This document is a product of the agencies taking part in a Temporary Technical Committee on building rehabilitation. The upgrade and rehabilitation of substandard buildings to provide capacity for sheltering displaced and vulnerable people has been ongoing in Lebanon since 2007, and is a significant part of the shelter sector’s response to the Syria crisis. The creativity and adaptability of agencies working in different social and economic contexts in Lebanon is a sectoral strength, however the standardisation of principles and minimum shelter standards is required to ensure a quality service to beneficiaries.
