Timber frame, CPS or SIP?

[AnnaKH]

Hi, looking for some advice on the pros and cons of going with timber frame, CPS or SIP construction for a 1.5 storey rural self-build. Specifically wondering how the various type build affect the future value of the house, and how the speed of construction affects the overall costs (ie if SIP goes up quicker than CPS, does this counter the extra cost of a SIP kit as you’re saving on days of labour?). Any advice welcome!

I think you can achieve everything with standard timber frame that you can with SIPs, and about 15% less cost. Unless you want a passive house, SIPs are overengineering for a house. They also aren’t as good if you want to span openings or have vaulted ceilings. 
 

I’ve worked with CPS a little, I just think most builders prefer to put the finishes on, on site. It probably is a little quicker, but the more people who can do it, the more choice you have. 
 

I don’t mean to be down on either system, but I just think they are too expensive for what they achieve.
