Renovations · extensions · whole homes
Renovating or extending is a long run of decisions. We take them on with you — working alongside your architect and builder, or introducing trusted trades we know — so the finished home feels personal, cohesive and calm to live in.

Full interior design means one designer looks after your home from first idea to final cushion: layouts, colours, materials, lighting, bespoke joinery, furniture sourcing, ordering and coordinating the trades. JLV Design offers this for renovations, extensions and whole homes across North London.
Every room has its own character, but the house flows as one — colour, materials and joinery are planned together.
Clear options at each stage, and someone to handle measurements, orders and contractor coordination.
Suggestions across a range of budgets, and clever efficiencies — re-using good furniture, refinishing rather than replacing.
The process
A call to understand your home, how you live, your timings and your budget.
A visit to measure, photograph and agree the brief and scope.
Mood boards, layouts, colours and materials — with options, and room for your ideas.
Joinery drawings, lighting plan, specifications and a schedule of items to buy.
Ordering and coordinating with your builder, decorators and suppliers.
The finishing layer — art, accessories and soft furnishings — so it feels like home.
Fees are quoted after a first conversation about your home and scope.

FAQs
Yes. Many JLV Design projects are collaborations with architects — including Nikki Blustin, Johanna Ahrberg Jackson and Enbee Architecture + Design. The architect leads the structure; we look after colours, materials, lighting, joinery and furniture.
We coordinate with your builder, decorators and suppliers on the design side — measurements, orders, deliveries and site questions — and can introduce trusted trades if you need them.
It depends on the build. Several of our extension projects ran over about a year from first plans to final styling.
