Our build has been spec'd as brick / block. Estimators online have come back with 340k for a 200m2 house with oak cladding / aluminium windows and seam sealed roof. After I have tweaked the numbers for the tasks I intend doing myself and removed the associated project manager, site labourer (runner) I have got the price down to 267k. I have achieved this as follows. 1) Removed the roof installation cost (going on Catnic course as installing myself), 2) Cladding installation 3) Decorators. I can probably shave some more off of this price, as I intend on doing a fair amount of first / second fix carpentry myself. The roof is a simple low dual pitch with no hips or valleys (rafters are only 4.5m), so on reflection that is probably cheaper for me to cut the roof myself as opposed to using the trusses that were spec'd by estimators online. I really do need to pull this build in as cheaply as possible, as my wife and I do not want to have to sell it post construction. We fully understand that we might be doing this build for 3-5 years, but it's our dream plot and we understand that roughing it in a static is a small price to pay to enable us to have a dream home for our retirement. I have digressed somewhat, and what I was really wanting to ask is whether a SIP / brick slip (me installing brick slips) lower build would come in cheaper than if I was to construct with brick / block (labour only brickie, ~ £1 / brick). I could send off for a revised estimators online quote for SIP / brick slip, but I thought someone on here might simply say "yes, it will be cheaper, or no, it will be more expensive" As always, appreciate the wisdom out there.

But surely that would not result in the development having to be pulled down.

I just left mine in the middle of the pavement.

I have a number of conditions that need to be signed off before we can officially start development. Before our app was granted, I dug a trench to have a temporary water supply put in, and I now need to get a hard standing down asap for a static caravan (seen a very tidy one for reasonable money), but will putting down a temporary hard standing for a mobile home fall foul of enforcement or will they be ok about it?

Most helpful. Thanks

CIL exemption form has already been submitted.

Bizarre request given our build is a self build and I'll be projecting managing and only hiring trades when required. Reluctant to shell out more money for some pointless report and was hoping someone could post a link or send me their one and I can tweak accordingly. Thanks

This condition on our granted PP made me chuckle. 3 long and 1 short stay places 😂 The development hereby permitted shall not be occupied until the property has provision within its curtilage for secure cycle parking facilities. The proposed dwelling shall provide 3 long and 1 short stay places. The cycle storage shall thereafter be retained and maintained in perpetuity. REASON: To improve provision for cyclists and discourage the use of the private car wherever possible and in accordance with Policies CN9 and EM10 of the Basingstoke and Deane Local Plan 2011- 2029

I wonder if any of the 'been there and done it' members could maybe help me with what steps I need to take next now that we have PP granted. We need 100% finance for the build, we have 20k of our own, but this is going to get swallowed up on the following items - Nitrate mitigation credit purchase ~ £7.5k (typed with gritted teeth) - Static home purchase (we ideally want to get out of our 1600k/month rental asap and get living on site) - budget 7-9k - Treatment plant purchase and associated drainage field installation (doing this myself) - Electricity connection (3 phase) ~ 3k - Ideally, technical drawings too for building control ~ 2k - Self-Build site insurance There are a few conditions (Radon gas survey ...) but none of them require expensive consultants. So once all of that is done and we are living on site. The build plan is one of two options. To get a quote to provide a shell to plate height (labour and materials) OR I will do the footings myself and then use a brickie on day rate to build the shell to plate. All depends just how much of a difference there is between the two options. I have rambled on, but I think I was asking that to get financing sorted, I require a few things to be done up front? I have received my estimators online quote and it's coming in at £267k. I can shave this down further, as I am going to be doing a lot of the plumbing, first fix and second fix carpentry myself (hence why I want to live on site). But it's the financing / warranty side that I am not sure about. Thanks

Very useful! Thanks

Any update on this thread? I need to get some quotes for our aluminium doors and windows and have absolutely no idea who to use. I think Raynears are really top end, but not sure if there is a middle ground.

A quick update on this. I spoke to them and they also proposed 3 phase.

Ok, I appreciate this ideally requires an electrician, but I am hoping that someone on here can give me an idea. 4 bedroom detached 200m2 two storey property with underfloor heating upstairs / downstairs, EV charging point and induction hob. Aside from those high consumers, there isn't anything else outside a typical domestic property. I was thinking of a specifying 20kVA. Does that sound about right?

But how does that work with regards to the inner skin? Are you saying have a wider cavity on the ground floor?

You were 100% correct. Not one question. All the previous applications each took 15-20 minutes with long drawn out speeches from the applicants. Ours was done and dusted under 5 mins. Even the Chairman commented how my wife’s statement was the shortest of the night. The personable ‘self-build’ aspect to the speech and not mentioning anything to do with consultee objections was great advice! So thanks again.

Thanks. I wasn't aware of the acoustic transparency of the PIR. The one positive I do like of the SIP is around the fact that the cladding can then be flush in the vertical plane of the wall when it adjoins the lower floor brick exterior skin. Having the lower in brick / cavity / block and the upper block / cavity / block, means that the counter batten + cladding (~ 75mm thickness) will sit proud of the lower floor brick face. Aesthetically it doesn't quite look as nice. I don't think there is anyway to avoid that?

I suspect this has been talked about a huge amount, but given I am going to be managing our project and doing the first and second fix carpentry myself I am unsure how I go about costing up the difference between having the upper storey and roof constructed with SIP Vs having it constructed with traditional block / cavity / block and me cutting the roof myself. Exterior of the upper will be vertical timber cladding and the roof is standing seam. Footprint of the dwelling is ~ 110m2 If anyone has recently looked into this and can give me some guidance as to what their findings were it would be most appreciated

Thanks for all your help. We were last in the list of applications, but our worry was short lived. My wife read a short and personal speech regarding this being our dream for a long time. No questions from the committee to my wife or I and none either from the committee to the planning officers. Approved unanimously. Really chuffed and a bit dumbfounded it's finally over. The not knowing what the outcome is stressful. You put your life on hold.

One last question on this. I will find out whether any of the objectors are planning on speaking at the committee meeting tomorrow. If they are not and given the planning officer is recommending the application for approval, would people still suggest we pay for the planning consultant from the architect practice to attend, or are we simply wasting money and we are better off just addressing the committee and asking for their support in approving our application?

Does it basically switch to using an immersion heater to heat the water to 70c? I always thought an ASHP was only efficient at heating water to low temperatures, eg underfloor heating?

Can anyone advise as to the best option for hot water when we are having an ASHP for underfloor heating. I like a good flow rate shower, so was thinking that we should have an oil boiler for hot water. What have others done when you have to have an ASHP?

Our electricity supply requirements are not straight forward. We need to have the pole moved and have agreed a £3k contribution to have it moved to the boundary, but have been advised it can take 12 months. We obviously do not want to wait 12 months before we commence development and therefore require a TBS, so that we can get started and have a mobile home on site. I am not sure how many KVa we need for the house (we are having to spec ASHP, EV chargers). There is no mains gas. But obviously, the TBS can be much less. What do people recommend here. Generator for the mobile home or have a TBS put in, but will need to be eventually moved when they move the pole?

Thanks for that. I was just reading about the audibility related issue.

Incredibly frustrating and local councils should face higher compensation costs for going against the planning officer and then losing at appeal. It might then remove the politics that should not feature.

So our application has been spec'd with a Graf One2Clean. On reflection, I would like to potentially switch this to a Tricel Novo, for the simple reason that the required excavation depth is considerably less than the Graf. The Tricel does look like a quality offering as well, and I like the fact that you can house the compressor inside the lid of the tank. I suppose that I would potentially have to have the calculations redone and the nitrate offset credits might need to be recalculated? Has anyone change their tank from the one spec'd in their planning application?
