You should have minimum 5 ft but 6 ft is ideal. I've played pool where tables are 4 ft from the wall and it is too close. The standard pool cue length is 57" and the draw length is about 6" so 5 to 6 ft would be ideal.

For chair scoot and sit space, I'd follow the guidelines for a rug - 4' all around. Then you want to be able to navigate around the table while people are seated, so add another 18" all around. Are you locating the table at the end of the galley? Maybe you could use a banquette on one side or in the corner https://www.houzz.com/photos/3rd-street-bungalow-traditional-kitchen-austin-phvw-vp~214425

I haqve just seen this , and it is well over a year old , so presumably you are well into renovations , or maybe finished . Here's my take though -- probably too late though ! Your picture looks like those 70's photo's that faded and yellowed ( sorry to be rude ) . So freshen and modernise . Paint the walls white -- not beige or yellow . It will look so much 'cleaner' . redo the dark uprights and base boards -- I can't tell if they are dark green , or black , but I'd do black stain over it . The fence I would also do in black . The yard , step one , would be hide and soften it . The Cape Cod chair paint in white , with the pailings in bright primary colours -- each one different . Add 2 or 3 planters -- different shapes and sizes and heights , but all stained a nice Kwila brown or charcoal or similar . Big leafy plants , cactuses , yukkas , maybe white and light brown pebbles , marigolds , colour , texture , different height plants . Personally , I would go further -- paint the roof , rip up most of the pavers , possibly even change the windows to bronze or charcoal frames . Just some quick ideas from an experienced amateur haha .

I assume you have sailed into your renovations Susan ? The pictures actually look like 2 different houses -- different colours , different styles . I quite like the 'red' ( 2 storey ) side of the house -- even the conservatory and that pattern on the deck railing -- personally I'd paint it in a charcoal , but it's liveable . NOT a fan of the yellow opaque glass , and I'd paint around the outside of your 2 garage doors approx 80-100mm wide white borders to match the rest of the joinery . The other side though -- the roof ( as you said ) would be my first thing -- I'd go a browny/red , very similar to the panels on the other side of the house . The gutters and window sills I'd go a superbright blood red , and even though I agree about the cream veneer bricks and steps -- I'd leave the veneer , and either paint , or preferably tile , the steps in charcoal , and add a couple of 'chunky' stainless rails on the sides . And the base board -- I'd do it in charcoal too . It would not only look better , but make the house look longer and sleeker .
