"The result of that is you create a sterile environment that looks like you've never been anywhere or have nothing to say. When consulting an interior designer ask them which pieces you can take with you into the new design scheme."
Proportion is again important in terms of the relationship between the lounge suite and the dining table. Comparable heights and lines are teamed with a complementary dark colour scheme, while the dining chairs, with their white linen slipcovers, provide a visual counterpoint .
The choice of materials is as important as the colour scheme in establishing the overall tone of the aesthetic, says Foster.
"I don't use synthetic fabrics unless I have to. Natural fabrics will always give you a better level of finish than a synthetic fabric can achieve. Natural fabrics are also easy to maintain for example, the linen slipcovers can be machine washed."
Contrasting materials can be introduced via accessories such as rugs and cushions, but again the desired effect is to remain as subtle as possible, says Foster.
"I generally like cushions to be the same colour as the host piece but in a contrasting fabric, especially in living areas. In bedrooms I like to add a splash of colour and texture, but on the whole I prefer to keep to similar colours."
A permitted exception is the armchair in the lounge with its check fabric, and the striped cushion in the family room.
"That's a deliberate ploy to create a link. The two objects are placed diametrically opposite to maintain a sense of uniformity between the two spaces. Checks and stripes bring a sense of order, in an almost mathematical manner, to a room."
One way Foster prefers to add drama to an interior is through lighting.
