About AGK Holzbau
AGK Holzbau is a business founded in 1997 by Master Carpenter Alexander Georg König, based in Hilden, from which construction projects in Düsseldorf and the surrounding area are managed. The range of services includes the planning and execution of roof trusses of all roof types, dormers, timber frame and half-timbered construction, building within existing structures with additions and extensions, old building and termite remediation, as well as terrace and garden construction. The offer is supplemented by carpentry and art carpentry, drywall, and demolition work. Construction is carried out using structural glulam (KVH) and spruce; for terraces, woods such as Ipe, Teak, Spotted Gum, Larch, Douglas fir, and thermal wood are used. Planning is done using S+S 3D timber construction software, including measurement and preparation for work, and millimeter-precise wood cuts are produced in the company's own facility. For larger projects, AGK collaborates with specialized companies such as Verbundzentrum Wismar and Holzfachzentrum Hüttemann.
