ᐅ Comparison Between Architect and General Contractor or Turnkey Construction

Hello everyone,
as is well known, general contractors or construction companies offering turnkey houses usually charge a certain percentage of the house price (in my experience 10-15%) for taking over the warranty, the risk of cost increases, site management, coordination of trades, and so on. The costs for an architect are in a similar range, but in my opinion they also offer additional advantages such as tendering the trades, independent site supervision, and ensuring that exactly what was planned in the design is carried out. A disadvantage might be that you don’t have a fixed price. Therefore, my question is: why would one choose to build with a general contractor? Am I missing something?

Thank you very much and best regards

that you especially have the advantage of having an independent and detailed construction supervision
You can get that with any project (except from the developer). Either you pay the architect for it or your own expert with the general contractor. So no advantage when it comes to an architect-designed house.

Sorry for the late response, but in our case, we already have a design from the architect that we want to implement, meaning the general contractor (GC) will also have to build it custom for us. Now I’m thinking about what happens after phase 4. So, I wouldn’t be wrong in my assumption, right?

I’ll start looking for related discussions.

So the main costs for the architect will still be incurred — or at least for the GC. @11ant has several posts about the next steps.

In the end, the house will cost more or less the same. However, with a GC, you’ll have very little opportunity to influence additional custom requests that come up during construction.

But I would have to pay for that separately again....

You will pay for it anyway – it’s part of phase 8 services with the architect or an expert during construction with the general contractor (although the expert’s fees are only a fraction of the architect’s – the architect accounts for about one third of the total invoice, since many trades need to be coordinated and supervised).

So the cheapest option would be to do phases 1-7 and then have an expert inspection, right? However, the inspection might not be as effective because the expert would need to spend a lot of time familiarizing themselves with the detailed construction plans. Would that be acceptable?

Cheap yes, but not practical.
Phase 8 involves much more than just supervision:

If you have the professional skills and time to handle the most challenging part of an architect’s responsibilities and only need a third party to check quality, then you can do it that way—for example, site management, invoice verification, etc.

For me, that’s a no-go—see above.
