Would like to know if anyone has every used or heard of a company called Heartwood Homes. They are a bit like the Griffner Coillte houses. Visited both show houses - Heartwood and Griffner Coillte, very impressed with both, trying to decide whether to go for one of these house - obviously the price is a big factor. We are trying to decide between these or block build - by the time you have everything installed and ready to walk into would there be much of a difference price wise? We are looking for a highly insulated house, very good windows, solar panels and possibly aerothermal heating. Would like advice if there's anyone listening?
