Shaded well and I am too cold

I live in the woods and our whole beach house is shaded by trees.

When I first bought the locale I thought this was a nice thing.

I liked the system of the leaves falling and decreasing colors right by our window. I also enjoyed the thought of privacy. Well, the trees have been nothing but a pain. I am consistently raking, picking up sticks and maintaining our lawn. Also, the trees block myself and others from sunlight. In the Summer our beach house is chilly chilly consistently. The trees totally shade the home. It feels love it is 50 degrees inside our beach house and outside can be in the 80s. I consistently want to run our heating equipment, no matter the time of year. My fiance refuses to run the gas furnace when it is hot outside. I guess every one of us bought the gas furnace to moderate us when every one of us are cold. I am chilly a lot in the summer. The Summer afternoons drop in temperature as well. The chilly afternoons make it that I have to run our heated blanket. I also don’t want to allow the chilly outdoor air to come through our windows. So the same stuffy indoor air conditions stays in the beach house all year. Heating the beach house is not even simple in the winter. The beach house is important and chilly cold. Getting the gas furnace to not leave chilly spots and rise to the ceiling is impossible too. I do save money with no AC, but the gas furnace makes up for those savings. I particularly should cut some trees down to get some sunshine access.
