Hotel Bellevue Vienna — Lobby & Bar Renovation

The only product with explicitly confirmed use class for hospitality/high-traffic (≥33 equivalent), the highest slip rating (R10/C vs R10/B for the others), and a colour that genuinely matches the brief's 'warm mid-grey / greige' spec. At €63.16/sqm on current promotion (list €90.23 = within stated budget), it delivers premium hotel credentials at mid-range cost. Strong EPD documentation supports DGNB Gold ENV1.1 LCA submission. For a 4–5-star lobby renovation, the use class confirmation eliminates a critical risk the other two options carry. Order a written spec confirmation of Nutzungsklasse 33 from the Porcelanosa AT/DE representative before issuing to contractor.
Action required: Request written Nutzungsklasse 33 confirmation from Porcelanosa AT/DE rep before spec issue

Best material match for the brief: the 'kerngeräuchert' (smoke-treated) finish directly fulfils the 'smoked or lightly brushed' finish specification, with a medium-warm brown tone and no orange. GREENGUARD Gold is the strictest chemical emission certification available — critical for a hotel bar where guests are proximate to the floor surface. ProActive+ (antibacterial, allergen-free, maintenance-free) is specifically suited to hospitality environments. Austrian manufacturer supports DGNB regional sourcing credits. Thickness at 12.2mm is slightly below the 14mm spec — acceptable given wear layer and use context; obtain written deviation agreement from interior consultant. Confirm availability and lead time with Megaparkett.at Vienna before issuing spec. If lead time is unacceptable, fall back to Parador Bardolino (mid tier) which has DGNB Navigator listing and Blauer Engel.
Action required: Confirm lead time with Megaparkett.at Vienna before spec issue; request written thickness deviation acceptance; get PEFC/FSC chain of custody certificate for DGNB documentation

Neolith Basalt Black delivers the strongest sustainability credentials of all three at the lowest estimated total cost. Carbon neutral since 2019, Cradle to Cradle Bronze, and EcoVadis Gold are exceptional distinctions that directly support DGNB Gold documentation. The satin finish suits a bar counter (less fingerprint-prone than ultra-matt). Deep black-grey with basalt character is an excellent aesthetic fit. The main consideration is total lead time of 5–7 weeks — order immediately upon project award. Eased or mitre edge available via any local Steinmetz. For the cleanest black (uniform graphite) with Austrian supplier, Dekton Domoos (mid tier) is a strong alternative with an established local partner at Gröbner Stein.
Action required: Order early — 5–7 week lead time. Contact MAAS GmbH Germany (ships to AT) or identify a local Vienna Steinmetz who can source Neolith

The brief explicitly calls for 'handmade ceramic or terracotta, zellige-style' with 'natural glaze variation' — ZAGORA is the only product that genuinely satisfies this specification. Authentic Moroccan zellige has inherent tonal variation, irregular glaze pooling, and surface undulation that industrial ceramic cannot replicate. At €119/sqm × 20 sqm effective area = €2,380 total supply cost, this is a very modest budget impact for a 4.2m floor-to-ceiling feature wall. The forest green / emerald tone is visually striking against the dark bar counter. Order a sample tile (€0.30 + shipping) for client sign-off before ordering. If the hand-made variation is unacceptable to the client, substitute with Marazzi Zellige Bosco (mid tier) which offers the most consistent industrial zellige-look from a credentialled European manufacturer.
Action required: Order sample tiles before committing to colour (Smaragdgrün ZE-1025 and optionally Perlgrün ZE-1006 for lighter variant); confirm 20 sqm order quantity with ZAGORA for shipping cost

The brief specifies 'brass or antique brass' and 'individual pendants at varying heights' — the LE17609's genuine brass body in bronze-antique-matt finish and height-adjustable pulley mechanism directly fulfils both requirements. 100% handmade in Italy, immediate dispatch (no lead time risk), and well within budget at €233.95/unit. The frosted glass shade diffuses light warmly, appropriate for bar atmosphere. At 290mm diameter the shade is 10mm over spec — negligible visually. Ceiling canopy included. For 12 units: €2,807.40 total, €572.60 under the max budget. The SLV (budget tier) is a valid cost-save at €2,527 but the copper-coloured glass shade is not a genuine brass product — may feel 'off-brand' in a 4-star hotel bar.
Action required: Confirm Austria delivery service with Licht-Erlebnisse before order; also check LE89336 availability in case finish preference leans towards lighter brass tone

This is the strongest architectural specification for Hotel Bellevue Vienna's lobby. The WAD 36 is a numbered, sequentially produced Art Déco fixture based on 1920s originals — precisely the 'Art Deco or Gründerzeit-influenced' character required. Polished brass body and opal glass diffuser meet material spec exactly. In stock with immediate delivery (no availability risk). At €513/unit it is below the €600/unit budget ceiling. For 8 units = €4,104 total. The mid-range Casa Lumi CL2942 is a credible alternative if the Art Déco cylinder form suits the lobby geometry better — but the nickel finish must be changed to brass on order. If budget is a constraint, the mid-range option at €354/unit (€2,832 total) saves €1,272.
Action required: None for Tecnolumen. If Casa Lumi is selected: explicitly order brass finish variant — standard ships in nickel

The hansgrohe Metropol is the only option that exactly meets the WELL Building Standard water efficiency requirement (5.0 l/min) — a stated preference in the brief. IBU-verified EPD (EN 15804+A2) provides the strongest DGNB documentation of the three. Brushed Bronze finish is warm and sophisticated, well-suited to Hotel Bellevue Vienna's character. Push-open waste set included (saves €30–50/unit vs GROHE). iF Design Award 2023 confirms aesthetic quality. The 10–28 working day lead time means it must be ordered immediately at project award. At €354.17/unit × 4 = €1,417, it's only €94 more than the GROHE Essence XL total but delivers full WELL W05 compliance and a more refined aesthetic. For a DGNB Gold project, having an EPD from IBU for sanitaryware is a meaningful documentation advantage.
Action required: Order immediately — 10–28 working day lead time. Verify AT delivery via Obadis or Skybad. Cross-check availability at sanitaer-vor9.at or Sanitino.at as fallback suppliers

The square rosette design is the most minimal and architectural option — directly matching the brief's 'minimal, no ornate casting' requirement. Solid brass construction is appropriate for a hotel interior where door hardware endures 100+ daily cycles. Häfele Group ISO 14001 provides basic sustainability documentation. At €146.22/set × 22 = €3,217, this is within the €200/set ceiling. The critical action is to confirm with Häfele Austria whether a brushed/satin brass finish variant (PVD or lacquered) is available for this model — polished brass (glossy) is the only currently confirmed finish, which deviates from the brief. If satin solid brass is unavailable in LDH 3350, either accept polished brass (discuss with interior consultant) or fall back to Griffwerk MARISA GK4 for satin finish in brass-look (zinc alloy, cheaper, GK4 rated).
Action required: Confirm satin/brushed brass finish availability for LDH 3350 with Häfele Austria before spec issue; also confirm mix of BB / PZ / WC configurations needed across the 22 internal doors
