Boundaries and Edges
Well-designed places clearly define the boundaries for private, shared and public spaces, making it more likely that occupants will use, value and take ownership of them.
The impact of a site’s boundaries on the immediate surroundings and the way in which the building(s) interact with the edges and ground around the site should be considered at the outset as an integral part of the design. Boundary treatments should be integral to the design of the building and landscape.
Practical aspects of the site layout should not be overlooked. Strategies for fire and emergency access, cleaning, repairs, waste collection, and rooftop plant and equipment should be considered when planning the site. The design impact of these aspects should be fully considered and sensitively incorporated into the building design.
Features of tall building boundaries and edges
- Well-articulated, active ground floors
- Well landscaped sites with appropriate spacing between buildings
- Contextually appropriate boundary treatments
- Active boundaries
- Hidden servicing and plant
Ground floor articulation
The ground floors of tall buildings must be well-designed and articulated to create a human scale and add interest at street level.
Principles of activating ground floor
Building is set back with an outdoor area for ground floor cafe
Building is set back at first floor to allow small terrace area for users above
Active ground floor uses
Tall buildings must incorporate active frontages at ground floor level.
Examples of using active different land uses on ground floor
A variety of land uses can be used to activate ground floor and they should be mixed to ensure people activity throughout the day.
Offices and retail leisure units on bottom three floors. The first floor can overhang to create a covered collonade for certain uses.
Retail, cafes, restaurants or other leisure uses on bottom two floors of building with parking podium to rear
Offices on two ground floor levels with basement parking to allow access to rear communal area
Residential uses are possible on ground floor but should be set back to allow for private space between public boundary
Landscape coding requirements
The applicant must demonstrate that the proposed layout has been informed by a site wide landscape strategy, that includes landscaping proposals, SuDS are a natural approach to managing drainage in and around properties and other developments. Sustainable drainage measures are ones which avoid adding to flood risks both at a development site and elsewhere in the catchment by replicating natural drainage processes. SuDS work by slowing and holding back the water that runs off from a site, alleviating flooding and allowing natural processes to break down pollutants. More systems and biodiversity net gain requirements which comply with the best practice guide and coding requirements set out in the ‘Landscape and Nature’ section of this code.
Boundary treatments must be in keeping with the surrounding traditional context. Where boundaries are required to delineate between public and private space they must be complementary to the design of the facade and not impinge accessible approaches to entrances.
Gate piers and gates must complement the boundary treatment, reflect the surrounding context in both design and height.
Historic boundary treatments
Historic boundary treatments must be retained and new openings kept to a minimum.
