Winchburgh (Historic Project)
West Lothian

3,450 residential units together with associated retail, commercial, educational, community and recreational uses


The Winchburgh development is one of the UK's largest mixed use projects located just south of the M9 and approximately 11 miles west of Edinburgh City Centre and 4 miles west of Edinburgh airport. Sigma's Chief Executive, Graham Barnet, is one of the founders of the development and has had a 12 year connection managing the landowners interests and working on the development management piece for Sigma's client Regenco Limited.

The planning and design process began more than 10 years ago, and the release of planning has now commenced the development of 3,450 residential units together with retail, commercial, education, transport links, infrastructure and other land uses over a period of 15 to 20 years.

Sigma's development team managed the negotiations on behalf of Regenco Limited (the developer and major land owner) of the Planning Agreement with West Lothian Council in relation to the Council's "minded-to-grant" Planning Permission for the implementation of a 3,450 housing unit Masterplan.

Planning in Principle has now been issued by West Lothian Council, following the successful negotiation of the Section 75 agreement. The development includes 3,450 residential units together with associated retail, commercial, educational, community and recreational uses.



Sigma's land and development team have managed all stages of the development process from negotiating planning to the procurement of contractors to carry out enabling works and preparing serviced sites.

Sigma's management role includes:

  • Preparation of development briefs
  • Development appraisals / cash flows
  • Marketing development plots
  • Negotiating land sale agreements with housebuilders
  • Delivery of affordable housing
  • Infrastructure procurement
  • Negotiating planning and development control
  • Site preparation
  • Feasibility studies
  • Land remediation
  • Market research and analysis
  • Community engagement
  • Managing consultants and contractors

The first phase of the Winchburgh project will consist of 550 residential units and will be spread over 5 separate plots including 91 affordable housing units. The first plots were secured by Barratt and Miller homes in October 2012 and they are well underway on the construction of the first 180 homes. Sigma carried out all site enabling works to allow both housebuilders to commence development on site and the first house occupations took place in April 2013. In addition to Miller and Barratt, Sigma have concluded contracts with three further national housebuilders; Taylor Wimpey, Bellway Homes and Stewart Milne all of which are under construction and selling well.



Site servicing and delivery of infrastructure was procured by Sigma on behalf of the land owner Regenco. Infrastructure to be delivered for the first development plot includes:

  • Site preparation including the removal of 70,000m3 of soil
  • Construction of foul and surface water drainage connections
  • Construction of SUDS (Sustainable Urban Drainage Systems)
  • Provision of utilities to site boundaries
  • Landscaping

Strategic Infrastructure will also be required in line with the Masterplan which will include the delivery of a new motorway junction on the M9, new distributor roads, neighbourhood centres, strategic landscaping, schools, town centre retail, community facilities and upgrades to mains services.


Affordable Housing

As part of the first phase of development Sigma managed the delivery of 91 affordable housing units. This will be made up of the transfer of serviced land to West Lothian Council for 41 homes and the construction of a further 55 units.
