  1. Thanks Gav. All good points and exactly why I'm posting this to those who have experience, so thanks for the feedback. Definitely exciting... if I can pull it off. Might be a few years off with your estimations though... ? Cheers Moonshine. Absolutely will, but just trying to get a really early feel for whether it's feasible first in consideration of my finances. Posting this to see if I could get some feedback on the breakdown of costs to see where I am way out... and clearly I am in a lot of places.
  2. That's great, thanks Bitpipe. How far does your cantilever extend from the rest of the build? Will add MBC to the list! Cheers.
  3. Thanks for the feedback, Peter. By coatings, do you mean external rendering etc? Would you be able to expand on what might be involved so I can break it down please? I had done some research on piles and looked at other comments on this site for CFA piles to guide an estimation on the cost in consideration of the fact that the section requiring piles is just 30sqm, but appreciate that there are a lot of variables and always trying to 'add a bit' for the fact it's in London. I had factored connections for drainage, water and electric into Stage 1 and allocated £10k in the spreadsheet on line 8. The site sits on the roadside alongside other residential properties and the sewer runs along the middle of the road, so not far to go. Thanks Peter.
  4. Just a minor point I am missing then... ?. How on earth do I estimate that!? Any ideas gratefully received?
  5. Thanks for your feedback, nod. No, not negative in the slightest... I am new to the self-build world and in the very early stages of planning a project so appreciate your comments. I am trying to keep the cost down, but not to the extent of being unrealistic, so all feedback from experience very much welcome. Bathrooms and kitchens I am content with and have experience in from previous renovations, so not too worried about those costs. It won't be anything particularly fancy. I accept your point on windows and the door, but point to note that the garage doors are not mine (although I may end up re-providing them if the build so requires) - they are only to demonstrate the need for access of neighbours who have existing rights of way. I'd love to include a supporting column for the cantilever too, but site constraints mean that it's not looking likely to be possible. Cheers!
  6. Hi, I'd appreciate your thoughts on these floorplans. I'm planning a 4 storey dwelling in London. It's designed as an 'upside down' house to make the best use of daylight in the living areas as it is located in a built up area of London. These drawings are only completed by me having a play around on Sketchup, so no professionals have been consulted on layout, yet! What do you think? Thanks. * Front elevation Ground floor First Floor Second Floor Third Floor Roof
  7. Hi, I am planning a self build project in London which is on a constrained site (11x6m) and initial designs include a cantilever. It's likely that the supporting 'column' will be 5m wide, whilst the cantilever will be 6m, which complicates things somewhat. My question is, can this be done with a timber frame? I have had a few conversations with timber framing companies... one wouldn't deliver inside the M25 (so didn't consider whether it's possible), another said they wouldn't take it on and I am yet to hear back from the others. To note, a supporting column on the right hand side of the building is unlikely to be possible. I'm considering steel frame construction at the moment as those who I have spoken with have all deemed it possible, albeit I recognise the disadvantages of residential steel frames. Have you carried out a timber frame build with a cantilever? If so, would you mind sharing your experience with your timber frame provider? I would really welcome recommendations of any timber frame companies and/or structural engineers who might work in London and you have experience with. Thank you.
  8. Hi all, I am at the very early stages of planning a self-build. The site is in London and is extremely constrained, which means the design includes a heavy cantilever (image below). The site measures only 11x6m total. At the moment, I am considering a steel frame design (mostly as a result of the need to support the cantilever). I am yet to have a soil survey carried out but know that it is highly likely that there is made ground to approx. 3m, superficial deposits to 7m 3and London clay beyond. Structural engineers are advising CFA piles - if you have other suggestions, please let me know. I'm trying to estimate costs to see if the project is feasible but I'm not sure if I've missed anything? I'd be grateful if those with experience could take a look and give me any feedback please? Some indicative costs have been provided by tradespeople and others are pure guestimates, so would appreciate your thoughts. Thanks. Costs Spreadsheet.xlsx

    Hello!

    It would definitely be a challenge for multiple reasons! Do you mean for their insurance, or mine? In either scenario, I don’t think the ‘right to park’ exists, but the right to pass over the land likely does. The plot is in central London, so a car is not required. The site has a very good PTAL rating. Might need more than gold in this instance! The plot is in central London and land in the area is at a premium, hence going to so much effort to overcome the challenges.

    Hello!

    The land is held on a long leasehold. The leaseholders of the gardens behind the plot are the beneficiaries of the rights of way, which is supposedly written into their leases. I will be seeking legal advice on this and I am just making very early stage enquiries to see what might be feasible in the worst case scenario. Even if rights of way are provided for in the leases, my understanding is that does not give rise to parking, but rather just to the right to pass over the land. I say that the parking spaces are more likely to be an issue as it doesn't seem that anyone actually uses either of the garage doors to access their garden, but the parking spaces are in frequent use.

    Hello!

    Thanks Peter. I had considered a column on the outer edge, but it's unlikely to be possible, just because of the site constraints. Will keep it in mind though. The 'garages' that I referenced are in fact just a single brick wall with garage doors in them, which provide access to neighbouring gardens. There will certainly be some time where access is not possible and there will be some negotiation to be had. It's more the parking spaces in front of the garage doors that are the issue that physical access to the gardens beyond. It is! It's in a very architecturally eclectic area with residential and commercial buildings spanning Victorian design from right through to post modernism. Thanks for the comments.

    Hello!

    Something like that... Thanks for this! I have looked through all of these but still haven't found one. My computer won't let me convert those that say to download and convert back to .xls files. I'll keep looking and will aim to share mine when it's complete. Or when I think it's complete, at least. Not yet, but pre-planning advice was very promising!

    Hello!

    Hi, I've read lots of posts and have gained some really helpful tips already, so thank you all for sharing! My site is approx. 11m x 6m boundary to boundary - not much to play with. There are also some existing rights of way across the land to garages which I will need to honour, so it leaves me with an interesting challenge! There is a lot of industrial Victorian architecture around, so I'm hoping to keep a nod to that in the design (although budget might limit me somewhat!). I have been playing around with Sketchup (haven't we all!?) and think I'm finally starting to get the hang of it... sort of. I'm sure professionals would not agree and if anyone knows how to get rid of the lines between storeys or auto cut windows into 300mm thick walls, please let me know because it is starting to drive me crazy. I've added some pictures below and would welcome your thoughts. The intention is that the staircase would run directly up the centre, allowing for a room either side on each level. I am also working to develop a comprehensive project plan, which includes a breakdown of costs. I have made a start, but if anyone would be willing to share any templates for comparison/cross check (specific details not required, I am purely interested in the structure/items to make sure I'm not missing anything), any project plans or spreadsheets would be very gratefully received! I'm at the very early stages of thinking about this project/potential nightmare, so would appreciate all your comments from your own experience. Questions of this moment are: 1) Construction methods/materials... where to begin!? SIPs, timber, steel, block...? I am keen to keep the build as environmentally friendly as possible, but budget will unfortunately have a part to play. Where did you start with considering the options? 2) Does the 'floating overhang' limit my options of construction methods/material? 3) Does the fact the building would be 4 storeys limit my options too? 4) Estimating costs - what are your thoughts on Jewson Aviator? Thanks
