011h (011h Sustainable Construction S.L.) is a Barcelona-based construction technology company founded in 2020 that designs and builds low-carbon residential, affordable-housing, flex-living and hospitality buildings using an industrialized building system and a digital platform connecting factory, design and site. The company combines standardized hybrid concrete/wood/steel prefabricated components, an integrated network of qualified manufacturers, and an in-house software platform covering design, contracting and construction execution with end-to-end traceability. It is a certified B Corporation and raised EUR 20M in October 2025 co-led by Ship2B Ventures and CDTI. As of this profile 011h publishes no public developer program, API documentation or machine-readable API contract; its software is an internal/customer-facing product rather than a platform API.
011h is profiled on the APIs.io network. Tagged areas include Construction, Construction Technology, Real Estate, PropTech, and Sustainability.
Regulatory Posture applies to this provider. Its tags matched the
Horizontal (data, software, accessibility, platform) regime, so
Regulatory Posture carries 15 points of the composite.
If this regime is wrong for your business, say so on your
provider repo — the
applicability map is public and we will correct it.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
The six quality facets above are damped to 85 points between them,
because the conditional facet above carries the other
15. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 85% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/011h: open an issue to ask a question, or submit a pull request to add artifacts.
