LASplanning configured a 2019 house extension to better utilise former garden ground and most recently (2023) to enhance the overall sustainability of the house and reduce its running cost.
In addition to the physical interventions and design concept, coordination of funding sources was undertaken, through the support of Home Energy Scotland.
The below summary outlines the key project components in switching to a combination of renewable technologies to provide power to the family home.
Summary Data Sheet – Project/ Energy Timeline (detached 5 bedroom home) – all data drawn from client’s personal records to date and may vary depending on property and personal circumstances
1. Detached modern home built circa July 2010
- 120m2 total size
