Flooring Tile - New Tile in Foyer

My wife and I have done some remodeling and want to install ceramic tile in the foyer. Currently the foyer and entire first floor consists of 3/4 inch oak hardwood sitting on a subfloor that is 13/16, 3.5 inch planking which sits on 2 x 8's. The house was built in the 50's.

My plan is to remove the oak, resecure the planking with wood screws and install 1/4 inch hardy backer, the use thin set for the tile. I don't want to build up the underlayment too high because I will have issue with the adjoining oak, two adjoining rooms, as well as the front door. Does this make sense to you professionals?

Thanks,

13/16 + 1/4 = 17/16 or 1 1/16" this might work. Be sure to use latex medified thinset mortar both under the hardie backer also screw to subfloor, and to attach the tiles. One of the "flex" thinsets would be best.
Years ago I also ran into a "flex" grout additive.

Be sure to protect your hardwood floors from the thinset and grout. A perimiter expansion joint around the tile would be a good idea.

thanks for the update, what do you mean by perimeter expansion joint???

one more questions - flex thinset. I've used laticrete in the past with there additive for bathroom floors. Would they carry??

perimiter expansion joint: in this senario , don't grout the space between the tile and the hardwood floor. If any grout happens to get in there just scrape it out before it dries.
Use 100% silicone caulking to fill the gap. This will allow the wood floor to expand and contract with temp. and humidity changes in the house without pushing against the tile and causing it to buckle or crack.
----------------------------
"flex" type thinset and grout could either be sold that way factory made in the bag or could be a liquid admixture to be added to regular thinset or grout. Since I don't have catalogs from various companies in front of me I don't know which is offered by whom.
Most major companies will offer a "flex" type thinset to be used over wood substraits.
