The studio
Built for slow, exact work
We opened Arch & Oak in a former piano workshop on Linden Mews in 2021: one long, light room with oak floors, arched mirrors and windows on two sides. Nothing loud, nothing rushed, no music you have to shout over.
Everything you need after class is already here, so you can go straight on to work, brunch or the school run.

Your first class
A few things worth knowing
Arrive ten minutes early
We’ll set your reformer up, show you the springs and ask about any injuries.
Grip socks, please
Required on the reformer for safety. Intro offer clients get a pair free; otherwise they’re £12 at the desk.
Wear something fitted
Leggings or shorts and a close-fitting top. Avoid zips and buckles, which can catch on the straps.
Eat light
A small snack an hour or two before is ideal. There’s filtered water on tap.

★★★★★
I’d never been near a reformer and was dreading it. Imogen had me set up in two minutes and checked on my dodgy shoulder all class. Three months in, my back pain is basically gone.
★★★★★
Tom’s Saturday Sculpt is the hardest 50 minutes of my week and I wouldn’t miss it. Small classes mean you actually get corrected.
★★★★★
Did Prenatal with Priya from 16 weeks right up to 37. Felt looked after the whole way, and came back for postnatal privates.
FAQ
Good questions
Can’t see yours? Our assistant answers in seconds, any time of day.
Ask the assistantI’ve never done Pilates. Where do I start?
Book the intro offer (3 classes for £45) and start with Reformer Foundations. Most people move on to Flow after two or three classes. If you’d like extra confidence, an intro private (£65) is a lovely way in.
I have an injury or back pain. Can I join?
Often, yes, but please check with your GP or physio first and let us know when you book. We recommend an intro private (£65) so your instructor can assess you and show you safe modifications before group classes. We can’t give medical advice.
Can I come while pregnant?
Yes, from 14 weeks, in our Prenatal Reformer classes. Please get the go-ahead from your GP or midwife and book an intro private with Priya first; after that she’ll approve you for Prenatal classes. If you’re already a regular, talk to us as soon as you’re comfortable sharing your news.
What’s the cancellation policy?
Cancel at least 12 hours before class and your credit comes straight back. Later cancellations and no-shows use the class; Unlimited members are charged £10.
Do I need grip socks?
Yes, they’re required on the reformer. Intro offer clients get a free pair; otherwise they’re £12 at the desk. Any brand of grip sock is fine.
Are men welcome?
Very. Around a quarter of our regulars are men, and Sculpt in particular is popular with runners and rugby players.
Can I freeze or share a membership?
Memberships can be paused once a year for up to four weeks. Packs and memberships are for one person and can’t be shared.
