Daniel Peabody, the developer, created six apartments in the space, which is one of a handful of smaller rental projects in the downtown area either completed or now under consideration in the latest wave of apartment development. Most of the projects are large scale, the biggest being the conversion of the former bank office tower at 777 Main St. into 286 units. Peabody's project and another similar-size one two blocks away, at 36 Lewis St., aren't as high profile but are taking their place in this spate of redevelopment, putting formerly blighted buildings to a new use.
