The UN's cultural and scientific organisation's heritage committee approved the decisions during a meeting in Busan, South Korea, on Sunday where a total of 30 new nominations were under consideration.
The housing development in the southwest of the German capital is not a new entry, but an addition to the Berlin Modernism Housing Estates site, joining six other complexes that were first recognised by UNESCO in 2008.
The new World Heritage Site in Normandy covers the beaches where Allied forces landed in on D-Day on June 6, 1944, to begin the liberation of Western Europe from Nazi Germany.
The site includes the five historic landing beaches - Utah, Omaha, Gold, Juno, and Sword - as well as other memorials associated with the Allied invasion.
The Allied forces consisted primarily of US, British, Canadian, Polish, and French troops.
Around 3100 landing craft carrying more than 150,000 soldiers crossed the Channel to northern France. Thousands were killed in the fighting that followed.
With the addition of the D-Day landing beaches, France now has 55 UNESCO World Heritage Sites, the same number as Germany.
Only China (60) and Italy (60) have more UNESCO World Heritage Sites.
The Berlin Modernism Housing Estates site recognises social housing complexes built mainly during the Weimar Republic.
It includes the famous Horseshoe Estate in the Britz neighbourhood and the White City in northern Reinickendorf.
The Zehlendorf Forest Estate was built between 1926 and 1932 under the lead planning of architect Bruno Taut, in collaboration with Hugo Haring and Otto Rudolf Salvisberg.
During their construction, the Bauhaus-style buildings provoked fierce opposition within conservative circles.
Today, however, the concept is undisputedly regarded as pioneering: under the guiding principle of 'light, air and sun', the estate was ahead of its time in prioritising residents' health and wellbeing.
Taut's vision combines modern, open architecture with a setting characterised by green spaces and trees. The aim was also to create affordable housing for a broad cross-section of society.
A distinctive feature of the estate is that, in terms of area, it is the largest of all the Berlin Modernist housing estates.
Added to this are the colourful walls - yellow, blue, green or burgundy-red facades, three-coloured window frames, and brightly coloured front doors - which have also earned the complex the nickname 'Parrot Estate'.
However, of the 4000 people who now call the Zehlendorf Forest Estate home, only some are pleased with the UNESCO decision.
Some residents are concerned that recognition as a UNESCO World Heritage Site could lead to rent increases and that the already stringent heritage protection regulations might be tightened even further.
