Thank you! A: Roof is architectural asphalt shingle. Wood shingle is white cedar pre-dipped in bleaching oil. Wood trim, lattice and columns are red cedar field finished with a mix of bleaching oil and weathering stain. **Q: I've been looking for a front door like this! Who makes it?** *(in Photo Questions)* A: This was an existing historic door that we kept and had a custom glass lite made for it. **Q: Hardwood Floor** *(in Photo Questions)* What kind of hardwood is this? A: Bingo **Q: This question is not a new one. House color. Is it a brown grey?** *(in Photo Questions)* It is difficult to come up with the paint color from a printed photograph so says my paint store manager. If any clues could be given it would be greatly appreciated. Just love this house, and we have a old farmhouse to paint this summer. Thanks so much. A: This is a pre-finished fiberglass clapboard product by a company that we believe is no longer in business (Tecton) - so not a paint color, unfortunately. **Q: Depth of porch including handrails? Thanks!** *(in Photo Questions)* A: 8' from face of house to face of porch skirt **Q: House color** *(in Photo Questions)* This place is tight! Can you post the paint colors you used, please?
