Ok, Graemme, I've been following along the progress and really like all the changes you've made, particularly following my idea to use the pull out cabinet doors as opposed to sliding ones.
when I converted mine, I found some inexpensive simple wood knobs at the hardware store and stained them to match the teak doors. while i like your inset grabs much better, I can say that i haven't had any problem running into the knobs, so recessing your cabinets by 3/4 doesn't really seem necessary and of course every square inch is usually needed for pots and pans, etc.
Just my 2 pennies again!
keep showing those renderings and pictures. You've inspired me to add a drop leaf extension to the end of my galley counter. there's never enough counter space for food prep!
