Joséphine Lecoufle-Vinet · Founder
Home is everything
An eye on the past, a passion for design.
Joséphine grew up in characterful homes filled with quality pieces — her father was an antique dealer. That eye for craft, history and colour runs through every JLV Design home: simple, elegant and functional, and always tailored to the people who live there.
Whether you’re decorating a new home, starting a room makeover or buying new furniture, turning a vision into reality can be tricky. We make it feel easy — and genuinely enjoyable.

Why JLV Design
What clients notice first.
Eleven Best of Houzz awards for client satisfaction come down to four things.
- 01
Colour, confidently
Bold, considered schemes matched to the light in each room — rooms that feel distinct, yet flow as one house.
“…beautiful colour schemes which we would simply not have discovered or been bold enough to choose without her on board!”
— Chloe Hillier, Houzz review - 02
Calm in the chaos
Measurements, orders, deliveries and trades coordinated for you, so renovating feels exciting rather than overwhelming.
“She brings a sense of calm to the chaos of renovations…”
— Abhi Finn, Houzz review - 03
Your home, not ours
Joséphine listens first, offers several options, and stays open to your ideas — the result reflects how you live.
“Full of great ideas and always open to new ones.”
— Houzz client, Houzz review - 04

Re-use what works, refinish rather than replace, and spend where it shows. Ideas across a range of price points.

Questions
Good to know.
What does JLV Design do?

Founder Joséphine Lecoufle-Vinet offers hourly design consultations, room design schemes, colour advice, bespoke joinery design, home styling and staging, and full-scale design, sourcing and project management for renovations and extensions.

How much does an interior designer cost with JLV Design?

Can you work within my budget?
Yes. JLV Design works within your budget, whether it is a single room makeover or a whole new home. Joséphine offers options across a range of price points, re-uses good existing furniture, sources vintage pieces and suggests refinishing instead of replacing — for example, spray-painting a kitchen rather than buying a new one.
Which areas of London do you cover?
We are based in Muswell Hill, N10, and work across North London, including Crouch End, Highgate, East Finchley, Hampstead Garden Suburb, Alexandra Palace, Harringay, Stoke Newington, Southgate, Arnos Grove, Barnet, East Barnet, Enfield, Borehamwood and Willesden.

Do you offer online interior design consultations?
Yes. Online consultations work by video call: you share photos, rough measurements and inspiration images, and Joséphine gives advice on layout, colour and furnishings. They suit clients outside North London or with busy diaries — one recent client in Scotland said the online sessions finally made the whole space work.
