Interior · Exterior · Harmony

A house becomes a home
in the details nobody
photographs.

Phenomenon Design works inside, outside and in between — for families building once, and for the hoteliers and developers who build for a living.

Now showing — Villa Kamen · Boyana, Sofia

The practice

One studio for the
whole of a place.

Most projects are handed between an architect, an interior designer, a landscaper and a contractor — and lose something at every handover. We hold all of it: the plan, the palette, the garden, the light at seven in the evening, and the joinery detail that decides whether a room feels finished or merely furnished.

We work on a small number of projects at a time, in three studios that share one material library and one set of standards. Whether it is a family house, a boutique hotel or ninety apartments, the same principals stay on it from first sketch to the day the doors open.

Three studios

Divided by discipline. Never by project.

Selected work

Places we have finished.

Filter by studio or by who we built it for. Open any project to see the brief, the scope and what changed.

Harmony

The same room.
The same light.

Nothing structural moved here. We repaired the plaster, corrected the colour temperature of every lamp, replaced three pieces of furniture and left the parquet exactly as it was. Harmony is mostly subtraction.

Before After

Material library

Everything is chosen in the hand first.

Two thousand samples, catalogued by how they age rather than how they photograph. Touch a marker on the board to see what we specified on this project.

How it runs

Five stages, one team throughout.

The studio

Twenty-two people.
One material library.

Phenomenon was founded in 2008 above a joinery workshop, which is still where we prototype. Today the studio holds architects, interior designers, a landscape team and two full-time makers who build the details nobody can source.

Every project has a named principal who is in the room at the first meeting and on site at handover. That is the whole management philosophy; there is nothing else to it.

Tell us about the place.

We take on nine projects at a time, so the first conversation is honest about whether we are the right studio and whether the timing works. No charge, no pitch deck.

One of the principals will write back within two working days — with a straight answer about fit and timing.

What Yanev Group actually builds

Everything above is
a sample. Here's what
we'd build for you.

Phenomenon isn’t a real practice — it’s a sample of how the system could look for an interior or exterior design studio, an architect or a fit-out contractor. For a real client, here’s what we connect and take ownership of.

01Brand & presentation

A look with actual attitude — the thing that makes a car owner choose you over the cheaper shop down the road.

02Website & slot booking

A site like the one above — built, hosted and kept working, with booking requests landing on a phone that rings.

03Build photography & reels

Your work shot properly and cut into the short video that sells this industry better than any brochure.

04Google, Maps & reviews

Found for "wrap", "tuning", "detailing" near you — and a review profile that keeps growing instead of stalling.

05Instagram, TikTok & ads

The channels where car people actually live, posted to consistently and connected to the same booking system.

06Ongoing management

One team responsible for all of it after launch — not a one-off build that's left to go stale.
