Storage loft cost: what do you pay for a storage loft?

What items make up storage loft cost?

A storage loft is a floor in the ridge of the roof, above the attic, intended for storage. The costs consist of a few fixed parts. The biggest difference lies in whether the existing joists can carry the floor and your belongings.

• Floor panels on the joists: roughly €40 to €90 per m²
• Hatch in the attic ceiling, or enlarging an existing one
• Loft ladder including fitting: often €500 to €1,200
• Lighting and a socket
• Extra joists or strengthening if needed

When does a storage loft cost more?

The price rises mainly when the structure needs adjusting. If the joists are too far apart or too light, joists are added or a new supporting structure is built. A hatch in an awkward spot, where a joist has to be cut and supported, also means extra work.

Insulation is a second factor. If the loft is in an unheated part, you often insulate the roof slope or the floor below. That prevents condensation on your belongings and heat loss from the attic. See insulating an attic for the options.

How does a storage loft compare with other storage?

A storage loft is often the most affordable way to create storage without giving up floor space downstairs. A garden shed or built-in cupboards under the slope of the attic generally cost more per m² of storage. On top of that, the attic itself is freed up for a room. That is why a storage loft is often combined with a larger conversion; see attic conversion cost.

What does a storage loft look like in practice?

For the Sloots family in Heerhugowaard, we created a storage loft and two rooms in the attic below. The loft is reached through a hatch, so the rooms remained free for sleeping and a hobby. See the project at storage loft Heerhugowaard.
