Cold temperatures, unpredictable weather, and shorter daylight hours all complicate proceedings. For a garden room business like Downland Garden Rooms, winter doesn’t mean putting projects on hold – their clients still need their builds completed on schedule.Laying concrete foundations in January? That would mean extended curing times, frost protection measures, and the very real possibility of weather delays that could push everything back. For a business managing a constant rotation of projects, that’s not ideal for them or their clients. Plus, concrete poured in winter needs more aftercare to prevent frost damage which adds further complications. The solutionWe worked with Downland Garden Rooms to design and install a 4″x 2″ C24 treated joist base with a double-ring beam configuration.Our installation team arrived on site and had the entire foundation completed before midday. We installed the 1250mm ground screws, each positioned to support the building’s load points.The ground was hard and muddy, but it’s no issue for ground screwsThe weather wasn’t great, and the temperature wasn’t ideal. But ground screws don’t need sunshine or warmth to perform.Because ground screws are ready to bear weight immediately, Downland Garden Rooms could proceed with the build without worrying about overnight frost damage.Ground screws are immediately load-bearing, meaning the base and garden room can be fitted immediatelyThe customer will have their garden room ready to go by spring, which is exactly when they want it for. A smart move to beat the spring-summer rush.The resultsQuick, precise installation in challenging winter conditions kept Downland Garden Rooms on schedule and their client happy. Ground screws are ideal for winter construction, a practical benefit when you need to build off-peak during the colder months, when things are quieter and potentially even cheaper. 4″x 2″ C24 treated joist base with a double-ring beam configurationThis is what a reliable partnership looks like.
