Calculators for garden and construction

Our garden and construction calculators help you calculate the right amount of materials for your project. Whether you're landscaping a new garden, building a terrace or renovating your house, you can save time and money by calculating exactly what you need.

Garden

Calculate the amount of grass seed, fertiliser, bark mulch, soil and gravel for your garden. Plan your hedge with the right plant spacing and calculate how much turf you need. Denmark has approximately 1.5 million detached houses with gardens.

Construction

Calculate the amount of paint, wallpaper, tiles, concrete, cement, sand and other building materials. From bricks and insulation to flooring and laminate, our construction calculators help you plan your project precisely. Always calculate 5-10% extra for waste.

Asbestos

Calculate the cost of removing and disposing of asbestos roofing. In Denmark, asbestos must be handled by certified companies and reported to the municipality. Typical prices for asbestos roof removal range from 150-350 DKK per m². Asbestos roof sheets were banned in Denmark in 1988.

Construction price increases

Construction prices in Denmark have risen significantly in recent years. Calculate whether it pays to build now or wait, based on current price increases in the construction industry.

Frequently Asked Questions

How much grass seed do I need per m²?

For new seeding, 25-35 grams of grass seed per m² is typically recommended. For overseeding thin patches, 15-20 grams per m² is sufficient. The amount depends on the grass type – fine lawn grass typically requires more seed than coarser types. Best sown in spring (April-May) or late summer (August-September).

How much concrete do I need per m²?

Concrete consumption depends on the thickness. At 10 cm thickness, you need 0.1 m³ of concrete per m², equivalent to about 240 kg. A standard 20 m² terrace with 10 cm thickness therefore requires about 2 m³ of concrete (about 4,800 kg). Remember to calculate 5-10% extra for waste.

How much does it cost to remove an asbestos roof?

The cost of asbestos roof removal in Denmark typically ranges from 150-350 DKK per m². For an average detached house with approximately 120 m² of roof, that means about 18,000-42,000 DKK for the removal itself. The cost of a new roof, typically 800-1,500 DKK per m², is additional. Remember that asbestos must always be removed by a certified company and reported to the municipality.
