I spy with my little eye, something beginning with 'p'... it's sturdily solid, terrifically timbersome, brilliantly beautiful, and awfully affordable, too!
Answer: a deTerra pilaster!
We stock six pilaster types in a range of sizes (thickness and width varies but height is fixed at 870mm to match our cabinets, for your convenience); these wooden items make fabulous, decorative finishing touches to your cabinet run.
From ornate to simple, we have a pilaster pretty enough for any kitchen; and we can paint, lacquer or oil these as required (you're also welcome to order a simply sanded version and finish yourself!). We can also add a nifty edge profile - y'know, if you're so inclined.
