North Ayrshire Council
Draft Supplementary Street Development Guide

Welcome to this site where you will find information about our draft Supplementary Street Development Guide (SSDG) for North Ayrshire. 

Thank you for visiting the site. The consultation on the Street Development Guide is now closed.


In 2010 the Scottish Government introduced the Designing Streets policy that puts place and people before the movement of motor vehicles. Subsequently a National Roads Development Guide was created to assist developers with the technical aspect of street design.

However, given the unique character of North Ayrshire with its coastal towns, rural areas and islands we sought to develop a street design guide that will be supplementary to the National Roads Development Guide. The Supplementary Street Design Guide (SSDG) will replace the existing North Ayrshire Roads Development Guide and is aimed at assisting developers to meet the requirements of designing streets within North Ayrshire.

North Ayrshire Council’s new SSDG has now been drafted and is available for stakeholder consultation. The new guide takes account of national and regional policies and guides, analysis and feedback received during the initial consultation.


The new guide provides guidance on street design principles and technical standards for residential areas in North Ayrshire. The guide sets out a hierarchy of use for streets with needs of pedestrians and cyclists being prioritised.

The guide aims to promote sustainable streets through design that will encourage high-quality environments.

The guide is intended to provide guidance on how to create a street, construction details, construction consent procedure and adoption process, and provide clear sign posting to other guidance documents including ‘Designing Streets’.
