ᐅ House Construction – New Build Process Plan

Hello,

We had our house designed by an architect, and the floor plan, structural calculations, etc., are all finished. We want to collect quotes from different companies ourselves to save costs.

Could someone provide a step-by-step plan indicating where to go first and what needs to be considered there?
Thank you in advance.

Best regards

Who prepared the tender documents?

There is no single schedule that you must follow. Initially, you should address the official requirements such as the building permit / planning permission, drainage planning, etc.
At the same time, you can start collecting quotes.

Who is supervising and coordinating the construction project? Surveying, setting out the building perimeter, utility connections—these are all minor details but need to be organized and coordinated.

It sounds like you have little experience in construction and need to save costs. That is not a good approach.

The question of where to start sounds like you want to contract all trades separately? Or are you planning to hire a general contractor after all?

Which project phases have you completed with the architect?
Do you already have the building permit / planning permission?
Why don’t you continue building together with the architect?

You can’t have both: either you’re a beginner, or you successfully save money by obtaining quotes. A tender process is like navigating open seas – there are too many sandbanks and icebergs for someone who’s only used to pedal boats. Methodologically, it’s impossible without experience. For a first insight into “saving,” I recommend looking up “time-based billing.” This can end up costing you a lot more in hidden extra hours if you combine two factors: 1. missing detailed execution plans, and 2. lack of experience in scheduling. You have the choice between paying the architect’s fee to prepare not only the permit plans but also the detailed execution plans and construction supervision, or paying the same amount in “lesson fees” for the foolish attempt to do it yourself. The same principle applies to the tender process. When working with an architect, you spend the amount they charge – which is known and fixed; without an architect, you risk spending an unpredictable amount – with a 1 in 5 chance of saving about 3%, and a 1 in 20 chance of saving about 5%. Only very naive gamblers try this. First-time builders are very unlikely to save money by managing their own contracts and site supervision.

Doing this just to save costs is not a good idea. However, if quality is also considered, it makes sense.

Logically, work from the ground up, and infrastructure before finishing.
1. Earthworks / Excavation
2. Structural work / Carpentry
3. Windows / Doors
4. Roofing
5. Electrical installation
6. Plumbing
7. Tiling
8. Flooring
9. Painting
10. Landscaping (Garden and Landscape Gardening)
If you have an interior designer: involve them first.

Tips:
1. Don’t hire anyone who doesn’t enjoy their job or whose team creates conflicts or a bad atmosphere.
2. Choose people who are enthusiastic about your project, not just interested in your money.
3. Allow your contractors to earn a fair profit margin. These slightly higher costs pay off many times over in quality and smooth construction progress.
4. Find someone to coordinate the construction schedule. For us, it was the carpentry company.
5. As a layperson, learn to ask many questions but ultimately also learn to trust.

In a case like yours, yes—if you invest more passion, for example, by searching for the most attractive balcony railing. But in the level of quality usually meant here, I don’t see it that way; on the contrary: evaluating quality statements in quotes often falls into known traps like "according to standards / building regulations / construction code," where a layperson mistakenly assumes a royal quality seal but, in reality, it usually just means "no better than absolutely necessary."
