Balcony furniture fails on depth, not on area. A balcony can be generously long and still not seat two people, because seating requires a clear run from the railing to the wall of around 180cm once a table, two chairs and the space to push them back are counted. Length adds views. Depth adds usability.<\/p>\n
No published dataset records the dimensions of UK balconies as built, and we have not measured a sample, so this report presents no survey of 30 balconies. What it does present is fit geometry: the depth and width a bistro arrangement actually needs, tested against the minimum private outdoor space the London Plan requires, which is 5 square metres for one and two person dwellings with a minimum depth and width of 1.5m. Against that benchmark, a two seat bistro set fits a compliant new build balcony, but only with the right table shape and the right chair.<\/p>\n
Balconies are designed individually as part of each building, and their dimensions are recorded in planning drawings rather than in any central register. There is no national dataset of as built balcony sizes, and no trade body collects one. Anyone presenting a table of thirty typical balcony sizes is presenting a selection, not a sample.<\/p>\n
What is published is the standard that new development is designed against. The London Plan private outdoor space standard is the clearest, requiring a minimum of 5 square metres for one and two person dwellings, increasing with occupancy, and setting a minimum depth and width of 1.5m so that the space is usable rather than merely present. That minimum depth figure is the number worth carrying into any furniture decision, because it tells you what the smallest compliant balcony gives you.<\/p>\n
Older stock is a different matter. Juliet balconies provide no usable depth at all, and balconies on mid century blocks are frequently shallower than current standards require. In those cases, measuring your own is the only reliable approach, and it takes two minutes.<\/p>\n
Three dimensions decide whether a bistro set works. The first is the depth of the seated zone. A dining chair is around 45cm deep, and pushing back to stand requires a further 30cm behind it. Two chairs facing each other across a 60cm table therefore need roughly 45 plus 30, twice over, plus the table: about 210cm for comfort and about 180cm at the tightest workable setting.<\/p>\n
The second is the width of the through route. A balcony is usually accessed by a door at one end, and if the furniture blocks the route, the space stops being used. Leave 60cm of clear passage past the furniture where the balcony is long enough to allow it.<\/p>\n
The third is the height relationship with the railing. A standard bistro table at around 70cm to 75cm sits below the top of a balustrade, which is typically 1.1m, so a seated person looks at the railing rather than over it. On a balcony with a solid parapet rather than glass or bars, a higher table and bar stools can restore the view entirely, and this is the single most effective change on a balcony with a solid front.<\/p>\n
The arrangement that resolves the depth problem is straightforward: put both chairs on the same side of the table, facing outwards, with the table against the railing. Two people sitting side by side need around 120cm of depth rather than 180cm, and on a narrow balcony that is the difference between using the space and looking at it. It is also why we suggest starting with the table when choosing from a range of bistro tables UK<\/a>, since the table shape determines whether the side by side arrangement is possible.<\/p>\n The table below sets out what a given clear balcony depth will accommodate, based on standard furniture dimensions and the clearances needed to sit down and stand up. Depth is measured from the inside face of the railing to the building wall.<\/p>\nWhat fits at each balcony depth<\/h3>\n
