Larkrock Green Homes is a Dublin-based company specializing in deep energy retrofits and new build projects, primarily serving the Leinster region. Founded in 2017 under the registered name Lark Rock Limited, its principal business is managing comprehensive residential energy upgrades and building works, often in tandem with Ireland’s Sustainable Energy Authority’s “One Stop Shop” grants. Larkrock employs a direct staff of 16 and relies on a substantial network of more than 100 subcontractors.
The organization’s activities cover a wide range: upgrading insulation, improving heating systems, installing renewable energy technologies such as solar panels and heat pumps, and executing significant renovations that sometimes involve redesigning internal layouts. Notably, Larkrock delivered a full retrofit of a 1949 Templeogue semi-detached home, cutting its annual energy consumption from 31,788 kWh to 8,553 kWh and reducing carbon emissions from 6,714 kg to just 309 kg per year. This project involved upgrading windows, rewiring, replumbing, and integrating solar and air-to-water heating systems.
Beyond retrofits, Larkrock has constructed 55 “A-rated” luxury apartments and 83 houses in Malahide, maintaining a focus on high energy ratings and sustainable building. The company gained public attention through its role in RTÉ’s “Room to Improve,” where it led challenging home transformations, merging energy efficiency with extensive building works.
Its expertise spans insulation, heat pumps, ventilation, solar PV, windows, doors, and extensions, managing every stage from energy assessment to project completion.
