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 35-40K according to my builder, who 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.

usually an architect draw two types of plans:
1. detailed plan - for planning permission and for building regulation control
2. construction/technical plans - for the builder - which currently i don't have

on which kind of project should i need construction plan and/or Quantity surveyor ?
is this based on it's size, complexity or should i require at least construction plan in any case?

Thank you,

2. construction plan which is more technical used by a builder
