Anleggsgartnermester Wikholm AS

What Anleggsgartnermester Wikholm AS does

Anleggsgartnermester Wikholm AS is a family-owned Norwegian landscaping and green-infrastructure contractor founded in 1974 and headquartered in Olsvik, Bergen (Vestland county). The firm is in its third generation of Wikholm-family ownership, with Anders Garnes serving as Managing Director since 2019. It employs between 11 and 50 staff and operates as a privately held company with no disclosed external investment. Service lines span ground-level landscaping, natural-stone masonry, hardscape construction, tree relocation and aftercare, and climate-adapted green infrastructure including green roofs, green walls, and stormwater/bioretention solutions. Major documented projects include the BEGIN (Bergen International Green Infrastructure Network) demonstration project, multi-phase landscaping for the Bybanen light-rail extension, and grounds work at Haukeland University Hospital.

The company's technical profile combines traditional craft credentials — Sentral Godkjent contractor status, the Mestermerket master craftsman mark, Approved Training Company registration for landscaping apprentices — with formal management-system certification under ISO 9001:2015 (quality) and ISO 14001:2015 (environmental, awarded 2021). It holds specialist capability in mature-tree transplantation (via the 2017-acquired Sigurd Sondres Trepleie unit) and in natural-stone hardscape, the latter formally recognized by Stein Wikholm's 2025 Natursteinprisen award. Wikholm is a partner in Klimapartnere Vestland, the regional public-private climate network, and was the executing contractor on the BEGIN project, which won the EU Regiostars Awards 2021 Public Choice.

Revenue is generated through project-based tenders and framework agreements with Norwegian public-sector clients (Bergen Kommune, Bybanen Utbygging, Helse Bergen, BIR) and with large prime construction contractors (Veidekke, NCC) operating in the Vestland region. Pricing follows standard Norwegian unit-price and lump-sum construction tendering conventions; long-tail private or retail work is not a material line. Geographic and segment focus is intentionally narrow, with all visible activity concentrated in the Bergen/Vestland catchment.
