I'm even happy if it turns out to be more insulated. It'll have a fairly lightweight flat [yes, I know] roof. -- Roland Perry |

I think you need to talk to Building Control. They are presumably going to want to see standard footings and buttresses (for single skin). Not if it is timber framed which it might as well be - you need 4" of celotex to meet regs and 4" or 6" of timber will provide enough strength for the brickwork. Hard to make a fair job of the brick outside face when its rammed against a fence tho -- it should be clear by now to everyone that activist environmentalism (or environmental activism) is becoming a general ideology about humans, about their freedom, about the relationship between the individual and the state, and about the manipulation of people under the guise of a 'noble' idea. It is not an honest pursuit of 'sustainable development,' a matter of elementary environmental protection, or a search for rational mechanisms designed to achieve a healthy environment. Yet things do occur that make you shake your head and remind yourself that you live neither in Joseph Stalins Communist era, nor in the Orwellian utopia of 1984. Vaclav Klaus |

2019, Andrew remarked: If you mean a half brick, I should recommend a maximum height of about 900mm without buttresses. From a structural point of view, single-brick garages don't seen to fall down very often. But some modest buttresses would be OK as long as they don't prejudice the insulation value. Any vertical loading applied inside would be carried by the studwork, so we are mainly interested in the brick wall not topping over. If it is just a single run of wall then you will need to buttress it. If there is a right-angle joint then triangualtion will provide the necessary strength. It would have right-angles at both ends. If this is going to be habitable, then building control will want to see plans with calculations for structure and thermal performance anyway. I know, but trying to get some rough idea before spending a lot of time on proposals that won't fly (or indeed caving into unimaginative suppliers who want an easy life). -- Roland Perry |

Fair enough - assuming they knew that they were supposed to meet the necessary standard without access to the external face of the wall. As I've said several times now, meeting the required standards was always required. If I had my own way I'd put up some external cladding that looks like pebble-dashing, which about half the houses round here have anyway (plus others with painted brick) and you can't see the surface in question from the road. But one thing my current suppliers agree on is they think the conservation officer will insist on "matching bricks". Maybe I'll have to wait and see what comes through from the planning people. -- Roland Perry |
