Amazon has applied to Cannock Chase Council to extend its Staffordshire fulfilment centre, which will see the interior reconfigured to double capacity.
The application seeks to create a new entrance to the building and construct a new roundabout within the site to enhance traffic flow in and out of the centre.
The online retailing giant also proposes to add more car parking spaces and a new bus stop on the site.
If the application is successful, Amazon says the expansion would create 350 permanent jobs at the site in Towers Business Park, Rugeley.
The expansion will also double the capacity of the existing warehouse.
Leader of Cannock Chase Council, councillor George Adamson said: "A planning application has been received which, if approved, will see the expansion of Amazon's distribution capacity at their warehouse in Rugeley.
"Amazon's proposal to invest further in Rugeley is to be warmly welcomed, together with the new jobs that would be created. This shows that Cannock Chase is an attractive place to invest and create jobs for local people."
The warehouse opened in 2011 and currently employs over 600 people.
It is not Amazon's only UK fulfilment centre. It also has operations in Doncaster, Dunfermline, Gourock, Hemel Hempstead, Milton Keynes, Peterborough and Swansea Bay.
Amazon is slowly taking its share of the DIY and home improvement market in the UK, and to prove this the retailer recently reported that in the lead up to May Bank holiday it had seen huge increases in sales of DIY products
For example sales of sledgehammers rose 73% compared to last year and welding equipment was up 74%.
