it's hard to tell from the rendering.
Finally, while we're on the topic of Cleveland rowhouses, don't forget the legendary Hessler Street! Not traditional Eastern rowhouses by any means, but connected -- and very funky in a good way.
