Coltart Earley Architecture

What Coltart Earley Architecture does

Coltart Earley Architecture is a Glasgow-based architectural practice founded in 1990, operating as a subsidiary of Holmes Miller Ltd., a larger Scottish architecture group. The firm delivers an integrated suite of professional services spanning residential architecture, RIAS-accredited conservation and renovation, accredited Passivhaus and energy design (including SAP calculations, EPC assessments, embodied carbon modelling, and Retrofit solutions), urban design, and community-focused architecture. Its technical differentiator is the combination of thirty years of historic-building conservation experience with low-carbon design capabilities, supporting a stated mission aligned to Net Zero Carbon and ending Fuel Poverty.

The practice serves three primary client verticals: Community Led and Community Owned organisations, Housing Associations and Local Authorities, and Private Developers together with Individual clients. All work is delivered regionally across Scotland, with the headquarters at 89 Minerva Street, Glasgow. The firm holds ISO 9001, ISO 14001, RIAS practice accreditation, Investors in People status, and is a Living Wage employer, credentials that underpin eligibility for public sector and conservation tendering.

The business model is project-based professional services revenue, with no standardised public pricing. Go-to-market combines community-led positioning (Community Engagement, Choice, and Consultation) with direct engagement of public and private sector clients, where repeat commissions from satisfied clients function as the primary demand generation mechanism. The firm is privately held under Holmes Miller Ltd. and has no disclosed funding, headcount, or revenue data.
