Hello,

The server behind lovskog.com has supported me for many years, but it has given up. Unfortunately, I naturally have no backups, but I am working on it and will have it all fixed soon.

However, I can say that I am a bit skeptical of the claim that 3 inexperienced people can build a house in 14 days that is also two stories. At least not 3 inexperienced ones like me.

Additionally, others involved were skeptical about the whole thing at first, until I could demonstrate that the other person who was going to do the bricklaying had actually been doing so for 40 years.

It's not difficult, but it requires a lot of practical skill and experience to get angles and walls straight and even. A lot of factory-made elements that need to fit afterwards.

The house was built with lightweight concrete, delivered by Yxhult. The house is a single-story with a T-angle, and it took, as mentioned, 9 days from sunrise to sunset in April 2000.

The biggest problem was renting crane trucks and other larger machines to lift some bigger beams into place. Very few were interested in renting out their expertise and machines for such small jobs.

QUESTIONS & ANSWERS

BUILDING MATERIALS

QUESTION:
I have been offered a municipal plot and will build a single-story house. One of the questions is whether we should build with Ytong or wood. What are the 5-10 most important advantages and disadvantages of each material choice?

ANSWER:
Exterior wall frames along with roof construction made of wood, prefabricated in a factory, are usually assembled in two days. In these elements, windows and doors with glass are installed. You then quickly get a moisture-tight building, which is very essential to prevent the onset of mold and rot. Exterior wall frames of wood can be clad with wood paneling, which is treated every 5-6 years. Alternatively, they can be clad with foam plastic insulation, provided with reinforced colored thin plaster of some kind. This latter type of insulated plaster is sensitive to impacts and bumps and is difficult to repair. The wood frame has quite poor heat capacity, meaning it cannot store heat. This may result in high indoor temperatures during an extended heat period in summer. The wood frame alternative offers relatively low production costs.

Exterior wall frames of lightweight concrete can also be assembled as elements in a few days. Roof trusses and exterior roofing are mounted in a few more days. Windows and doors are installed thereafter. Façade surfaces are coated with reinforced thick or thin plaster, which is colored with suitable paint. The longer assembly time for the lightweight concrete alternative is offset by its much greater tolerance for moisture. It can absorb moisture without the risk of rot and mold. The lightweight concrete frame also has good heat capacity, meaning it can store heat. You then get a cooler indoor climate during an extended heat period in summer. The lightweight concrete alternative offers slightly higher production costs than the wood alternative.

Together with Mrs. Lind's quote of 120,000kr for stone for a house of 280m2, it sounds like lightweight concrete is God's gift to the DIY builder!!!

But seriously, there must be some real disadvantages to lightweight concrete???
