Well, every draft – no matter how bad – includes the wishes of the TE. In that respect, you almost never start from scratch here.
Of course, you don’t start from "scratch," but a second attempt at a preliminary draft crucially begins with "zero residual burden from vaccination with remnants of a failed predecessor." You don’t try to further process a collapsed soufflé, you don’t make stock from oversalted soup, and moldy bread has no place in a meatball dough. You begin phase 2 of the service with the insights from phase 1 (and the financing advice) about the framework conditions and the space program as well as a list in which needs and wishes are separated like egg whites and yolks. After all, house planning is not a party game like lead pouring, and most prospective builders depend on a methodical approach for budget reasons.
Yes, it sure would be nice, but most builders can be glad if anyone advises them at all. 99% of drafts come from the bottom left drawer with three lines and something glued on and are senselessly bloated without really creating their own concept. The kind of advice from an architect that we dream of is only realistic from a budget >1 million onward.
99% of prospective builders can’t afford senseless bloating at all; a concept-free approach (especially self-award of contracts as first-time builders) is a surefire way to spiraling construction costs. A clear three quarters don’t need an individual draft in the sense of a unique ball gown, which is why I prefer to go hunting for suitable realizations with preliminary drafts for my advisees (unfortunately, some already come with drafts).
Your version of the preliminary draft with days of consultations and monthly maturation phase remains, in my opinion, a utopia for the average builder.
The architect meetings for a single-family home for an average family (2 adults, 2 children) of 130 to 160 sqm in total last a maximum of half a working day throughout the entire phase 2; larger or with a granny flat correspondingly longer. The dough resting time of ideally about six weeks is a period, not working time. It is a mourning period for letting go of surplus ideas and a reflection phase on how well one evaluates, among other things, the “chemistry” between the building family and the planner. The architect is the witness and godparent of the own home. During the dough resting time, the independent building consultant makes the key decisions, the results of which are then taken back to the architect to develop either phase 3 or the entire “Module B.” The result of the dough resting time with key decision-making consists not only of the building method decision (aid) but also alternative building proposals. The architect therefore does not necessarily have to automatically further develop the individual preliminary draft, but the basis of their further work is often an alternative building proposal (type house, catalog draft), which is then adapted by knowledgeable and client-partisan hands (i.e., not by the contractor interested in getting the contract).
I describe here my approach as a building-method-neutral advisor. I regularly mention several colleagues with a focus on "prefab" houses or even specialization in that. In their case, the element of “key decision-making” naturally falls away; otherwise, you must inquire about their usual procedure directly from them.
Speaking purely in terms of house prices / construction costs plus outdoor facilities, those in the 400k group dominate among my advisees over those in the 500k group. Millionaires are also among them, but especially they do not want to spend any money on planning failures at all. “My” architects are therefore not least cast according to budget adherence, “ warns” that blowhards are none of them. After all, prospective builders could also look in the industry directory themselves.
