white washed brick looks great with a tin roof and very country - think tuscany. Reclad with brick. Other wise just change the supporting poles from green to timber to match the verandah and stick with what you have. It's probably worth saving your money until you can afford to repaint the roof too and make it all work together. Work with perspectives too. Right now the focus appears to be on the roof because there is nothing drawing your eye away from it. Maybe planting coloured flowers in the front garden or great outdoor furniture like the cane lounge but with different colour cushions etc.

Cream always looks good with green, maintain the same green for windows & door. Having said that you can choose any colour by repainting the gutters & fascia etc. Get lots of colour swatches & hold them up to the roof (from a distance) to see what looks best to you. Then get some sample pots & paint so you get the proper effect of the end result. Look around at other painted homes & magazines etc, to get an idea of what you really like.

Both colours would look good with the flooring you plan Is the brick wall staying? The darker shade would balance the strength of the brick colour The white kitchen will make the whole room blend together as it will 'clean' the colours consider how you intend to decorate the area - is the green going to feature heavily elsewhere? (like living spaces?)

Thanks Jane. the render walls are natural yellowy colour. im trying to match with maybe stowe white or antquite white dulux paint stowe is a little dark.
