I agree with you the pillars are unfortunate. The replacement tiles will stand out no matter how close they come to matching so you're better off making sure they are clearly different so the gray one is better. Putting busy mosaic tiles could look nice but will interrupt the flow between rooms which I'm guessing is your problem with the columns in the first place. You will need to create a dextrous solution to tying into the 2x4 wall on the left side but I think it can be done tastefully- maybe beveling it back once you get past he end of that wall.

Hi Please disregard the attached plan (not part of this house), sorry for confusion Matt

Are you standing in a rowboat when taking the picture? Lots of humidity, I guess. Try this in your minds eye: A tall shrub at each deck column below, so the wheelbarrow and dogs and kids can still go beddiebye between them, and continue along the foundation walls as well. You can mix the different plants, but if you choose to, I would suggest 3-5 of the same before introducing another. The lilac, of course, will be the most fragrant; and the shadblow the earliest to bloom. Lilac (Syringa), Shadblow (Amelanchier), Crape Myrtle (be careful when selecting these just by color, as some have a mature height of 2' and others have a mature height of 20') and the Crape Myrtle do not do well up north, if you are on the coast of Maine. Underplant these beauties with groundcover (a flagstone path for the wheelbarrow access) and low flowering shrubs or tall grasses will add nice color and texture for all the passing boatmen to view and smile and wave to you ON DECK above. Ask at the auto supply store if there is a product to wipe onto your railing to prevent fogging of your "wind shield". (as well as your telescope lens) Looks like a great spot for morning coffee and evening Dewars. cascio.offsite@gmail.com

Wow! What an incredible view you have! I think you first need to frame it out. I would suggest changing out the carpet with hardwood floors with a worn or weathered look. Definitely get rid of the plastic and replace with white base moulding. Next I would paint the walls a color in the pale grey or grey/blue family. Next, I would suggest some crisp white sheers to frame each window. In the pictures, it looks like the Windows on the right are two windows wide. If so, I would also place panels in the middle of those 2 windows to continue framing the view. These are for decorative purposes only and not intended to distract from the view. It looks like there is a big space between two of the windows. I would locate a large architectural piece to place on that wall to add some interest. Remove all the small items from the window ledges. Finally, I would love a round table in that space. Good luck with your reno!
