Some homeowners will begin the porch project with a clear thought on location. For a home in desperate need of some curb appeal or rehabbing, the front porch may be a no-brainer. For others, the porch might be built over an existing deck in the back of the home. But this big investment deserves a little location consideration and can be subject to limitations. Size limitations or not, nothing makes a first impression quite like a front porch or that of a covered porch.
