Where there had been only seven houses in the Heights in 1807, by 1860 there were over six hundred of them, and by 1890 the area was almost completely developed. The buildings were designed in a wide variety of styles; development started in the northern part, and moved southward, so the architecture general changes in that direction as the preferred style of the time changed over the decades. Throughout the 19th century, Brooklyn Heights remained an elegant neighborhood, and became Brooklyn's cultural and financial center. Its development gave rise to offshoots such as Cobble Hill and, later, Carroll Gardens.
