There is no point what so ever in discussing your roof until who ever did the drawing designs a sky hook to support the top 89x152 USB and the double bolted timber bressummers supporting the roof light. When you have a properly designed practical drawing then suggest you come back Regards oldun

Sorry posted twice. :oops: :oops:

Depth of extension 3700, assume cavity wall is 300, so less external skin, cavity and 50 mm ledger plate = 250 = 3450, for half run. Your true rise is 500 above existing roof to under side of first floor window sill less minimum of 150 for flashing = true rise of 350 therefore your true...

Read our post to catlad. Regards trimmers, nine times out of ten you can still keep your joist centres round stair wells. On the tenth you slip in either one or two extra joists. One other point. If you are the coddy, it is for you to tell trades what you want and not for trades to tell you...

Comments like the above, only serve to highlight your lack of knowledge.. The specification that we posted is recognized practice, and is approved by both NHBC and LABC. The added advantages are that internal block work murder lift and bedroom lift can be built of off the new floor. The...

Okay no problems. Post will be a bit long and detailed. You may have to read it few times for it all to sink in. First do not let Anglia Water do any of the work. If you are a doing a NHBC Self Build then do it all your self. If you are selling the plot on, then revise drainage lay out and...

Sorry for delay.Have good days and bad days. Should be okay tomorrow. Oldun

Did most of post to you. Went back to drawings to check a measure and found your prelim drawings. Our apologies to you for asking questions that we already had most of the answers to. We now note that it is only a w.c. and wash hand basin to the cloaks that is involved with the run in...

If your measurements are correct, converted to metric = 3030 run and 685 rise = 12.7 degrees and slope of 3126. However if you have measured down the slope and not the run then pitch will be 12.9 degrees. You can tell just by looking at slope that it is approx 12 degrees Regards oldun --

We do not know how knowledgeable you are so bear with us. Assume at present this is a private sewer, but will become public sewer when new unit is built. It is just not practical to try and get into existing manhole with new soil connection and you can not drop a new foul into existing...

Your original question was for AAC blocks and that is what we answered. We hate AAC blocks and run a mile away when we see them. Our choice of blocks on new builds or extensions is Plasmor Aglite Ultima They are made with expanded clay pellets and light weight aggregates leaving open textured...

You asked a question, we gave you an answer. You did not like the answer, so use your own discretion. Regards oldun :o

.Would appear that since answering your question, can of worms has opened. Will put you right. Put thin bed out pf your mind. It is as much good as a chocolate kettle. Use a 1.1.6 mix with splash of febmix. Yes AAC blocks are prone to movement and cracking render., however a 215mm block is...
