What AT4 Grupo does

AT4 Grupo (legal entity OBRAS AT4 S.L) is a privately held construction services firm headquartered at C/ Sorni nº 12 Pta 2, Valencia, Spain (registered in the Mercantile Registry of Valencia on 24 May 2011). The company operates a project-based construction services business across four primary service lines: new high-end residential construction (single-family homes, duplexes, multi-unit buildings), comprehensive interior renovations, commercial space construction with a notable specialization in healthcare facilities (clinics, dental practices, pharmacies), and heritage building rehabilitation of cataloged structures. Technical capabilities include passive housing (vivienda pasiva) construction using bioclimatic design principles and the restoration of singular-protection-status buildings preserving original facades, nolla tile flooring, woodwork, and iron elements.

The company serves three primary segments: affluent residential clients requiring premium finishes and architect-led execution; medical, dental, and healthcare businesses needing specialized clinical interiors; and heritage property owners requiring regulatory-compliant restoration. Its go-to-market is sales-led and direct, acquiring work through referrals, architecture studio partnerships, and inbound inquiries. AT4 Grupo maintains ongoing strategic relationships with multiple renowned Valencia-region architecture studios, including ERRE Arquitectura, Ruben Muedra Estudio, Fran Silvestre Arquitectos, Chiralt Arquitectos, and Hernández Arquitectos, which act as both design partners and referral channels.

Revenue mechanics are one-time project contracts — pricing is quote-based and determined by scope, materials, surface area, and complexity, with no public pricing tier disclosed. The firm employs 11–50 staff (legal form Sociedad Limitada), has no disclosed institutional investors, no subsidiaries, no M&A history, and no funding rounds. It generated one notable award, the 2021 ADCV ORO (Gold) from the Colegio Territorial de Arquitectos de Valencia for the Clínica Alejandr\ía project, and operates with a geographic reach spanning Valencia, Castellón, and Alicante along Spain's Mediterranean coast.
