value to you or value when you put your house on the market? it depends on the project. yes, a well maintained driveway and tidy yard will *help* sell a property. elaborate/hard to maintain landscaping won't. many people actually will think 'wow that will take forever/cost a fortune to keep looking like that.' i think more people want easy care as their first priority, and wont pay any extra for an overdone yard. so these days, i'd go all minimalist for resale value. small grass area with automatic sprinklers in areas where expected rainfall will support it, more stone mulch and low water plants in areas that are dry. ticks are a problem and mosquitos as well, so a wildflower border needs to have a defined edge with grass/stone before sitting areas. the nice night lighting no one will ever see when you are selling your house unless its the sort that has its photos taken at night with all the lights on. we've just overhauled our pool area at our vacation home; our theory there is that we want the house to be at all times 100% ready to put up for sale when the day comes that its not fun to own any more. so that $25K won't improve the value of the home, it will keep the home saleable. and we'll get to enjoy it til then.

I understand going with the grey since it is an 80's style house. You could also do bright bold colors. I do not know if that is your style. I have attached a quick rendering of the gray scheme you mentioned. I prefer light colors above dark colors. This keeps in theme with the sky and earth. Makes the house seem more grounded. The dark entry also draws your eye to it especially with the light coming from the other side of the house. I have also attached a quick rendering of a blue scheme. It looks like you are on a beach and I thought this would blend in with the surroundings. If that is what you are seeking. Hope this helps.

Sorry, don't think it fits, The prongs on the light give it a more circular shape but you have this over a beautiful oblong bench. Always rectangular or oblong over rectangular. And the dark ends of the bulbs will create shadows, not so good in a work space. Used to work in lighting for a few years and it always comes down to what makes you happy. I would have tried to steer you in a different direction, Hope this helps.

So if I want to include sustainable things in my house, where should I start?
