Higher costs, less benefits - Why the enhanced social housing leasing model is a bad deal
The outgoing Fine Gael government devised an off balance sheet scheme to deliver social housing, but will it deliver value for money? Mel Reynolds crunches the numbers and finds the scheme may almost double the cost compared to a direct build – with no asset left once the lease ends.
Strong and stable - East Sussex home with a striking farmyard inspired design
While this striking new larch-clad home in rural East Sussex ultimately received the backing of the local planners, there was just one catch: it had to meet the passive house standard before its owners could move in.

The PH+ guide to air source heat pumps
As electricity supply from renewable sources continues to grow, and electricity grids gradually decarbonise as dirtier fossil fuels are phased out, heating homes with electrical technologies like heat pumps starts to make more sense. And in the mild, temperate climate of Britain and Ireland, air source heat pumps are particularly suitable — especially as new build standards of energy efficiency continue to tighten, meaning new homes need less and less energy to achieve comfortable indoor temperatures. But how do air source heat pumps work, what types are there, and how much do they cost to run? Our in-depth guide attempts...

The PH+ guide to airtightness
Once poorly understood by the mainstream building industry, airtightness is now increasingly seen as one of the most crucial objectives on any building project. Not only is it vital for energy efficiency, it’s also key for thermal comfort and for protecting a building’s structure from dampness and mould. In this comprehensive guide to airtightness, we look at why it’s so important, how exactly it’s measured, and most importantly, how to achieve it on site.
