Making Walls from Photos
First, correct any perspective distortion. I use a grid (at 50% opacity) and try to get the bricks in horizontal rows. Remove anything you like with the rubber stamp tool. In this photo, I decided to make a lamp from bryce primitives, so I deleted it from the image, including its shadow! Then, make a grayscale image of identical size and adjust levels so that grayscales represent height. Plan to set the opacity slider in bryce such that black becomes transparent, for any window or door openings.

Plan wireframe
Correct any perspective distortion. Remove anything you like with the rubber stamp tool. Here I decided to make planter boxes, steps, awnings, handrails and lamps in bryce. Goodbye until later! Again, make a second identical size grayscale image and adjust levels so that grayscales represent height. Here I wanted the frames around doors and windows to protrude, so i lighten them in the grayscale image. Then flip X for the other side.

Now, build the bryce parts. Make a terrain object of appropriate size (here, used 2048x2048). Load the grayscale height map. Immediately load the matching color image as the texture. Leave the mapping to parametric and it should overlay exactly with the height map. Generally I also set Ambiance to zero. Since we have transparent windows, provide each with a thin pane of Bryce glass sandwiched in the middle. Add protruding items such as porches, steps, lamps, awnings, planter boxes, etc.
