- Quality street environments are established where each home positively addresses the street
- Convenient and safe routes between the parking space and the house are provided
- Car and cycle parking is safe and secure
- An efficient use of the land is achieved
Grouped parking located in basement, podium and undercroft structures are integrated into the overall design of the terraced housing scheme.
When parking is in structured situations the design should also address:
- Optimal use of any slope to accommodate structured parking in an efficient and low impact manner.
- Quality shared and private open spaces are created on top of structured parking.
- Blank edges to structured parking are avoided / shielded or contained behind single-aspect ground level habitable spaces.
This section discusses the positive and negative attributes of basement, podium and undercroft parking, and offers better design practice and rules of thumb for achieving quality outcomes.
Advantages of grouped (basement, podium and undercroft) parking
- Land is efficiently used particularly on sloping sites.
- Access to the dwelling is provided.
- There is an opportunity to secure and monitor the parking area.
- Cars are hidden from the public realm, with opportunity for high quality amenity space above.
- Basement parking under terraced housing can maximise engagement between the ground level of the house and the street.
Disadvantages of grouped (basement, podium and undercroft) parking
- This type of parking is more expensive than surface parking.
- It provides little or no access to natural ground or soil depth, to provide for mature tree planting and landscape amenity.
- Fee-simple titling cannot be used, although unit-titling with rights to a parking space can.
- Exposed edges of parking structures can be unattractive.
- Front doors located off the podium level or in the basement can be difficult for visitors to find, and less welcoming than front doors accessed from the street or from an at-grade accessway.
- The design is complicated and will require specialist experience due to the greater complexities involved in providing high amenity open spaces and good quality journeys to the front door.
- Undercroft and structured parking can create unsafe areas due to limited natural surveillence.
