Thickness of ceiling joists in loft
My ex-council house semi is basic in design, but built like the
proverbial brick "outhouse". Since all the internal walls, ground floor and first floor, are of solid masonry, the joists in the loft seem really strong with no discernible spring when one steps along one. The joists are now partially boarded over, but I was wondering what a brand new house is like in the loft. In a modern house, the walls are usually stud type, i.e. not load-bearing. So how strong are the ceiling joists in the loft in a modern house? How to they stay up without load-bearing walls to support them? MM |

They are ruff trusses. Each truss is all one piece and spans the width of the house. The internal walls usually have a wood piece here and there from floor to roof trusses giving extra mid way support on some. Some modern house are very well made and very sturdy. The problem with older houses is they lack insulation and cost a fortune to run. |

You want to take what this IMM tit says with a pinch of salt. I don't
wish to do a Felix Tilley on him, as any input -even negative input, has some value if only to identify the arseholes of the planet. Cheap two storey housing is based on a brick outer shell with an inner leaf of breezeblock. This is far less substantial than timber-frame. The upper storey is made of studwork that reaches just short of the trusses. The trusses are usually made of 4 x 2 the pieces joined together by dogs made of steel plates. There are no purlins and there are no walkways. The whole is stitched together with 4 x 1's and the roof tile battons. It is engineered to be strong enough when closed to take the weight of an heavy aerial fitter plus his tool-box and a cladding of snow in an howling gale. (Yes right!) Of course you can crawl inside it. How do you think they run the electrics? -- Posted via Mailgate.ORG Server - http://www.Mailgate.ORG |

Give me an ex-local authority house anytime. They are BUILT, not like todays
rubbish. Yes ok, they may not be upto today's modern insulation standards but in 5 years time, the modern houses will probably not meet the standards of the day either.

They form the bottom part of a braced "A" frame structure that is the roof. There's a single stud wall in the middle which I no doubt provides a little bit of support. The beams can support my weight but there's no way I could make the space into a liveable space like that. I'm sure over time the ceiling would sag. Tncidentally the builders put down a length of chipboard flooring, to to the electrics or lay the insulation or something but they couldn't be bothered to lift the board up (which isn't nailed or anything) to put insulation under it! That's how I know the ceiling can suport my weight 'cos I've been adding extra insulation recently. |

In a modern house, the walls are usually stud type, i.e. not
load-bearing. So how strong are the ceiling joists in the loft in a modern house? Frequently, even in modern houses, there is a masonry wall in the middle that rises to loft level (there was in my last house). Also, don't assume that stud walls are non structural. Many houses are built entirely from structural stud walls without any masonry in sight (except maybe a decorative brick shell). Christian. |

The problems with most modern houses are that the ceilings are too low and
the rooms too narrow. No dount all thanks to ergonomics - the science of making things just too small to be comfortable. Today's obsession with environment (only the outdoor environment, mind, which is not where most people spend their time) means a lack of fresh air and higher levels of pollutants indoors. When I lived in a new flat, I felt like I was always getting a cold (that bunged up feeling). As soon as I moved to a draughty old victorian house with single glazing and open fires, I felt much healthier. Stuff the heating costs, health is more important than some eco nonsense.

So how strong are the ceiling joists in the loft in a modern house? How to they stay up without load-bearing walls to support them? The roof is usually constructed of trussed rafters - see http://www.trussed-rafters.co.uk/ttypes.htm for typical shapes - which bear on the external walls only: any support given by internal partitions is purely incidental. They are perfectly strong enough for the design loads but no stronger than required - computer design minimises the sizes of the timber members and connecting plates. Generally you would expect the ceiling ties to be capable of taking a distributed load of about 0.75kN/m2 or 15lb/ft2 -- Tony Bryer SDA UK 'Software to build on' http://www.sda.co.uk Free SEDBUK boiler database browser http://www.sda.co.uk/qsedbuk.htm |

Why shouldn't room size be included as a measure of quality? It's not the choice of most people to live in a pokey rabbit hutch. Not everyone has the luxury of enough money to have a true choice. The price of the smallest hosues will always tend to creep up to whatever the maximum the average first time buyer can afford. If the smallest houses were a bit bigger, they wouldn't necessarily be more expensive to buy, but it would mean an improvement in the quality of the country's housing stock, and in the living conditions of its population. In fact, rather than build ever smaller starter homes, perhaps the planning authorities should encourage the building of lots of large houses instead. That would take the pressure of housing prices by reducing the demand from people with loads of cash. Eventually this would come through to more sustainable prices at the lower end. Mal |

At least the minimum sizes. A 3 bed house should have minimum room sized as they generally have 5 people in them. You need a toiler downstairs, so they can give minimum room sizes, and also minimum sized plots and proximity etc. if people want to pay big money for a Barratt house or Victorian cottage with tiny rooms that is their choice. In certain price brackets you have no choice, they are all poky.

But don't forget that HMG get extra taxes by having more houses, in the form of council tax which is applied to each property, so it's not in HMG's interest to expand the footprint size of new houses - in fact the reverse is true. If you have two houses occupying AxB footprint then I believe the council tax for those two properties will give government rather more than having a single dwelling occupying 2xAxB. Not forgetting that the latter house might well be in the topmost band so no matter what size it was increased to it would still pay the same council tax.

So how strong are the ceiling joists in the loft in a modern house? How to they stay up without load-bearing walls to support them? The roof is usually constructed of trussed rafters - see http://www.trussed-rafters.co.uk/ttypes.htm for typical shapes - which bear on the external walls only: any support given by internal partitions is purely incidental. They are perfectly strong enough for the design loads but no stronger than required - computer design minimises the sizes of the timber members and connecting plates. Generally you would expect the ceiling ties to be capable of taking a distributed load of about 0.75kN/m2 or 15lb/ft2 Basically, the lofts in these modern houses don't sound to me anything like as sturdy as in my ex-council house! Maybe I should buy TWO ex-LA semis where I want to move to (Lincs) and make a single home out of them. Or live in one half and rent out the other half. By the way, does the quality of council house building vary across the country? Where were the best ones built? MM |

This house is as dry as a bone and is solid enough to last another fifty years at least - with minimal maintenace. I know, because I have just spent a week working in the loft and am continually amazed at the huge timbers they used. Can you say that about a lot of the jerry building that has gone on in Britain over the past two decades? MM |

If you want one like that find who makes them. |

By the way, does the quality of council house building vary across the country? Where were the best ones built? Of course. I've seen ones built from a steel frame with plasterboard walls and PVC exterior cladding. Ugly. Regards, NT |

This is where Britain continually goes wrong with our short-termist attitude to most endeavours. Poorly designed houses that cost a fortune to heat and collectively contribute vast amounts of CO2 to global warming should be demolished. The current new houses should get 100 years. But if far superior newer, no heating houses are common in 30, 40, 50 years, it is easy to dispose of the current crop. Making poor technology to last is silly. |
