In planning terms, neighbourhood character is shaped by design elements that unify the look and feel of an area. These elements can be referred to in community-based planning policies or local policies. Patterns of streetscape are established through repeated setbacks, the placement of garages and landscaping, for example. Building forms can have similar heights and massing (lot coverage), roof pitch, dormers, window placement, and porches. The choice of materials can also be a unifying element. By creating an area plan that guides future development, community-specific policies can help ensure that new development is sympathetically integrated with existing buildings.
