Temp

If not too late I recommend Zinsser paint on bathroom ceilings. Very good at preventing mould above showers if you like them hot and steamy.

No you should probably choose.. 3. MIxer Shower or 4. Digital Shower (Provided the maker allows use with a combi). Not a recomendation but Mira do some digital showers for use with a combi boiler.. https://www.mirashowers.co.uk/showers/digital-showers/products/?installation-type=rear-fed-dual-outlet

There is a guide to the party wall act here... see page 19.. https://www.gov.uk/guidance/party-wall-etc-act-1996-guidance If you are digging within 3m of their building you only need to worry about the party wall act if you are digging deeper than the bottom of their foundations. As I recall if you dont go deeper than theirs you dont need to do anything at all. On the other hand if you are going deeper then its going to get expensive as they can virtually force you to hire upto three surveyors. So if their founds are right on the edge of your property dig a trial hole to find out how deep they go. Photograph the hole with a ruler in it so its clear how deep they are. Tell your builder not to dig any deeper and tell your neighbour the Party Wall Act does not require you to do anything because you are not digging deeper than their foundations. The other thing to note is that there is no penalty for a breech of the Party Wall Act. However they could try go to court and seek an injunction to get you to stop work until you have complied. Likewise if you were to damage their building the judge would look less kindly on you if you also failed to comply. But as i said above you will comply if you dont dig too deep.

I had a look at the planning portal and couldn't see a dedicated link for submitting an application to discharge. All routes seem to lead to either... Start new application or View your applications (requires log in) So I can see @mania 's problem. Which did you go down?

13 years ago I had several to discharge. I just wrote a letter to the planning department citing my planning reference no, listing the conditions by number and what had been done about each. That and a cheque for the fee was all I needed to send. They replied confirming all but one had been discharged. Perhaps things have changed since.

Perhaps I missed where you did the conversion but you need both in kg. Eg SHC of air is 1012 J/kg.k

In our case one bedroom is silightly hotter later in the day because it has a west facing roof and window. It's why I suggest sleeping in another room to see if the heat source is definitly from you.

If its any help there is a makers installation vid here for heat sealed shower flooring.. https://www.youtube.com/watch?v=M_e9ImlUMiU Looks to me it should be floor first then tile down over the upstand or the sealing applied at 16:07. Are they still moving? I think as a precaution I would board over those before tiling. Behind tiles I would use Waterproof/Water Resistant plasterboard or a cement board like Hardi Backer Board. If he's putting vinyl on the walls as well then might not be so important.

I'm kinda surprised your body energy raises the temperature so much. Have you tried monitoring the temperature in there while sleeping in other rooms?

A garage is considered a fire risk so both walls and ceiling must be designed to prevent fire spread to the house. For example when there is a bedroom above a garage the floor/ceiling between the two gets special attention (two layers of plasterboard i think?). Its different between a room and a loft in the house. I don't think that needs any special treatment.

They are very unlikely to find out unless someone complained. Then the planners may come and take a look. As its only very slightly taller they may decide to call it 2.5m high and go away. If they were real jobs worth types on a mission they may ask you to make a retrospective planning application so they get the application fee. In theory that planning application could be refused but I think that would be extremely unlikely unless there are other factors that mean it doesn't meet the permitted development rules (eg more than half the original garden built on). I believe the skylight would count towards the overall height but I'd still go ahead with that if it was me. How big is the floor area? Have you checked if Building Control Approval is required?

Welcome to the forum.

+1 If its a proper MVHR system the only two ducts to the outside are the inlet and outlet and both go to/from the heat exchanger unit. Thats normally in the loft remote from bedrooms if possible. Ours is in the roof of a porch by the back door. Our Inlet and Outlet point vertically downwards under the eaves. Keep the inlet well away from any boiler flue. There are also .. Fresh air inlet ducts from the heat exchanger to bedrooms and living rooms. Stale air extraction ducts from the wet rooms (kitchen, bathrooms, WC) to the heat exchanger. If you have a vaulted SIP roof some of these pipes may have to be visible internally? or perhaps hidden in boxing or behind a false wall? Some planning required.

Buiding Control will normally want to see evidence the beam has been specified by a professional. I would see if your mate knows an SE or get the Architect to do it.

Has the planning officer said you must do what highways have asked for? They usually but not always do. You could try asking the PO if he agrees with HA or if he thinks retaining the "wild flower verge" is better?

There is guidance from the government to planning officers here that has links to the legislation.. https://www.gov.uk/guidance/ensuring-effective-enforcement#planning-enforcement--overview There will also be a lot of "case law" by way of appeal decisions over the years.

Normally the planners have 4 years to initiate enforcement action. However where the breech involves a change of use (eg agricultural land to residential) then that increases to 10 years. After those 10 years has passed they cannot make the owner remove the building. But the building doesn't gain Permitted Development rights so its harder to extend or replace with something bigger. If it was a mobile home then the owner effectively gains the right to continue to live in a mobile home on the land. There is no automatic right to replace it with a more permanent building.

Converting dormers to gables can make a house look much bigger in elevations even though the floor area is similar or unchanged. If this isn't the problem i think I would press on with the application and appeal if necessary. I've not heard of the planers ever trying to significantly reduce the size of a house compared to an existing house. I suppose it might have happened when a house was knocked down before making an application to build new - because then there isnt an existing house anymore.

Just finished running a scarifier over my lawn. Think I managed to get all of the grass out of the moss ?

Ah OK. I've tiled a small roof onto battens myself and it can be a bit of work planning and setting out the tile battens. I can see it would be easier if you can just nail them on anywhere.

50mm is the normal spec for the ventilation gap on a cold roof. Not quite sure why you need sarking boards on a SIP roof? I know they are more common on traditional roofs in Scotland but isn't that for structural reasons? Don't the SIPS already deal with this?

I did a quick breakdown of what I might expect the materials for the outside stack option to be.. this is very rough estimate. I'm not sure what the input valve would be for. Above ground.. 110mm 12m black soil pipe - £50 110mm branch (2?) - £ 30 110mm 90 degree bend (2?) -£20 50 mm 3m black pipe for bath/basin - £ 10 Assorted 50mm bends/connectors (?) - £10 Cap/cage for stack £3 Underground... Rest Bend - £ 10 to £20 110mm 6m Brown soil pipe - £20 110mm bends (2?) - £ 20 110mm plastic to China coupling - £5 Bulk bag gravel ? - £40 ? Cement to support rest bend? Yes I could see the materials being £250-£300. Perhaps a bit less if not all the bends are required.
