Creating shops within a shop.

The key thing for all stores is to create a strong definition between all the different departments with in the store.
The use of signage and branding is a key to creating the right effect, using the stores architecture such as columns, natural wall breaks ect, with the right fixtures with enhance the clarity of these sub-shops.
Where possible try to use different fixtures in each section as this will help create a strong definition of each shop.
In a home store, use pigeon holes and room dividers to divide up sections. For example, furniture, lighting, bedding, bathroom. This will all so help to create room sets.
