A build-out is a section of kerb/footway extended out into the carriageway on one side only to narrow the road. They can reduce crossing distances and improve visibility for pedestrians. If the space is available, a gap can be left between the pavement and the build out to form a cycle bypass.
Build-outs can be difficult to achieve where there are many private driveways restricting their positioning.
A build-out is normally furnished with bollards and dropped kerbs/tactile facility and usually costs approximately £12,000.
All costs stated are for guidance only.
Figures provided are estimates and are reviewed annually, with all costs subject to a site survey assessment.
