We build detached homes and high-complexity residential buildings. Structure, envelope and handover under a single technical lead — for owners, investors and architecture studios.
New build asks for a different muscle: ground investigation, foundations, slabs, long spans, cranes, a major-works licence and a programme that cannot be improvised. Nosolo Design delivers high-end residential building with the same rigour architecture studios demand on their hardest projects.
One technical counterpart. An itemised contract. Milestone certifications. A digital dashboard for owner, investor and design team. That is how risk is controlled — not with promises, with method.
Casagemas — New-build house, Badalona
The plot decides. We study access, neighbours, levels and ground before we commit to a date. Pads, raft, retaining walls or micropiles according to the geotechnical report.
In-situ and fair-faced concrete, steel for long spans or extra storeys, glulam or CLT. Slabs, walls, stairs and spans the project asks for — not the ones that are convenient to build.
Envelope, roof, airtightness and building code. Heat pumps, ventilation, electrical and plumbing resolved under the same command as the structure — not bolted on at the end.
Coordination with the technical project, planning and, where required, independent technical control. The site programme starts with a real calendar, not a marketing date.
We speak the studio's language. Millimetric respect for the author's design, buildability solutions and a shared portal. Contractor for architects →
Measurable items, certification milestones and written scope changes. The client sees cost and progress without daily visits. Site tracking →

Badalona · New build
A structurally demanding new-build terraced house, built as a vertical extension: fair-faced concrete, a crafted stair and a steel-frame extension. A dense urban plot, with access and neighbours that do not forgive improvisation.
Chiva · Valencia
A new detached house on a slope. Clean volumes, a continuous envelope and a complete build — from the plot platform to the keys.
Built for the person who signs the cheque and the person who signs the drawings. The same method serves a private owner, an investor and a studio.
