Hi we need major curb appeal help! We are able to change the siding, we can paint and change the eaves or gutters, the windows have to stay in place but we can change the style or add grills etc... The roof stays (Timberlane Shakewood color) and our door is going to be moved. We purchased a 6 lite craftsman door. It will go where there is an existing window and will face the driveway and street. We do a lot of gardening so we were thinking of a cottage or bungalow look. We like the look of cedar shake siding and we also think a pergola in the front would help break up the space but would love any drawings or advice to help us visualize a changed look.

I think its beautiful. It adds warmth and charachter. I think you should leave it but paint the rest if the house
