This section outlines the uses and appropriateness of architectural designs and features that give commercial districts and outdoor spaces their personality.

Orientation of New Buildings
The BBB Main Street Design Committee encourages and recommends the following.

  • New buildings should face a street or other public space. Buildings should not front directly onto parking lots.
  • New buildings situated on street corners should have two facades. Both walls do not need to provide their own entrance, but the façade without a door should not be a blank canvas. Rather, it should be an extension of the façade with the entrance—its design should be integrated with the “main” wall of the building.
  • Off street parking areas should be sensitively located to the side or rear of the building. This layout will reduce the visual impact to and disruption of the streetscape’s continuity.

Scale and Mass of Additions
The BBB Main Street Design Committee encourages and recommends the following.

  • The overall scale, massing and proportions of new additions should relate to and be compatible with those of adjacent and surrounding buildings. Changes in scale and mass, such as offsetting a wall(s), or deviating from the existing roof line should be made in graduated increments.
  • Buildings should not have long, uninterrupted flat walls.
  • Designing wall offsets, adding changes in floor levels, including windows and ornamentation to exterior walls should be used to add interest and variety.
  • Roof line offsets, gables and dormers should be utilized to vary the massing of the roofs of buildings.
  • Visibly exposed sides of new additions should be defined with a base and cap or cornice.

Materials and Details of Additions
The BBB Main Street Design Committee encourages and recommends the following.

  • All materials, details and colors used with new additions should be compatible with the overall design of the original building, as well as with surrounding buildings.
  • New additions should be well integrated with existing structures.
  • Architectural features and motifs of the original building should be retained and repeated in the design of new additions whenever possible.
  • When designing additions, the patterns, colors, details and prominence of materials used in adjacent buildings should be taken into account.
  • Aluminum and vinyl siding and trim materials are not recommended.

Roofs and Walls of Additions
The BBB Main Street Design Committee encourages and recommends the following.

  • The new roof form (its shape) should be appropriate to imitate the existing building’s roof.
  • In new additions, the use of gables, dormers, masonry chimneys, cupolas and similar elements is encouraged where appropriate to the design of the existing building.
  • Flat roofs should be avoided on one and two story buildings.
  • The façade of a building should be emphasized through window patterns and proportions and the enhanced treatment of entrances through details, materials and architectural motifs.
  • The design of visible side and rear walls should be compatible with the façade. The use of blank, windowless walls is discouraged. However, if they are absolutely necessary, they should utilize surface articulation and architectural elements found in other wall facings.

Service Areas and Mechanical Equipment
The BBB Main Street Design Committee encourages and recommends the following.

  • Loading areas, waste facilities, air conditioning units, exhaust and vent stacks, elevator penthouses and antennae should be located to the rear of buildings or screened from view.\
  • The use of interior refuse rooms in lieu of outdoor dumpsters or other methods of waste removal is encouraged. Exterior refuse containers and dumpsters should be screened from view.
  • Fire escapes should not be visible when viewing the façade.
