Over the weekend we lit our first official fire of the season. The mornings and evenings are now consistently chilly, and I'm not leaving the house without at least a coat or jacket for a while. It's this time of year when my focus on beach and pool houses shifts over to mountain lodges and retreats. Something about being surrounded by dramatic wooden beams and fireplaces along with fur throws and flannels seems to lessen the harsh reality of the cold months ahead. This Big Sky, Montana house by the design team Lucas Studio holds all these warm elements and so much more.
