Chicago in 1857. Blocks of 80, 40, and 10 acres establish a street grid at the outskirts which continues into the more finely divided downtown area. A city block, residential block, urban block, or simply block is a central element of urban planning and urban design.
One acre equals 1 ⁄ 640 (0.0015625) square mile, 4,840 square yards, 43,560 square feet, [2] or about 4,047 square metres (0.4047 hectares) (see below).While all modern variants of the acre contain 4,840 square yards, there are alternative definitions of a yard, so the exact size of an acre depends upon the particular yard on which it is based.
There is a train station and a few office and apartment buildings in Broadacre City, but the apartment dwellers are expected to be a small minority. All important transport is done by automobile, and the pedestrian can exist safely only [citation needed] within the confines of the one-acre (0.40-hectare) plots where most of the population dwells.
For example, if a lot must adhere to a 0.1 FAR, then the total area of all floors in all buildings on the lot must be no more than one-tenth the area of the parcel itself. In other words, if the lot was 10,000 sq. ft, then the total floor area of all floors in all buildings must not exceed 1,000 sq. ft.
A characteristic of the size of a lot is its area. The area is typically determined as if the land is flat and level, although the terrain of the lot may not be flat, i. e, the lot may be hilly. The contour surface area of the land is changeable and may be too complicated for determining a lot's area. Lots can come in various sizes and shapes.
From a distance, massing, more than any architectural detail, is what creates the most impact on the eye. [6] Architectural details or ornaments may serve to reinforce or minimize massing. [7] Because it has a direct relation to the visual impact a building makes, massing is one of the most important architectural design considerations. [1]
There are various distinct design features in cluster development notably: the consideration of natural features/topography, smaller lot size, the use of cul-de-sacs, and the use of certain waste/storm water management techniques. Along with site design, waste/storm water management design features are a principle aspect of cluster development.
In the tectonics as envisioned by Bötticher, the function (defined as requirements for internal space) had driven the design: the size determined the roof technology to be used, the latter in turn mandated the support requirements, creating a structural outline of the building, architecture was an art of resolution of the conflicts between the ...
