Hello, my name is Sebastian, I’m 38 years old and I come from Barth in Mecklenburg-Western Pomerania.
We have the opportunity to take over my girlfriend’s grandmother’s house.
It is a 1.5-story terraced house with a pitched roof, built in 1954, located in Zingst on the Darß peninsula.
Key data: built in 1954, exterior dimensions 8 m x 8.5 m (26 ft x 28 ft), gable ends facing north and south.
Personally, we would prefer to renovate the house to meet energy efficiency standards rather than build new, but right now we are unsure how to proceed.
We would like to first assess the feasibility and potential costs and see whether the loan would fit within our budget (you also want to enjoy life).
The house has 38 cm (15 inches) thick walls with about an 8 cm (3 inch) air gap between them.
Windows, roof, and heating system (gas) were renewed in 1993 right after reunification, but are probably no longer up to current standards.
The facade was newly plastered in 1995, but without any insulation.
We envision an extension in timber frame construction to expand the living space by approximately 8 m x 2 m (26 ft x 6.5 ft) on the southern gable end.
-Plans include reroofing with new insulation,
-Adding 2 dormer windows,
-Insulating the facade or injecting insulation into the cavity wall,
-Replacing the gas heating system with a new underfloor heating system and an additional fireplace; complete new pipework and radiators,
-Photovoltaics?
-Completely renewing the electrical system,
-Replacing the wooden floor with a more solid floor covering.
Has anyone here had experience with this kind of project and can offer advice on how they started? Any help would be greatly appreciated.
Best regards,
Basti

Well, where the mayor and the shooting club champion is the same person, there might have once been an informal approval for an extension sketched out on a beer coaster.
I am also quite certain that using the existing building won’t result in significant cost savings – but considering the requirements presented, I can easily imagine staying within budget by opting for a new build (with the added benefit of having a connection to the house).
I believe the property boundaries shown are the result of a subdivision agreement. Formal building encumbrances regarding setback distances may still need to be established.
My overall "assessment" is still pending photographic material.
Beyond taking a very close look, I can’t really "work magic" here.

You analyzed the building fabric so thoroughly and carefully,

At least he was on site, and some information was probably shared verbally. I think the 180€ (about $195) is reasonable. If you want to buy a property and ask a building inspector for a rough assessment, you’ll also pay a three-digit amount. But then you don’t even get anything in writing.Yes, of course he was on site, and not paying is out of the question. However, I had expected a somewhat more detailed breakdown, at least a few more points in each category.
For example, Heating: - complete rewiring of the pipes including the chimney and condensing gas boiler, etc.
Something like that.

Something like thatI would simply call politely and ask. Something like, "We didn’t quite understand some of the items; does that include XYZ?" That’s what I did with our architect when in doubt.
I would also address the calculation errors with him in the same way and ask. The image you uploaded looks like numbers in a screenshot of an Excel (or similar) table were changed afterwards—was that done by you or by the architect? That could be a possible source of error.
Oh, and one more thing I noticed: the cost estimate lists "own work" without any amounts. You should at least calculate the material costs for that yourself.
SebastianDr23 May 2018 10:50Yes, he entered the values there, but only placed them at the top. Now I can click on them and drag them to the side, and below there is different information. Under the date field, something from 2016 appears, and under our address, there is also a different customer.
Well, from a technical perspective, this is somewhat weak – how old is the architect? There is nothing inherently wrong with including older projects and experience (ours almost completely extrapolated the initial cost estimate from invoices of other projects). You just need to find out whether the content of the estimate makes sense and if everything you mentioned (windows?) is accounted for.
If he has basically given you a reference freely, you could ask that client about their experience with this architect.

In the depths of spreadsheets reused as templates from old projects, there can sometimes be more data than intended (which can also cause errors in a calculation spreadsheet). Either way, the service is reasonably priced, even if it didn’t quite meet your expectations.
