Direct answers to the questions that come up first.

Optimo International is a global design and manufacturing partner for precision-engineered next generation modular building solutions. We help clients deliver buildings faster, with greater cost and programme certainty, using factory-controlled construction methods.

Optimo International is led by Optimo London, headquartered in Mayfair, London, and China XY — a manufacturing partner established in 1992 with over 30 years of experience and exports to more than 50 countries.

Healthcare, education, sports & public assembly, commercial and residential. Our delivery model suits any sector that benefits from speed, repeatability, programme certainty and reduced site disruption.

Up to 50% faster. Up to 90% of the work is completed Solutions in a controlled factory environment in parallel with site works. Foundations, services and modules progress concurrently rather than sequentially.

No. Modular delivery is typically up to 30% more cost effective than equivalent traditional construction once the full programme cost — including financing, preliminaries and risk — is accounted for. Cost predictability is 95%+ because most production happens to a fixed-price factory rate.

Quality is more consistent, not subjectively 'better'. Factory production runs against documented inspection plans at every stage. Defects are caught and corrected before the unit leaves the factory, materially reducing snagging and warranty exposure on site.

Yes. Modular buildings designed and delivered by Optimo are permanent structures with product warranties of up to 30 years. They are also 100% recyclable and relocatable if required.

A 2D structural panel system using cold-formed C-section steel members. Suited to 2–10 storey schemes and hybrid applications including roof-top extensions and infill above existing structures.

A 3D modular system in which fully-fitted building modules are manufactured offsite and craned into place on site. Suited to 4–30 storey schemes — hotel & leisure, student accommodation, healthcare wards, build-to-rent.

Non-loadbearing panels and fully-fitted pods — bathrooms, plant rooms, toilet facilities — manufactured offsite and dropped into a primary structure. The fastest way to remove the most defect-prone, trade-heavy work from the site programme.

Fire compartmentation is engineered into the panel and module build-ups from RIBA Stage 2. Specialist fire engineers are engaged from concept stage and detailing is documented through to handover.

Schemes are engineered to achieve EPC A as a baseline target where regulation applies. Material selections, construction methods and operational systems support BREEAM ratings up to Excellent. Detailing and airtightness discipline enable a path to Passive House where the brief requires.

Up to 40% reduction in embodied carbon and up to 50% improvement in delivery speed compared to equivalent traditional construction. Reductions come from optimised structural specification, reduced material yield loss and lower transport emissions.

An evidence pack covering material certification, in-process inspection, pre-dispatch sign-off, site receipt inspection and post-installation commissioning. As-built BIM model, O&M documentation, warranty schedule and aftercare programme transferred at Stage 6.

Step one is initial alignment — a focused conversation about objectives, scale and programme. From there: initial project optimisation, Net Zero strategy and cost & programme offer finalisation. Most clients reach a fixed-price commercial position within four structured steps.

Yes, where the project information supports it. Fixed-price commitment is one of our core commercial differentiators. The combination of factory-controlled production and DfMA discipline at RIBA Stages 2–3 is what makes fixed pricing reliable rather than aspirational.

Yes. Our manufacturing partner exports to over 50 countries. Logistics, transport route constraints and local compliance requirements are engineered into module size and design from concept stage.
