It would need to be 350mm which is our fall back

Here’s a clearer more concise drawing

The redesign going under the property actually shorted the runs considerably and allows much more flexible ratios for the falls but I’m not a drainage expert so was just more dubious with having the main fouls drains under the property rather then around it

we want to avoid any drainage works outside the boundary of the property due to it being a private estate and the costs/lenght of time taken to get permissions to dig the road

It’s not to scale the drainage and man holes positions just a rough sketch of location we have added the additional manholes at the front and back so if needs be it can be rodded externally

Hi thanks all for the reply. the number of Inspection chambers or manholes will most likely be reduced to 4 so ignore all the noise on the above drawing this was my rough sketch. it was redesigned due to being short on fall. We are on a private estate so to connect on to the road isn’t an option due to the cost and also the time it will take to get the various permissions. the fall worked fine with the bungalow but due to the property being larger we are pushing the connection to the boundary of the property which gives us about a 1:80 fall only just but the inspector has stated he would be much more comfortable with a 1:60 which is achievable by shortening the runs and going under the build

Hi we are currently at foundation stage and having to rework our drainage design, mainly as we demolished an existing bungalow and wanted to use the same connection. In hindsight we should have dug a trial hole to existing connection and worked the falls backwards, however we relied on some old drainage plans which turned out to be a few 100 mill out leaving us with a very tight fall or having to raise the finished floor level by 300mm to gain the fall. We had a review with our building inspector who decided shorter runs under the building to get the fall to work. I have attached the image and the blue lines are our new proposed routes. Ideally I wanted as much of the drainage outside of the building as possible but looks like this isn’t possible. Any thoughts or advice positive or negative would be welcome

We have no restrictions or conditions on our ridge height in the planning approval. we have no adjacent houses as it’s a detached property on a fairly large plot the neighbouring property is about 20 metres away and the road slopes down. no street elevation was requested or provided for the planning application. we are still going to be lower then the nearest adjacent neighbours house due to the road being on a slight slope. We had a topography survey done of the exiting bungalow which shows the FFL of the bungalow. We are going to be just under 0.2m higher on the new FFL if we decide to go down the route of raising to make the drainage work (we are looking at alternatives with the drainage also). the property size/dimensions/height relative to ground level will remain unchanged and in accordance with plans. the FFL is being increased potentially for technical reasons for the drainage falls to be with in tolerance. I will look in to the drainage speak to designer to see if shorter routes can help

Hi I have a query on tolerances when it comes to build height of the property. we are demolishing a bungalow and rebuilding a 2 storey property. We want to use the existing drainage connection. we have connected foundation and the Finished floor level will need to be approx 200mm above where we previously set out our FFL to get the drainage falls to work. Ive looked through my planning and there nothing in terms of ridge height or finished height of the property apart from the submitted elevation drawings. my question is would 200mm increase in height cause a problem for planning? Or should we look at other methods to make the drainage work like a new connection many thanks

My plot was valued just under £800k. i was released circa £510k which was my max draw down of 65% I used this to clear my previous resi mortgage and pay for warranty and initial site enabling and Groundworks. i will be at block and beam (at a push first lift) when I request the second draw down. my end value has been conservatively placed at just over £2mill and my initial valuation report stated wind and water tight would value at 1.5mill Im restricted to max 65% draw down. my ideal scenario would be by end of 1st lift they value at £1.2 mill this should carry me to shell stage with roof covering complete and then just windows and doors to fund myself.

Did you find the valuations were sufficient to progress your build? my only concern is they deem the valuation lower then the funds needed to progress to next stage

Hi anyone with expertise with ecology stage valuations and draw downs? they don’t follow typical stages or give a clear indication of how much they will release at each stage only that they will release funds as the build progresses. i have a mortgage that will release up to 65% of the value at any one stage. i drew down the max 65% of my plot valuation to clear my previous residential mortgage (knock down and rebuild) and this left a small buffer to commence the build. i have enough funds to get to foundation and block and beam using the buffer and personal savings. im planning on then getting them out to value and release funds. The question is will they release enough to get to the next stage! And what stage would I then be calling them out again? my build is quite heavy in the earlier stages up to wind and watertight and would be great if I could budget effectively .

Hi all hope you can help. we have just demolished a bungalow read for rebuilding a 2 storey house. my mains water meter is just on the boundary of my property at the main entrance to the plot. my builder disconnected the water and has setup a temporary water supply from the main supply. We didn’t get the utility company involved in this. the new property is going to be roughly in the same position as the bungalow and we will need to arrange the water reconnection . Will my builder be able to do this? He has asked for details for the reconnection so im guessing I provide him with where I want the new main stop cock to be? he will be able to dig the trench and lay any pipework? do I need to get the utility company involved at any point many thanks

How do I put this forward to building control that we already have fibre broadband at the site?

Hi all, I am commencing a bungalow demo and house rebuild on the same footprint. currently have fibre to the premises fast broadband to the bungalow. openreach have come out to temp move my fibre cable and box from the bungalow to the site office. once build complete they will re route back to the house. currently overhead cable. for building regs is it suitable for me to explain the above? or do I have to go and pay the £2k fee to openreaxh as this is what they quoted me when I registered the site as a new site on there portal makes little sense to me to be paying £2k to get service to a sight already served by fast fibre
