Where we are, and how we think about the work.

Old Boy Design is a small, bilingual web studio based in Houilles, in the Yvelines, a short train ride from central Paris. We work with French SMBs and independent professionals across the Paris region, and with English-speaking businesses established here who'd rather not choose between working in English and working with a locally rooted studio.

A quiet desk setup with paper, a ruler, and a laptop — the working surface behind the site's own layouts.

Our stance

We don't think a website should ask to be trusted on faith. So this one doesn't: the prices are published, the process has real durations, and the standards we claim — accessibility, performance, genuine bilingual content — are things you can check on this exact page, not promises we're asking you to take our word for. We'd rather be a studio that does six things well than one that lists eight and delivers a shallow version of each. If what you need isn't one of the six, we'll say so, and point you to someone who does it properly.

How we work

Fixed scope, before anything starts.

Every project is priced and scoped in writing at Discover — you know what you’re getting before you commit.

Direct contact with the person doing the work.

No account manager relaying messages to someone else — you talk to whoever is actually designing and building your site.

A published process.

Four named stages, each with a real duration, on the Process page — not a vague "it depends" when you ask how long it takes.

Where we are

Old Boy Design is based at 15 Rue de Crimée, 78800 Houilles — in the Yvelines, north-west of Paris, on the line that runs into Paris Saint-Lazare in under 25 minutes. We work with clients across Houilles, the wider Yvelines, and the Paris region, in person where useful and remotely by default.

A quiet street-level detail from Houilles — no faces, a genuine sense of place rather than a stock cityscape.

English and French, written natively in each

A website is either proof or decoration. We build proof.

Un site internet est une preuve, ou un décor. Nous construisons des preuves.

This isn't a machine-translated toggle. Every page on this site is written twice, independently, by the same studio — which is also why you can switch languages on this exact page and read a genuinely native sentence either way.
