  3. 3. There are opportunities in ALL sectors and not always new-build Housing retro-fit challenge (Source BERR 2008) I 80%+ of housing stock in the UK in 2050 already exists I 500,000 houses to be transformed per year at approx £20,000 - 30,000 house for 40 years I 200,000 construction jobs required to support the task I The largest ever UK Engineering Project
  4. 4. Sustainable communities: how many opportunities do we want? Community-scale wind turbine Solar shading Green roofing Fuel-cell bus Waste-to-energy plant Maintained ‘eco-system’ Combined heat and power plant Refurbishment existing dwellings Rainwater harvesting District heating network Smart metering Sustainable drainage system Car re-charging High-speed broadband Ground-source heating Zero-carbon dwellings Community recycling There are examples around the world (even in the UK), get out and see them!

  23. 23. Visitor Centre Taking full advantage of a 54 acre site, HPW created the concept and developed the Visitor Centre to act as a hub for access to: - 26 acre Country park - 6 permanent mazes - Countryside interpretation exhibition - Retail offer A purpose built 4,500 sq.ft. timber framed and clad building. In its countryside setting the centre nestles beneath established trees and oversails two lakes to form a gateway to the visitor attractions and complementary retail operations.
