Hello, I am constructing a small shed (3.5m x 2.2m) that will be used only for storage. I want to render the external walls with the K-Rend silicone render to match my outbuilding and my house. I was wondering if you could help me understand what the best way to construct the shed is so that it does not cost a lot and can be rendered. My ideas: - wooden frame + OSD (not sure how easy it is to render over it) - wooden frame + cement board (seems like the way to go) - blocks (seems like a lot more work and expense) any suggestions would be very much appreciated.

Ok, I think I know how it needs to be done. For everyone who may be looking for the same answers: How to construct a floating floor | Insulation | Kingspan | Great Britain

Thank you @PeterW It makes sense. I think I will opt for laminate and some rubber floor in the gym area. This may be a basic question but I have not done it before: Does the DPM have to be glued to the concrete with anything (e.g, silicone?) and then the PIR to the DPM?

Good afternoon, I am building a small outbuilding (30sqm - office and gym) on a raft foundation. The raft and walls are already in place and I trying to figure out the bast floor structure. Currently I am looking at: - DPM atop of the raft foundation concrete - 130mm PIR insulation atop of DBP - 22 OSD atop the insulation - floorboards atop the OSD What do you think about this structure? How would you recommend bonding all the layers together? Any suggestions would be much appreciated.
-
@Nickfromwales I am sorry to bother you again. I am doing the floor now and I am not sure how to bound all the layers together. I understand that I can use foam to bound the sacrificial EPS to the slab but what do I use to bound the DPM to the EPS and then PIR to the DPM? foam as well? Please could you help me understand how to do that?

Hi @nod Thanks and sorry but I am a bit confused. Please could you explain what Rational Who is? MP

Good afternoon, Does anybody have experience ordering Nien Made windows shutters? Is it possible to order them directly or is there any UK company that you would recommend? Or maybe you could recommend a good alternative? Many thanks for any ideas. MP

Thank you @Gus Potter

Thanks @markocosic

Hi @Gus Potter What thickness is your EPDM and what brand did you get? I am thinking about EPDM but I have never done it before. My flat roof stack for a small, 30sqm outbuilding (office, gym, bathroom with steam shoer) is going to as below:

Thank you @markocosic I reckon you are right about the downlights and their suitability for an office I need to really think what lighting would be best for my video calls too. Thanks for all the ideas and suggestions. I still have my doubts about the rubber roof. I will have two 600x900 skylights. Do you think I should go for EPDM? If so, any particular thickness and brand you would recommend? Any suggestions would be much appreciated.

Good morning. I have recently joined too and have already received a tremendous help from this awesome community. You are in the right place.
-
@markocosic I think it will be monocouche render to match what I have on the house.

Thank you @Nickfromwales and @markocosic for all your comments and recommendations. Based on what you are saying, I came up with this picture of my roof: Please, could you help me with the following: For the rubber roof, what product would you actually use and what thickness. I am looking at EPDM Rubber Flat Roofing Supplies | Rubber4Roofs but I am not sure if I am looking at the right thing.... For the air barrier, could I use this product: Powerlon Air Barrier Membrane - 50m x 1.5m Roll | Roofing Superstore®? Or is there any better product you would recommend? Do I need anything between the plywood and the joists / air gap? I planned on having spotlights / downlights as I thought they would be best for the office / gym area. However, I understand that I should not break the air barrier.... Do you reckon that wall washers would be really better? Is there any specific product you would recommend?
-
@Nickfromwales Is there any particular model that you liked and you think it would be a good fit for my outbuilding? I can still change the size of the bathroom as the partition wall is not there yet. I already have the drain in the raft foundation but I can still go with an external drain.

Hi @markocosic Thank you very much for your extensive and solid advice. It all makes sense but there are some constraints now due to certain decisions that I have already made and committed to. Namely: - I have already started and almost finished building the walls using 150mm Thermalite blocks. - I have already bought some of the materials for the roof. These are 47 x 150 C24 joists and 18mm hardwood external grade plywood. - I already have Catnic CN81C 4575mm above the big bifold door. Walls I now need to figure out how much insulation I need on the outside as I am already invested in the block walls. I think that the 75mm suggested by @Nickfromwales is reasonable. Roof I infer from what you are saying that in the roof I could have the plywood, then leave a ventilation gap (50mm), then have 100mm PIR, then airtightness / vapour retarder and then plasterboards. I cannot use wool because I would not have enough space for 150mm of it. I will have a waterproof layer on to of the plywood, of course. Structural Do you reckon I would still need a post and the ridge beam? Perhaps I should do some proper structural calculations to ensure it is all sound.... Floor I like your idea of thicker engineering wood finish. The drain in the bathroom is in the floor. I have not decided on the steam shower unit but I will pick one that drains into the floor. I intend to tile the whole bathroom.

Thanks @Nickfromwales for the extensive guide. It is extremely helpful. I already have the raft in place. I need to check if it is perfectly flat and level. If not, I presume I would need joists? Or do you think I can somehow level the floor on a higher layer? Flat Roof: I am thinking of 6x2'' joists and 18mm external grade plywood. Then 100mm PIR between the joists and plasterboards from the inside. I don't know what I am going to cover the roof with. I started researching EPRM. Any ideas would be much appreciated. Walls: 150mm solid wall (Thermalite blocks) with external insulation (50mm or 100mm). Do you think I need more insulation on the walls and the roof? Thanks for that. I am dropping my silly MVHR idea.

Thank you @Nickfromwales and @Iceverge. You guys made my day. @Nickfromwales - to build the floor, would you just just install joists directly on the raft foundation (with damp-proof membrane laid down first), place PIR between the joists and then 36mm of deck board atop? I have not done it before so I am sorry if I am asking obvious questions.... Also, you both stress on airtightness and mechanical ventilation. Do you think that a single room heat recovery unit (https://www.fastlec.co.uk/blauberg-mini-air-single-room-heat-recovery-unit-with-wifi3) for the office area and a traditional mechanical fan (https://www.amazon.co.uk/gp/product/B01LYTOSBH) for the bathroom would be suitable?

I have started researching air to air heat pumps and I came across electriQ Smart12HP 10000 BTU (2.93kW) Wall Mounted Heat Pump Air Conditioner that is said to be suitable for spaces up to 30SQM. I have seen some positive comments about the appliance on this forum. It cost around £700 which is much less than I thought I would have to spend. Am I being naive to think that this kind of appliance could be suitable fo my outbuilding?
-
Thank you, @Nickfromwales for all the sound advice. I have not decided on the unit but it will be used primarily for steam sauna and short showers. I like the idea of 60-80L wall mounted UVC. When @Iceverge mentioned it, I assumed I would need much larger storage capacity as I read somewhere on this forum that small UVC would be 180L. Yes, this makes perfect sense. I am going to stop considering any wet UFH. Do you mind if I ask what in-screed electric UFH you used? I really like the idea of installing a heat pump and using its air-con function in the summer. Would you know, more or less, what its cost would be for such a small outbuilding? I think I now have to decide between in-screed UFH and air to air heat pump... From what you are saying I would prefer a heat pump with a well insulated floor unless the cost of it is prohibitive for me. Once again, thank you both for your help.
-
Thank you @Iceverge. I understand that with UVC, I will have to have a large tank which I am trying to avoid because of the space that it takes. The bathroom will be mostly used for the steam shower which will come as a unit and I understand that the steamer will have its own heating element. It seem that I will just have to heat some water for quick showers and for washing hands. You reckon it is still worth having UVC?

Thank you @Big Jimbo. I have created a new post here: Heating system for small outbuilding - Garages & Workshops - BuildHub.org.uk Any advice would be very much appreciated!

Good Evening, I am building a new outbuilding in my back garden. I am trying to figure out what the best electric heating solution (CH + HW) would be and I would like to ask you for your opinions here. The outbuilding will contain an office, a gym and a small bathroom with a steam shower unit and a sink as per the plan below. It will be used throughout the year on a pretty much daily basis. I initially thought about using electric heating mats for my UFH and a small boiler for my hot water needs but now I think there may be a better, more cost effective solution. I have seen a number of threads talking about ASHP, Ampec flow boilers and Willis heaters. It made me think about fitting a wet underfloor heating system and using one of the solutions but honestly speaking I am not sure what would be best as my knowledge and experience is limited. I would be very grateful for any advice. Martin

Hello everyone! I came across this forum a few days ago when I was researching possible electric heating solution (UFH + HW) for my outbuilding (office + gym + bathroom) that I am building from scratch. I come from an IT background and honestly speaking I am a bit overwhelmed with the task but after reading the threads here I formulated a few options. I would like to politely ask for your advice on them. I hope it is acceptable if I create a thread that shows my outbuilding plan and what I am thinking of. Many thanks! Martin
