FAQs

What kinds of loft conversion are there?

There’s a huge range of different types of loft conversions. The most common are dormer and skylight or Velux conversions. There are also hip to gable and mansard conversions. The type of loft conversion that’s most suitable for your property will depend on the style of roof and the size of your loft.

how much is a loft conversion?

With the ability to add approximately one third of your existing living space ( by converting your old, unused attic) to your home or property without having to let go of your garden, it’s quite easy to see the reason why loft conversion has rapidly grown to become one of the most popular home improvements in the UK. However some homeowners usually shy away from the idea simply by looking at the perceived high cost of carrying out such a project, despite several researches showing that loft conversions offers the best rate of return on initial investment when compared to the other home improvement projects. So exactly how much would it cost to carry out this project?

Just like several other home improvement projects, the cost of a loft conversion varies greatly depending on a wide range of influencing factors. These factors include the size of your home, how old your home is as well as the quality of the fixtures and fittings you want to install. For instance, a high end bathtub alone can cost you thousands of pounds, meanwhile you can also construct a full bathroom suite on just a couple of hundred pounds. However, to give you an idea of the minimum cost of a loft project we’ll look at the most popular types and the minimum cost of each.

✓ Internal Loft Conversion - The most affordable type of loft conversion tends to start from £25,000 and above.

✓ Dormer or L-Shaped Dormer Loft Conversion. These are the most popular types of loft conversion. Dormer price tends to start from £35,000, while the L-shaped dormer starts from £45,000.

✓ Mansard Loft Conversion - This involves replacing the entire side of a sloping roof with a vertical wall and flat roof. It requires a planning permission. The type of loft conversion usually starts from £45,000.

✓ Hip To Gable Loft Conversion - This usually starts from £50,000.

Can my loft be converted?

Many types of loft are suitable for a loft conversion. In general, you will need at least 2.3 metres of headroom in your existing loft. This is to make sure there is enough headroom after the conversion. Speak to a conversion specialist about the probability and possibility of doing this in your house.

how much value does a loft conversion add?

When its impossible to build out and create more space sideways, why can’t you look upwards? As more and more homeowners in the UK are carrying out their loft conversion project, one question that keeps popping up is the amount of value the loft conversion can add to their homes. However, this is a question that is impossible to provide a single and precise answer to. This is because the value that’ll be generated by a loft conversion is largely dependent on a wide range of influencing factors. To give you a vague idea of the loft conversion value to a property, we’ve put forward a research carried out by industry experts so you can know what you’re in for.

Nationwide carried out a research which shows clearly that a loft conversion including an additional bedroom as part of the building plan will increase a house’s value by up to 21 percent. Since the number of rooms a house has is one of the main metrics for house valuations, loft conversion comes in pretty handy as it’s a great and easy way to convert your house from a 4 bedroom house to a 5 bedroom house prior to sale.

Apart from the financial value aspect, loft conversion also adds more value to your lifestyle which is very unlike nearly other financial investments you can make. More space in your house automatically means more storage or a new room as you wish. A new room can be for a growing family or probably to serve as a guest room. It can also be used as a study space or even an office especially with the rapidly growing rate of people working from home. With loft conversion, the possibilities in terms of value are simply endless!
