Trollhättan sells house plots through its plot queue. When a new area is released, queue members are informed and can rank the plots they want. Investigate each option before ranking: a plot near the city's river corridor and one farther out can have different plans, ground and water services. A queue place does not replace a building permit.Available plots
In Trollhättan's plan archive, adopted detailed plans are marked in red. Search by address, property or district and open the plan documents. The municipality cautions that rules shown directly in the map are an interpretation; the original plan map is legally binding. Ask for the documents if they are not yet in the archive.Plan archive

A new one- or two-family home in Trollhättan always needs a permit. The city requires a certified control manager named in the application. After the permit, a technical meeting normally reviews how the work will be carried out; you need a start notice before construction. Also ask whether the plot is affected by cultural heritage or shore protection.Build a new home

Trollhättan Energi runs public water and wastewater. Properties inside its service area have a right to connect, but you need the connection point and process for your exact plot. Contact the company early, especially if building outside the town centre. Outside the service area, investigate other water and wastewater options.Connect to water and wastewater

Trollhättan's map portal helps you explore the plot, plans and surroundings. For a new home, you normally need a new-build map, also called a permit map, as the base for the site plan. Ask the permit team which map is required, then draw in the home and its distances to boundaries before applying.Maps

The Göta river runs through Trollhättan, with falls and locks in the central Älvrummet outdoor area. The municipality also describes farmland and hillier ground beyond the centre. For a homebuyer, these mean different surroundings, journeys and land conditions. Visit the actual plot and compare daily routes, not only the view.Nature and parks
