I love your fireplace. I would not alter it. The door and the floorboards draw your eye straight to the fireplace. I wouod definitely alter the light fittings. I would have the tv on the dining room wall to the right of the arches. I wouod have one lounge on the window wall opposite the tv and a chair in the corner if there is enough room. I would have an eyecatching wing back chair to the left of the fireplace opposite the dining room and white lacy soft curtains softening the window wall. To the left of the fireplace near the dining room arch you could add some interesting decorating piece. I would concentrate on making the fireplace wall the focal point of the room and the tv corner a secondary focal point that is soft and relaxing. You could trow down a couple of beautiful, thick, soft floor mats to soften the brick and provide a texture contrast. Overall, I love the room, it has character and strength, its not boring and mundane. Good luck! I hope you find something that suits both you and hubby

Painted Murals done professionally are extremely expensive dependant on size wall texture and the preparation needed prior to being painted. If the space is small you could try and do it yourself but if the pace is larger they really need to be done professionally. Have you considered using a large photgraphic print instead. You can pick any landscape or image you like, you can get them done on canvas or in a wall paper and in almost any size. eazywallz has some great examples

my suggestion are based on the fact that mum and dad are usually at the house alone and aims for simple two person accommodation that can be rearranged to suit a crowd...the kitchen cabinets are the only fixed objects in the room and include a tall pantry, base cabinets and/or drawers with open shelves and wall cabinets and space for several people to work side by side with a small extendable dining table, two chairs and a bench seat (also used as a place for newspaper and lamp etc behind the recliners)...a patio with big table for outdoor eating under the shade of the tree with extra bench seats that can also be used inside... there's space for a small divan or night and day lounge with a wall hung tv and the corner bedroom door allows for much better circulation space in both the living and bedrooms with preferably a sliding glass door for indoor outdoor connection with or without the original front door and, based on the size of king single beds, there's no other arrangement that would allow both beds to have a view to the lake and there's just enough space for a biw, small desk and two chairs

Am so pleased for you, Lucy. What a lovely home and it very much suits its gorgeous setting. Love, love, love the use of timber, and all that glorious light. I now also have a serious case of dining chair envy. And the view! No wonder you’re (rightly) pleased. Health, happiness and many, many years enjoying the fruits of all your hard work to you and yours And to all the lovely Houzz community members who helped Lucy, and myself, cheers you wonderful people
