A relatively modest percentage, up to 12% of all new units, may be designed as two-family dwellings and a further 8% may be designed as three- or four-family dwellings. If an applicant elects to pursue the option for two-family and/or multifamily dwellings, which require a conditional use permit, such dwellings shall be designed either to reflect the Township's historic building tradition or shall be designed to resemble large single-family residences, with particular care taken in the arrangement of front doors, driveways and parking areas. When different housing types are proposed, the applicant shall be strongly encouraged to integrate them architecturally and in scale so that they can be mixed within the same streetscape and not isolated from each other in separate areas.
