The ''[[Regelbau]]'' (standard build) system used books of plans for each of over 600 approved types of bunker and [[casemate]], each having a specific purpose, having been updated as enemy constructions were overrun and examined, even testing some to destruction for effectiveness. They incorporated standard features, such as an entrance door at right angles, armoured air intake, {{convert|30|mm|adj=on}} steel doors, ventilation and telephones,<ref name="EG">{{cite book |first=Ernie |last=Gavey |title=German Fortifications of Guernsey |year=2001 |publisher=Guernsey Armouries |isbn=978-0953163106}}</ref>{{rp|7}} internal walls lined with wood, and an emergency exit system.<ref name="Regelbau">{{cite web  |url= http://www.regelbau.com/on_regelbau_gb.htm  |title= The Regelbau concept  |access-date= 10 August 2016  |archive-url= https://web.archive.org/web/20161118062830/http://www.regelbau.com/on_regelbau_gb.htm  |archive-date= 18 November 2016  |url-status= dead  }}</ref> There were over 200 standardised armour parts.<ref name="JEK">{{cite book |first=J.E. |last=Kaufmann |display-authors=etal |title=Fortress Third Reich: German Fortifications and Defense Systems in World War II |publisher=Da Capo Press, 2007 |isbn=9780306816352}}</ref>{{rp|350}}

The standardisation greatly simplified the manufacture of equipment, the supply of materials and the budgetary and financial control of the construction as well as the speed of planning for construction projects.<ref name=HOT1/>{{rp|50}}

To offset shortages, captured equipment from the French and other occupied countries armies were incorporated in the defences, casemates designed for non-German artillery, anti tank and machine guns and the use of turrets from obsolete tanks in ''tobrukstand'' pill boxes ([[Defensive fighting position#Tobruk|tobruk pits]]).<ref name=HOT1/>{{rp|51}}
