Paging @reef-finance.
So, I reverse-engineered the PDF (on the first try: so much for precious and confidential IP, eh). Their numbers and method make sense to me.
How is the architects’ proposal doing versus our “+/- 10%” decision?
I tried and plotted the price per m2 in their proposal against the “+/- 10%” criterion decided by the plenary, and the result, in visual form, is this:
- Average casco price assumed to be 3,500 EUR per m2.
- The blue line shows prices per m2 of each unit in the Reef, starting with Obelix (10 units), then Asterix (8 units), then Idefix (6 units).
- the green and orange line show prices of 3,500 + 10% = 3,850 and 3,500 -10% = 3,150
Most units are within the range. Two units in Obelix are more expensive; One unit per each of the building are cheaper, with two more units only slightly cheaper in Asterix.
Tentative evaluation
So, at a first approximation, the proposal by the architects has several advantages:
- Criteria for pricing agreed with the group.
- Consistent with market value in case of resale.
- Quite some diversity.
- Most units in the range, even when looking at casco (see below for a discussion on finishings).
Even units that are not in the range are made mostly cheaper. The only disadvantage is that households with their eyes on the most expensive units (O8 and O10) might not have planned for the extra costs.
What about finishings?
Finishings are left out of the previous calculation. This means that – assuming equally expensive finishings – the variation on the inclusive price is going to be smaller. For example, if you imagine to add 800 EUR per m2 to all prices the result of the simulation is near-perfect (except O1 and in part O8).
In light of the above, Team Finance proposes to accept the weighing suggested by the architects, and stored here.
@Lee, I see that on the agenda this shows as “exploration”, but the way I see it we could attempt to consent to it as well.
