Significant uses of nanotechnology have surfaced in the last few years with applications for architectural design and the construction of built environments. The programme contains several interviews with experts.

Austin Williams explores the difference between fixings and fastenings with a focus on nails and screws.

Filmed entirely on location, this programme looks at the increasingly common phenomenon of vertical gardens, or living walls as they have become known.

We explore the hazards of moisture penetration in external walls and ways to avoid problems.

The London Development Agency (LDA) and the Homes and Communities Agency (HCA) have launched a new, mapped database of London's brownfield land called The London Brownfield Sites Database (LBSD).

Whether the ground floor of a house is suspended or filled, it will include either a solid slab or an oversite layer of concrete laid on compacted hardcore directly on the ground. Both hardcore and soil are potential sources of sulfates and other chemicals harmful to concrete. This programme investigates the hardcore components and soil conditions likely to contain sulfates, explains how concrete is affected by sulfate attack and looks at methods used to prevent such damage.

In this programme we discuss the tell-tale signs of a wood-boring insect infestation and describe how to tell the difference between the four main types of wood-boring beetle common to the UK.

The replacement of the old British Standard BS 6651 with BS EN 62305 will have a significant impact on the design and installation of lightning protection structures. This programme explains why the new standard has been adopted and discusses its key points. The procedures associated with the new standard are examined, while Surge Protection Devices (SPDs) and Lightning Protection Zones (LPZs) are explored in detail.

We start by hearing how the UK's network of 200 fundamental benchmarks all stem from a single 'mother' benchmark at Newlyn in Cornwall. We show how the network expanded and we learn why now, in this highly technical modern age, the humble benchmarks' days are over.

This programme takes a look at the current state of ventilation in schools.

The Royal College of Music in London is located in the cultural quarter of South Kensington, an area crowded with museums, concert halls and academic institutions.

In this programme we define CHP; the fuels that can be used to power the plant and the basic principles behind the technology and why CHP is different from co-generation plants.
