Interior design for cottage main living space

Im purchasing an 800 square feet cottage with 3 small bedrooms, one bathroom, and a kitchen/dining/living room combination space looking for inspiration using styles I like to create a cohesive, functional and beautiful space. The main focus of this request is interior design gor the living space. Mood boards are okay but I would also like some renderings of the interior even if not necessarily 3d. Happy to answer other questions. Thanks so much.
