Working with Lidan

Questions, answered plainly

For public bodies, architects and specifiers weighing up modular timber construction — the questions we're asked most, without the sales pitch.

What kinds of buildings does Lidan deliver?+

Primarily public and commercial buildings: schools and classroom blocks, community centres, park and coastal amenity buildings, offices and hospitality buildings — plus rapid-build housing for local authorities. We take on select private commissions where the fit is right, but our factory is organised around public-sector delivery.

How does procurement work for public bodies?+

We respond to public tenders and direct engagements, and our submissions include the documentation public procurement requires as standard — structural certification, fire strategy, Part L and NZEB compliance, BER assessment, safety file and tax clearance. Our track record includes the Office of Public Works, the Department of Education and county councils across Ireland.

How long does a project actually take?+

The honest answer: it depends on scale — but far less time than traditional build, because the programme runs in parallel. While the site is prepared, the building is already in manufacture. Our 1,000 m² school in Birr was erected to roof level in days; a house extension for Longford County Council took one week on site; our fastest fully factory-finished dwelling went from design to handover in three weeks.

Do modular buildings need planning permission?+

Yes — a modular building is a building, and normal planning rules apply (with the usual exemptions for small structures). The difference is what happens after permission: months of site construction become weeks. We support clients and their design teams through the planning process with drawings, visualisations and specifications.

What standards do the buildings meet?+

A-rated BER and NZEB compliance as standard, meeting the Part L requirements that have applied to public procurement since 2019. Airtightness is measured, not estimated — our results beat the passive house benchmark of 0.6 air changes per hour. On embodied carbon, our assessed buildings range from 249 to 488 kg CO₂e/m², both under the RIAI's 2030 Climate Challenge targets, verified independently and reported in the industry press.

Are modular buildings permanent?+

Entirely. These are engineered timber structures built to the same Building Regulations as any permanent building, with durable façades — western red cedar, charred larch, standing-seam metal — chosen for decades in the Irish climate. They are also, usefully, relocatable: if a site's needs change, the building can move rather than be demolished.

How do the buildings get to site?+

As road-transportable volumetric units, delivered by truck and craned into position — typically to roof level within a day or two. Where ground conditions allow, we install on ground screws rather than concrete foundations: faster, cheaper, lower-carbon, and fully reversible.

Can you report embodied carbon for our project?+

Yes. We support independent embodied carbon assessment (our previous projects were assessed with PHribbon by an external consultant) and can provide figures against the RIAI 2030 targets at design stage. If your specification asks for the number, we can stand over ours.

Can we see a Lidan building before committing?+

Yes — our showroom at Roscommon Business & Technology Park lets you walk through completed buildings and see the factory where they're made. Visits are by appointment: [email protected].
