PB hotel design editorial

Right on the waterline at St Mawes, where the Fal estuary opens toward the Roseland Peninsula, a whitewashed Edwardian building has spent most of its life watching boats. Reopened in 2015 after a thorough restoration by owners David and Karen Richards, The Idle Rocks is one of Cornwall's more precisely considered small hotels — twenty-three rooms across three floors, the building's granite harbour wall forming its literal foundation, the terrace set directly atop it with all-weather wicker furniture and market umbrellas angled toward the anchorage. Interior designer Alexandra Medhurst drew the rooms in a palette that acknowledges both the maritime setting and the domestic register the Richards family wanted to preserve. Sisal carpeting and linen curtains carry most of the weight; individual rooms push further with ikat-print upholstered headboards, wicker Lloyd Loom-style chairs, and pops of burnt orange cushioning against grey-and-white striped bedding in the upper-floor attic rooms, where sloped ceilings and casement doors open to the water. The restaurant is the most deliberate space — textured limewash walls, faceted timber pendant lights, and velvet button-back dining chairs in cobalt and mustard framing a long communal table, blue-and-white transfer-print crockery on the surface, the Fal estuary filling every window. The effect is closer to a well-loved private house than to a coastal hotel working too hard at its own atmosphere.

"we called in for cocktails,it was a sunny day,but there wasnt any decking furniture out,the bar staff moved a table and 3 comfy chairs outside,where we enjoyed almonds,olives and lush cocktails,OK not the cheapest in the world,but high end ingredients in such lovely surroundings with attentive staff,worth every penny."

"3 of Cornwall’s plus size models/sweatboxes decided to go for a meal together and wanted something of a higher caliber. From the moment we walked through the door we were met with a friendly welcome, a beautiful warm inviting restaurant and then a front of house team who were fantastic. I’d ordered a rosé wine which made the other 2 very uncomfortable but the banter was short lived when the starters arrived. The food was out of this world, we tried everything we could off the menu, me more so, as I thought one of us (not me) was paying for the lot. Every course was cooked perfectly and having Harrison come out of the kitchen to describe the dishes before we ate them went above and beyond. Highly recommended to all!"

"Without a doubt, the best experience we've had in recent years visiting The Idle Rocks for dinner. Delicious food. Spectacular service. We found a cozy restaurant with a different, more welcoming and pleasant atmosphere. A completely different welcome, we felt truly welcome and special. Finally, we would like to thank the chef for the delicious food and Tiago, whose calm and welcoming attitude made the food and the wine he chose for us taste even better. Thank you to the whole team."

"We went here for a simple drink before heading home. The hot chocolate was tepid and tasteless and the mocktail was equally insipid. The waiter seemed to think himself superior, as may do these days. Shame for a place like this I was surprised. Maybe we looked a little scruffy that day but don’t judge your guests in this way."

"myself and my husband have been coming to the IR since 2018 and we return each year. we always tend to stay in Room 2 as it's our favourite with the stunning views and huge bathroom with the bath in the window. this stay was another wonderful one. always so well looked after by the Idle Rocks team. Breakfast each day was 10/10. we sadly didnt get to enjoy dinner in the restaurant as it was closed for a few days but we did enjoy a lovely meal at the St Mawes hotel on the night we were due to dine at the IR. we truly love the Idle Rocks and it's one of our favourite places to be. so im sure we'll be back again in 2026!!"
