Box guttering with warm roof, is it possible?
Tuppers replied to Tuppers's topic in New House & Self Build Design
We were hoping for a warm roof design for a few reasons: Due to the size of the open plan area and the amount of glass we're expecting to be involved, we were hoping to have it be more efficient to heat which typically warm roof designs are With the propensity for change of use in the space, we wanted (where possible) to have ceiling services run between rafters in the void that a warm roof design can afford. To achieve this using a ventilated cold roof design invariably means lowering the ceiling height by adding battens so if you want to change the position of a light you're not having to dig out insulation Ease of install was also part of the consideration I'd rather not over complicate things however so we'll likely proceed with a vented cold roof design and see about raising the ceiling height slightly before the final plans are submitted in order to allow for the additional battening. -

Tuppers replied to Tuppers's topic in New House & Self Build Design
To your first question, yes, exactly that. I'd looked at forming of gutters in the insulation but I'd assumed that this wouldn't be acceptable to BC as it would lower the u-value in a given location. On the fall direction, it's an ~8m protruding rear extension so the most logical method (and in my mind asthetically pleasing) for a pitched roof is to have the pitch perpendicular to the rear of the house, which is where the issue lies! -

Thanks for the response and I'm glad to hear it! I've tried drawing it out to help me, but I can't seem to work out how you fit it all the requirements in for a warm roof with the insulation sitting on the rafters, for example where the stop battens would go, how the rafters would sit, etc. -
Hi all, The person doing our plans is on holiday at the moment and I wanted to try and get some advice on something I noticed following a comment on my intro post (https://forum.buildhub.org.uk/topic/42202-extension-slightly-large-and-renovation-in-cambridgeshire/). We're on the path to getting planning permission so don't have all of the structural/full technical documents created at this time. I'm very keen to have a warm roof on our large single storey rear extension. I'd not noticed that as part of the plans, there is what I understand to be box guttering placed on top of the external skin wall on the attached neighbours side, thus allowing for the extension to go 100% to the boundary. Would you think this would be possible? I've searched to try and see if anyone has mentioned this before and looked online but not found anything, apologies if there is. I'd appreciate any advice anyone can give! Tuppers

Your total room size is similar to what we're looking at so was really interested to see your design (although you have a lot more glass than we are looking at!). As on your plan, we've been considering having the island with nothing on it, but have also recently been discussing putting the sink there to help with the flow of our kitchen. We've got a pantry/prep kitchen in our current design so was nice to see that in someone else's! One thing I was surprised to see in yours was the fridge/freezer being right next to the oven? I can imagine it constantly spinning up the cooling with the oven on. If you're limited in where you can place things, maybe putting some kind of insulation between the housings to limit heat transfer might be an idea?

Extension (slightly large...) and renovation in Cambridgeshire
Tuppers replied to Tuppers's topic in Introduce Yourself
Yep, it is a lot of work but we may choose to do it in stages. We got a rough price on the original rejected plan a while ago, but with the increase in prices of everything we're looking at doing as much ourselves as possible. We're in a perculiar position whereby we're not living in it, but a family member is, and they're comfortable with work going on whilst still being there (whilst safe to do so). I'm keen to understand your comment and thoughts on the kitchen layout? It's not the best picture as it doesn't show clearly where everything is. Admittedly I've done it based on my wife's thoughts and felt that something was off about it, but couldn't quite work out why. We are planning on speaking to someone about it but I'd love to hear your thoughts in the meantime! -
Extension (slightly large...) and renovation in Cambridgeshire
Tuppers replied to Tuppers's topic in Introduce Yourself
We replaced the entire ground subfloor (asides from the concrete in the kitchen) so I know we've got a good 600mm+ to help retrofit the UFH in the main ground floor of the house, the kitchen (which will end up being a mix of rooms) will be a different story though... On the EWI side of things, there are a lot of council houses on the street and they have all had it done together with solar/solartherm, so a lot look quite odd next to ex council houses that haven't had it, but it's a decision to be made in due course. GSHP was the preference (mainly to save on having an ugly looking thing out the back/front of the house), however, my wife has just given the go ahead to look at ASHP instead! I now need to investigate more about placements/distances from cylinders etc. Idea would be a cylinder in the utility room. I'm hoping to get solar and batteries installed at the same time on a deal of some description, but agreed, we'll get appropriate provisions in for them as I'm really keen to future proof ourselves where possible. -

So as it stands the pre-app plans we submitted look like the below, however there are changes which are still to be added which my post indicated. We've also got a rough plan of the kitchen layout as well which I've included as well Pre-app plans Kitchen plan: -

Tuppers replied to Tuppers's topic in Introduce Yourself
Thanks for the welcome! The manner in which we're planning it means that there won't be major changes to the main fabric of the building, also in an effort to reduce costs. That's the "plan" anyway, whether or not it works out like we hope...! -
Hi all, Really happy to be part of the community having read a lot of things on here and finally at a point whereby I wanted to sign up, introduce myself, and what we (hopefully...) have planned, but a bit of backstory first! We live in Cambridgeshire and bought a 1930's semi detached house back in covid times which we're hoping to be our forever (or at least 20+ year) home for our family (2 adults, 2 kids). We're looking to do as much work ourselves as possible to keep costs down and have done a number of things previously such as full subfloor replacement, rewiring, ceiling replacement, bathroom install, etc. so have "some" knowledge and skills. Due to various factors, we've taken a long time to get plans created. Our planning application was originally denied (we were caught out by the whole terracing effect side of things) and we've since gone through pre-planning with a revised set. From this consultation we're now updating plans in order to resubmit and are hopeful to get approval based on the outcome of the pre-planning meeting and report. I'll post plans once we've had them updated, but the scope we're hoping for is: Large single storey rear extension with vaulted ceiling (~7m x 7m) - open plan kitchen/dining/seating area with concealed prep kitchen area Ground floor side extension out to and following the line of the boundary (starts ~3m wide, opening out to about 3.5m at the back of the original house) from level with the bay window at the front of the house to the rear of the original house - garage at front, utility/bathroom behind it Side first floor extension, set back 200mm from the front of the existing house and 500mm from the side boundary, through to the rear of the existing house - bedroom and bathroom Full dormer loft conversion across original and new side extension, changing roof style from hip to gable - master bedroom, ensuite, dressing room/study Solar panels on pitched/flat roof (front is south facing) Things we're not decided on but currently considering: Replacing existing timber suspended floor in original property for concrete slab with underfloor heating Ground source heat pump with boreholes (very much up for a good discussion on this!) Battery system connected to the solar panels (most likely will do) Externally insulating solid walls of original house Hopefully this all sort of makes sense, and yes, I'm aware this is a huge amount of work! I've got lots of questions about things but am busy reading up on posts first of all so I don't ask any answered questions (where possible), but look forward to engaging with the community and hopefully giving back where I can too. Feel free to ask any questions if you have them! Tuppers
