Wren was it ..?? ?

kVA is (Volts (230) x Amps)/1000 Most houses have an 80A or 100A supply on single phase. Go to 3P and you can reduce that as long as you can get diversity on the phases and not have the issues of needing more than one phase in the house which needs to be very well designed. 3x80A would be plenty assuming House 1P, Cart lodge/workshop/outdoors 1P, EV chargers 1P So thats a 240x230=55kVA supply.

Sorry @WWilts you still haven’t answered my question !! Has your sewage service provider agreed this approach...? If you connect into that existing lateral connection then the law states the sewage provider takes responsibility for it from the point it supports two or more houses. That means it has to be adoptable, and of a standard they require. If not, you need to make it to their standards. In certain instances they may also insist on a primary connection to the sewer network, but they will advise. None of this is planning or building regulations approval related, you need to get the sewage provider approval first.

So have you discussed / advised the sewage provider ..?? what is the sewer depth ..??

Has to be buried min 600mm. Depending on the tree type you may want to look at moling but in honesty I would be going down the west boundary and then going into the sewer directly or using the lateral drain. Have the sewage company been informed ..??

So as @Russell griffiths says, it doesn’t need to go direct as long as you try not to have dips in the pipework. It will be in 50 or 63mm MDPE and can go whatever route you want.

Which pipe are you talking about ..? The pump out to the main drain of the other property ..??

Try Trojan Baths. UK made, use Lucite sheet and can be sprayed too but they are very well made even at standard thickness. https://trojan-baths.co.uk/trojan-baths/#double_ended_baths

Ask Fischer Future Heat about how to create more efficient radiators using resistance heating ....

Texecom can run GPRS via an addon, and also has voice dialler ability. Most alarms these days are deterrent rather than active security feature so its how much you're prepared to spend in the end.

Ring is...... OK But it can't be installed to meet the Class 2 requirement and its more expensive than Texecom Lights..? Use Shelly - £12 and fire / forget and can do dusk / dawn etc and fit in the back of a switch box Ricochet is very clever as it creates a mesh, and you can see the mesh on the laptop and how it covers the property. Also do a very wide range of products including sensors/PIR/Fire etc

5 houses in 7 months..? And this hasn’t started yet ..? I would expect unless you have money to throw at this then you’re off by 4-6 months.

Ricochet is wireless. And it’s the unit of choice for a lot of installers. They can be installed as full class installs with screws in the correct places on the sensors.

+1 to Texecom Ricochet. Easy to install (watch the YouTube videos..!) and really neat.

Only if you’ve got a HP coil as an ordinary coil will not transfer heat as fast. And you need additional expansion vessel etc so price up the difference - it was over £200 for coil and other kit last time I checked which is a lot of antifreeze !!

70mm insulation doesn’t meet building regulations under a floor unless it’s something like Aerogel. Minimum with PIR and a square building is 85mm.

So bare regs ..? But not taken into consideration you needing to offset the glazing ..? And yes, 260 can be done in layers - how deep are the rafters..??

@jack did they work out of the box with Ethernet ..? A lot have to be overriden to use the Ethernet if it’s available and reset to WiFi when power is lost (LG for example) so only use it as a backup. Happy if they are available still but the focus seems to be more and more on WiFi enabled which is frustrating and as you say leads to more issues.

Agree - but these are paper comparisons which I don’t get being so different ..??

WTD is 48 hours average over 17 weeks. I know a lot of trades doing 7:30-6 with 30 mins at lunch Monday to Thursday then doing 7:30-2 on a Friday. That’s only 46 hours - equivalent to 6 “ordinary” day week - but it’s still within the hours. Some of the lads are on overtime after 37.5 so getting 10 hours at time and a half is financially very good for them.

That doesn’t make sense. UValue for a wall is made up of all the elements. If it’s the same timber fraction, same insulation and depth then the uValue is the same...! How much of a premium is prefitted vs on site ..?

So insulation in a factory isn’t machine cut - it’s cut and installed the same way you can do it on site. You can also foam and tape gaps to get a decent finish. What’s your reasoning for going timber frame if your experience is brick and block ..? Speed to market ..? It’s only cheaper if you have to complete to a short timescale. And I wouldn’t use a couple of your shortlist - big doesn’t mean best in the timber frame market.

Can I take from this that this is your first development ..?? I’d research your suppliers a bit more - also don’t discount on site insulation as you may be better doing this as you can see the attention to detail. It may not be as quick but get the frame up and the roof on and then let the frame settle and you can insulate and get airtightness done on site with very good results.

@Haku out of interest what uValues are you targeting ...?

Most Smart TVs now only work on WiFi so unless you have SkyQ (and specifically ask for it to not have over Wifi connectivity) then a single port is fine. Agree with @jack about PoE, and also consider running to a couple of centralised wall or ceiling locations to fit PoE access points. I did see a faceplate a couple of weeks ago that gave 2 access points from a single cable but it used all pairs and you would need to be very careful about not putting a PoE injector on that cable ..!!
