We were also interested in having handleless drawers and cupboard doors for our kitchen. The kitchen company we used had a sharknose handleless kitchen in their showroom and we liked the clean lines of it.
But they told us handleless drawers were more expensive because there were more work involved to make the bevel.
To stay within budget we chose to upgrade to Blum softclose for all drawers and have small handles on drawers. For the overhead cupboards they made the door 20mm longer so you can open them with the overhang.
We're pleased with the end result.
