I'm not sure what part of the image is to be paved, but you have several options.
The simplest would be to leave a border of at least 600mm width at the fences and drain towards those, You could also send some of the potential surface water onto the lawn, if necessary.
It's not wrong, per se, to drain towards a house or other building: it's less than ideal and best avoided, if possible, but as long as any paving against the house is 150mm below DPC, or you have some form of interception, such as a linear drain or a dished channel, then it's not an actual breach of Building Regs.
