IDC Design · Style Library Report

Style Library × the last 30 days

What people in the UK & US are actually posting about interior design right now — mapped against the 18 planned IDC styles. What we cover, what we partly cover, and where the gaps are.

What the research found

A deep pull across social, video and the design press for the window . The signal splits cleanly in two: a designer-taste lane (warm, collected, imperfect, anti-AI) and a louder luxury-spectacle lane (marble, ornate ceilings) that wins on raw views but not on credibility.

Trending styles & themes

Trending video formats

How the content is packaged matters as much as the styles. These are the formats carrying the conversation.

    Watch: what the creators are posting

    The actual videos behind the report, ranked by views. Three lanes: spectacle raw-view luxury · vibe wordless cozy · taste designer commentary.

    The library — 24 styles

    24 styles across five tiers — ★ Featured leads with the curated top 6, then Trending, Timeless, Historic, Destination (⛲ Outdoor styles work outside — Bali ① and Ibiza ② lead outdoor editing), and Kids last. Each card shows its aka name, a detailed description, palette, and a live TikTok/IG popularity badge (HotNiche, 30-day reach). Click any card for its rooms, description and real example posts.

    Trending aesthetics — and what we're missing

    I scanned 22 trending interior aesthetics on the same scale as the library, ranked by 30-day TikTok/IG reach. Gap = nothing in the library · Partial = a style overlaps · ✓ Now covered = closed by the 6 additions. Updated after the additions: the big colour and dark gaps are now closed — only 3 true gaps remain, sorted to the top below.

    ✓ Bold colour / dopamine — closed

    Was the #1 hole (~4.8M). Now covered by Dopamine Decor (#3, 3.2M), Heritage Maximalism and Burrowcore. Pink/Barbiecore and Unexpected Red fall under Dopamine.

    ✓ Dark / moody — closed

    Dark Academia (the renamed Colour-Drench Heritage) now owns this — Dark Academia (411K) and Moody Interiors (234K) are covered. Only Whimsigoth's witchy/celestial flavour stays open.

    Modern Farmhouse — still open

    616K, the one mid-size gap left. The default US style for a decade; English Country is the UK cousin, not a substitute. Best candidate for a 25th style.

    Remaining true gaps

    Just three, all smaller: Modern Farmhouse (616K), Whimsigoth (294K), Desert/Southwestern (niche). Cottagecore (4M) and Wabi-Sabi (3.3M) stay partials — big, but covered by English Country / Burrowcore / Japandi.

    What's covered

    The library is strong exactly where the credible designer-taste lane is: warm minimalism, color drenching, Japandi, mid-century, modern Mediterranean and the heritage cluster are all direct hits. The two most-named techniques of the moment — warm-but-imperfect minimalism and color drenching — each have a dedicated style. Kids and destination tiers add product breadth the trend cycle doesn't demand but customers do.

    What's not covered

    The library is ~80% warm-neutral, so it misses the loud, colourful counter-current that's actually driving the most engagement: maximalism (the single highest-engagement Reel in the sample), Whimsigoth and Avant-Basic (the named emerging styles), and dopamine decor / bold colourful kitchens. Micro-trends (animal print, checkerboard, cabbagecore, skirted furniture) are motifs rather than styles, likely out of scope — but they're where the comments are.

    Already in the library, but the 30-day research didn't surface it

    Deliberate destination/aspirational bets — they sell on lifestyle, not the trend cycle, so their absence from social trend data is expected, not a problem.

    Why these six were added

    The six additions are now live in the library above (rendered, with images). This is the rationale that drove them: three Trending close the live gaps, three Historic add design-movement depth. Full prompts in proposed-styles.json; the complete spec is in STYLE-LIBRARY-CHANGES.md.

    The strategic read

    The designer-taste lane (warm, collected, anti-AI) and the view-farming luxury lane (marble, ornate ceilings) are diverging hard. The library is built for the first - the right call for an Olivia-Bowen / Zara-Home-type audience. But the gap scan shows the library is ~80% warm-neutral and absent from the two loudest trending lanes.

    Recommendations — done this round ✓

    ✓ Done

    Bold colour / Dopamine — added

    The #1 hole (~4.8M) is closed: Dopamine Decor, Heritage Maximalism and Burrowcore are now live styles.

    ✓ Done

    Dark / moody — named

    Colour-Drench Heritage → Dark Academia now captures the Dark Academia + Moody search demand directly. 70s Revival, Brutalism and Bauhaus also added for depth.

    ✓ Done

    "Found Luxury" → "Quiet Luxury"

    Renamed. By its real name it ranks #6 Strong (419K) instead of dead-last — the demand was always there.

    Next

    Modern Farmhouse (a 25th style)

    The one mid-size gap left (616K). Plus an optional Whimsigoth (294K) for the witchy/celestial niche, and consider splitting Cottagecore / Wabi-Sabi out of their partials.

    Net: the two loudest gaps — bold colour and dark/moody — are now closed, taking the library from 18 to 24 styles. The only true gaps left are Modern Farmhouse (616K), Whimsigoth and Desert/Southwestern, all smaller. Separately, lean renders toward believable and lived-in given the community's vocal anti-AI-render backlash.
