A/S Julius Nielsen & Søn

What A/S Julius Nielsen & Søn does

A/S Julius Nielsen & Søn is a privately held Danish carpentry and construction company founded on 1 December 1874 by Julius Nielsen in Valby, operating continuously for over 150 years as Denmark's oldest carpentry firm. The company provides three integrated service lines: historical building restoration (Restaurering), construction contracting as main or specialist contractor (Entreprise), and a service/maintenance department for ongoing repairs and smaller builds (Serviceafdelingen). Its service offering is underpinned by one of Denmark's most advanced carpentry workshops, producing custom woodwork, historical replacements, and precision joinery, and its methodology emphasises traditional handcraft techniques and same-type original materials to preserve cultural heritage value.

The firm's customer base is concentrated among public-sector and heritage-institution clients across Greater Copenhagen and Zealand, including DSB, Slots- og Kulturstyrelsen, Realdania, Naturstyrelsen, Copenhagen municipalities, and multiple Danish church authorities (sogne/provsti). Go-to-market is enterprise-field-sales driven: the CEO and Bid Manager (Tilbudschef) directly engage professional building owners and participate in competitive public tendering for both one-off projects and recurring framework agreements (rammeaftaler) and service contracts. Revenue is project-based with no disclosed pricing tiers; the firm does not publish pricing and competes primarily on quality, heritage credentials, and a documented reference portfolio rather than price.

The company employs 53 people across administration, tendering, service, enterprise, and workshop operations, with a dedicated internal training coordinator, formal apprenticeship programmes, and partnerships with schools to sustain a pipeline of traditional craft skills. The firm is currently headquartered at Markstykkevej 16, Rødovre (CVR 3541 3480) and is relocating to new shared premises with JJI Akustik & Inventar at Baltorpbakken 12, Ballerup effective 1 July 2026 to expand administrative and workshop capacity.
