In many northern parts of the world, it is natural to follow a cycle that is similar to how many animals hibernate as the temperature gets colder and the days get shorter. This process is often called cocooning because you build a sort of cocoon around yourself, and only go out when needed.
Your winter cocoon is as individual as you are, and it should meet your needs as perfectly as it can. If you are quieter, you might want spaces that are specially insulated with plush rugs, soft furniture, and plenty hanging on the walls. If you like things to be a bit less low-key, you might want to have a room with a tremendous sound system in place. There are so many options available; you might even need two or three spaces for your cocooning.
More and Less Social
Some spaces are simply built to be social. When you have a group of friends around, your winter cocoon can still feel cozy. It just might be at a lower energy level than during the warmer months. A social space usually has at least one activity that gets people to come over. Then the time spent together can evolve organically based on what everyone wants to do.
Of course, even the most extroverted people need their alone time. Some introverts truly welcome the cooler months, since they can be alone and easily justify it. For some people, spending time by themselves and enjoying solitary pursuits is what happy cocooning is all about.
Indoor and Outdoor Cocooning
It is a myth that every creature that spends its time in a sort of cocoon has to do this exclusively inside of something else. In some cases, your cocoon space can be outdoors, depending on the weather of a given day or night and what you are looking to do in that space. You might even have a couple of spaces set aside for the more sociable or outdoor friendly moments.
When you are indoors, naturally, space has to accommodate the number of people you want to be around. This also varies based on the intimacy level of the space. A “swinger” area can be quite cozy, versus if you are having a few friends over for completely platonic board games or movie nights. The space must complement the activities that will take place there.
Outside spaces, by default, are going to be much larger. However, they do not have to feel large. Darker colors can draw in more warmth from the sun as well as feelings of intimacy. Having a fire table or any other space warmer can also keep the party from becoming a forced cuddle fest just to stay warm. Often, the activities in these spaces are centered on a particular area, or there is just a sitting space in between outdoor pursuits like sledding or building snowmen.
There is no one way to build your winter cocoon. Just tinker with what you like until you get it just right.
