Hello,

by default, our general contractor builds with a knee wall of 62.5cm (25 inches) for a 45° gable roof.

Increasing it by one masonry unit to 75cm (30 inches) results in additional costs of €1,600.

Do you think the extra cost is justified by the additional usable space?

Hello,

I would personally invest the EUR 1,600.00 to secure the maximum possible interior space for you.

The EUR 1,600.00 due now is nothing compared to the costs you might face in the future if you ever need to remodel because of this.

Furthermore, I see greater ceiling height and less space below the 2m (6.6 feet) line as a clear comfort advantage.

In our case, we also made full use of the maximum possible with a knee wall height of 140 cm (55 inches).

Regards,

Dirk

Hmm, from 62.5cm (25 inches) to 75cm (30 inches)...
I’m not sure if that will make a big difference. The 2-meter (6 ft 7 in) line shifts by exactly those 12.5cm (5 inches) on a 45-degree roof.
This really depends on the floor plan: if the rooms are large enough in terms of area, another option would be to raise the knee wall by installing built-ins under the slope (shelves, fitted wardrobes) and use the non-walkable space for storage.
In the bedroom, built-in wardrobes under the slope work well, while in children’s rooms, bookshelves or recesses for clothes are good uses. Storage space is also needed in the bathroom. This way, fewer dressers and shelves are needed for furnishings.

Best regards, Yvonne

I would do it. Those 10cm (4 inches) make a big difference in terms of feeling. We lived in an attic apartment with 75cm (30 inches) and once with 85cm (33 inches)... it definitely felt like a big difference!

Honestly? I would skip it. Why? Because in my opinion, anything under 1m (finished floor level) is not worthwhile. Add two more blocks and reduce the roof pitch, then at least you can place furniture. It will already be difficult if you want to put a dresser in. Most dressers are between 80 and 110cm (31 and 43 inches) tall. Therefore, I definitely wouldn’t build a knee wall under 1m.

As previously mentioned, the maximum eaves height is 4m (13 feet), otherwise we would set the knee wall to 1m (3 feet). A shallower roof pitch won’t help us in this case either...

Can’t you gain a few more centimeters? For example, by lowering the foundation slab a bit (usually there’s a step from the street up to the house), or by reducing the ceiling height on the ground floor by a few centimeters (depending on the design). If that’s not possible, then keep the 62 cm (25 inches) and create an interior knee wall to use as storage space. You can store a lot in there. In our old bathroom, we built in a closet there, and in the current attic it’s used for suitcases and the kids’ toy boxes.

What is your roof pitch?
