    when do i need Quantity surveyor and/or construction plan?

    Hello all,

    I'm planning to fully renovate a house, turning it to a 4 bedroom HMO
    The renovation will include fully refurbishment of the house internally and externally, upgrading the kitchen and WC's, wiring, heating system etc.
    The building costs will be around 30-35K.
    Currently my builder based his costs using the detailed plans used for building reg control, but i'm worry that calculating building cost only by visiting the site and using the detailed architect plans won't be accurate.
    Should i need a construction plan from the architect for this scale of work?
    Should i need a Quantity surveyor or it is too simple project for that?
    Should i use JCT contract with dated work millstones with Liquidated Damages clause or it's a bit overstretch ?

    Is the project's size o determine if i need Quantity surveyor and construction plan? are there any other considerations?

    Thank you,

    In my view everything you mention would be overkill for what sounds like a fairly simple and (comparatively) low-cost refurb. I suggest you simply agree a clear scope of works and staged payment plan with your builder.

    Are you (/your builder) sure that you even need building regs approval for this project? Even if you do, most builders would probably just use a building notice rather than full plans approval for a project of this size.

    I don't mean to be patronising if you've already covered this, but I would check your council's HMO standards and also get advice from a professional fire risk assessor before the renovations start if I were you, in order to ensure your spec meets the requirements of both.

    • Chimney Removal from the roof
      As a part of roof renovation works we want to remove external part of the chimney (above the roof line). The house is semi detached, the chimney is located in the outer part of the house and is not part of any party wall.
      The condition of the chimney is quite bad and we prefer to remove everything...

      That's right!
      We are only removing the part above the roof line, and the example recommendation from leaseholder64 might be more applicable when some parts of the chimney would be removed from inside of the house, which is not the case.
      Many thanks you both for a prompt reply!

      Well reading that document I see no reason to talk to Building Control at all! All that is being proposed is removal of the top of the chimney to below the roof line. As long as suitable ventilation is provided at the new 'top' then just get on with it.

      I say this from having researched...

      Building Control definitely needs to be notified, see, for example, https://www.tendringdc.gov.uk/sites/...20PDF%20V2.pdf

      I would have a word with building control Demolition work tends to be notifiable and the change in weight distribution may affect the structure.

      I'm not sure about planning permission, but I don't recognize it as being a permitted development.

      You may well find that a photograph...

      First thing you need to find out is whether the property has any right of access over either the driveway or the pub car park. Presumably it has a right of access from somewhere?

      Damp Proof Course what have been your experiences with applying for planning and listed building consent for a modern damp proof course where there is not one already and the groundfloor flat is damp?

      Yes agree with you leaseholder 64 however the leaseholder was told by his surveyor that a DPC would do the trick so to speak however this advice can not be followed as listed building consent is required which would not be given as a modern DPC for a listed building would be a BIG no no and seen as...

      Is the lower part of the wall at least 150mm above ground level? If not a DPC is not really an option. (I'm not quite clear about the ground is higher sentence, but it sounds like it means that the damp wall is below ground level.)

      In any case, my feeling would be that, on an old building,...
