Loft plans

[^woody^]

Never mind the copyright then, just use someone else's plans to save yourself some money, and hope they don't notice.

And hope that planners or building control don't want some changes, and that when the builders come to build they don't charge you extra (more than the amount saved) because the plans are shi'ite and don't actually match what is there.

One of the loft conversion specialists where I used to work would use the same set of calcs for every job in the same street, unfortunately the original terrace wasn't all built at the same time and there was a single king post truss rather than two king post trusses as on the other parts of the terrace he'd previously worked on. Hadn't even bothered to look in the loft prior to starting on site!

Thanks to all for the input here – I take it all onboard.


I guess what I really need to ascertain firstly is if I need planning permission. Looking at the plans I have there are these measurements:


HIP TO GABLE: L2.52 X W8.86 X H2.17 / 6 = 8.07m3


PROPOSED DORMER: H2.03 X W5.75 X D4.20 / 2 = 24.51m3


TOTAL = 32.58m3


The measurement from the ridge to the back of the new roof would be 4208 and the height at the back 2033. I can’t see a measurement showing the width of the property (don't think this is shown in the measurements above?? )



Here is the guidance:

https://www.planningportal.co.uk/info/200130/common_projects/36/loft_conversion

and as mentioned I think we would be within all of those limits / conditions but I am not sure of the first one:

• A volume allowance of 40 cubic metres additional roof space for terraced houses*

And then..



If I don’t need to submit plans for planning permission then will I need to submit for building control / regs?



Is it stupid to try and do work around plans that although drawn up for a property that appears the same and was built at the same time, haven’t been checked on our property and if it is unethical plus violating copyright to do so?



More thoughts, advice and opinion if you will!



Many thanks,



Will

If you have means to amend the plans if needed, use them.
Trouble would be if you need to change something and you can't.
Copyright?
Who is gonna know?
Those plans look all the same, in fact, first thing a local architect will do is to check if there ore plans submitted to adjacent properties and work from there.

Why would the OP want to breach copyright and risk using plans that aren't accurate in some material respects?

HIP TO GABLE: L2.52 X W8.86 X H2.17 / 6 = 8.07m3

Isn't it 1/3 base area X height for a pyramid?

Not sure if I am answering the question but we are end of terrace so will be extending to the side and the back..

Thanks,

Planning permission and building control are quite different. You may or may not need planning permission, you will need building control to sign it off.

The level and type of paperwork you need for them is different, one of the more experienced people around here can correct me but you'd almost certainly want/need a structural engineer to check the numbers (and Building Control would definitely want their sums) and I imagine the engineer will want architectural plans, as would the builders.

Why don't you find an architectural technician and ask them to design one like next doors, PS here's the publicly available drawings they produced.
