Scale indicators3 records

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• Pasquill (Saint-Gobain): UK's largest manufacturer of roof trusses and engineered timber solutions, owned by Saint-Gobain. Operates at national scale across a wider product portfolio but competes directly for housebuilder roof truss and joist supply where Harmony bids.

Direct peers

• B&K Structures: UK timber engineering specialist manufacturing glulam beams, CLT, and steel-timber hybrid solutions. Overlaps with Harmony's glulam and engineered wood product range, particularly on commercial and Passivhaus-style premium projects.
• Crendon Timber Engineering: UK timber engineering manufacturer producing trussed rafters, posi-joists, and engineered timber solutions for commercial and residential construction. Direct product and customer overlap with Harmony's truss/joist and timber frame business.
• Frame Homes: UK manufacturer of closed and open panel timber frame systems, roof trusses, and engineered joists for self-build, residential, and commercial projects. Comparable bespoke manufacturing and project-based delivery model to Harmony.
• Pinewood Structures: UK timber engineering and timber frame manufacturer producing roof trusses, floor joists, and structural timber solutions for residential and commercial construction; direct overlap with Harmony's trusses, joists, and timber frame core range.
• Kingspan Timber Solutions: Kingspan's UK timber frame and engineered wood division (formed from the acquisition of Stewart Milne Timber Systems) designs and manufactures timber frame structures, roof trusses, and floor cassettes for residential and commercial projects — directly comparable product overlap with Harmony's frame, truss, joist, and cassette offering.
• Donaldson Timber Engineering: UK manufacturer of trussed rafters, engineered metal web joists (Easi-Joist), and timber frame solutions serving housebuilders and developers. Highly comparable to Harmony on product mix and B2B project-based GTM model.
• Taylor Lane Timber Frame: Welsh-based bespoke timber frame manufacturer supplying self-builders, developers, and commercial clients across the UK with wall panels, trusses, and Posi-Joist systems — strongly comparable in product range, customer segment mix, and bespoke project delivery.

Regional players

• McCarthy Timber Engineering: Regional UK timber engineering contractor operating primarily in the South/West of England on trussed rafters and engineered joists. Comparable product set but different geographic footprint from Harmony's Kent/Southeast focus.

Emerging players

• Eurban: Specialist UK supplier/manufacturer of mass timber and engineered wood products (CLT, glulam) for low-carbon building projects. Adjacent — competes for the same Passivhaus/low-carbon commercial project pipeline where Harmony's glulam and timber frame also bid.
