The first step is to de-clutter, whilst minimalism is about more than simply de-cluttering, this is still an important phase because once you have de-cluttered your home you will have a better idea of how much new storage space will be required to house all your essential items.
Then you will need to create the additional enclosed storage - for a truly minimal look this should be as unobtrusive as possible - simple cupboards painted the same color as the walls (neutral, of course) so they blend in - and should make use of existing alcoves and niches to avoid encroaching on a room's floor space. An essential part of minimalist living is keeping the floor clear of any unnecessary items.
Always overestimate how much storage you think you will need - one of the biggest factors in the failure of a minimalist home is not having the storage space to easily keep those belongings out of sight.
Next, consider whether you need all of the furniture that your rooms contain. There are certain essential furniture items that every room needs: chairs, tables, sofas, beds, etc but there are also many that you can live without. But a minimalist home should still be comfortable so ensure there is enough seating for the family and guests. There's little point your guests admiring your sleek, minimal home if it is nowhere comfortable for them to sit down.
