ᐅ Using a Tiny House as an Extension or Affordable Extension Options?

Hello Homebuilding Forum,

After a long search, we found a house we'd like to buy because the plot has the perfect location for us, the house itself is really nice, and the price of about 500,000 EUR is also within our range.

Unfortunately, there is one point that doesn’t quite work for us yet: the house currently has a size of about 100 square meters (1,076 square feet) plus a converted attic of about 20 square meters (215 square feet). For us as a family, that feels a bit tight, and we would need about 2-3 additional rooms, roughly 50 square meters (538 square feet) more space.

Our first idea was an extension – and so we had quotes made. However, these amount to nearly 180,000 (plus additional costs) for 50 square meters (538 square feet), which is well over our budget.

Our next idea was to possibly connect a tiny house or similar through a conservatory to the main house to gain additional space. Our initial calculation shows costs of around 100,000, which would roughly be feasible for us. Is there anything we might have overlooked here?

Are there other options to gain more space? Are we missing something or do you know of providers who offer extensions in Lower Saxony at a lower cost?

I look forward to any input or suggestions.

Best regards

We are currently estimating around 50,000 EUR for a tiny house from Pineca – (self-build could probably save some money) – additionally, we would budget about 8,000 EUR for the concrete slab, and since we only need electricity there (bathroom in the main house), we are actually expecting a maximum of 2,000 EUR for that. For the remaining 40,000 EUR, we roughly plan to realize the connection to the conservatory.

Maybe you can tell us what kind of tiny house you have in mind. Pineca is actually a garden shed manufacturer, but they have nothing to do with tiny houses (although they do offer garden houses/wooden huts insulated up to KfW 40 standard).

We are currently budgeting around 50,000 EUR for a tiny house from Pineca – (building it ourselves could probably save some costs) – adding approximately 8,000 EUR for the foundation slab, and since we would only need electricity there (bathroom in the main house), we are estimating a maximum of 2,000 EUR for wiring. For the remaining 40,000 EUR, we are roughly planning to create the connection through the conservatory.

Are you aware that small details like flooring, roofing, gutters (and, of course, their connection) are still missing? 2,000 EUR for electrical connections is a very tight estimate, and I don’t see any heating system included for the annex yet. Also, even if the houses are labeled KfW40, there likely isn’t a finished approval as such or as living space compliant with energy-saving regulations (EnEV). So, an energy consultant will need to be involved.

We would like to use the additional space for a master bedroom plus 1-2 home office rooms.
Well, with that use, I would at least plan for a toilet, or better yet a full bathroom. Since the "tiny house" is intended for after the children move out, it might actually call for a more independent unit.

Also, the points made by the previous posters are important.

I have already seen some nice external solutions in the form of garden sheds or small bungalows. You can "go to work," which motivates and adds structure to working from home. You only need electricity, and it doesn’t have to be living space, so sometimes the square meters (square feet) inside the house are sufficient. Heating could be done with a small stove, and with a 1,250 m² (13,455 sq ft) garden, it can be nicely integrated.

It must be considered living space. Otherwise, the company could get into serious trouble, and the responsibility is often passed on to the employee. That’s how it was with me, for example.

But that’s not the case in every company.
For my husband, they specifically called it mobile work, not working from home, so that employees can work wherever they want.

Regardless, nobody really checks where you are actually working. Paper is patient.
