Very 70's is a Good Thing! It has charm and character, and a strong connection to the exterior from the interior. I would try to just take care of any deferred maintenance on the exterior, and maybe think about a different colored trim. Maybe a browned down forest green? Other than that, the house is great.

The interior suffers from too much wood, as do many cabins. Choosing cabinets in a paint color will help to give the eye a resting place and some contrast. However, your scope of work for your project depends greatly on what budget you have to spend on changes. Minimal budget changes would be to paint the existing cabinets, railings, and get rid of all of the wood furniture for softer upholstered pieces, and maybe a great modern resin dining set like a Saarinen pedestal table and green Panton chairs. You could easily make this into a show place if you concentrate on simple solid color contrasting pieces as counterpoints to the wood.

Is that door next to the refrigerator the front door or the back door?

Well, I just love that place. I suppose it would be nice to have a mudroom. Maybe there's a way to enclose that porch, keeping a lot of glass for the views, but maybe have a place to take off all the shoes and store the outdoor gear.

Thank you so much! And yes, the fridge is next to the front door.

Easiest thing is just to ditch the eating bench and put in a 18"-2' deep breakfast bar along the wall and have people sit at one side and the end.
