Our home built in the '60s uses cedar lap siding. 10 years ago when I built my shop, I had the contractor use Hardiboard. He matched the pattern and you can't tell the difference. Last year we had a bumpout built on our kitchen. Again, we used the same contractor and I asked for Hardiboard. He cut the siding in so well, the average person can't tell where the Hardiboard starts and the cedar siding ends.
