FAQs

how disruptive is a loft conversion?

Asides the questions relating to planning permission of a loft conversion as well as the total cost of completing a loft conversion project, this is perhaps the most common question on the loft conversion subject matter. Before making an investment decision, many homeowners will want to know just how disruptive a loft conversion is. Well, we’ve all heard the several horror stories when loft conversion builder with dirty boots tramples all over the fresh and just-acquired shag pile or the noise of the construction loud enough to annoy neighbours from four blocks away or an obvious shortage of teabags, sugar and lots more. Good news is, the disruption of loft conversion is not as bad as people make out. Let’s have a look at how it works!

Just like all other major building projects, a loft conversion is disruptive to your property. However, no two loft conversions are the same, therefore some are certain to be more drastic and invasive than others. In the long run, the project is worth the stress and inconveniences caused and in most cases, it’s usually a very good investment.

Normally, an average loft conversion is expected to last for about 9 to 12 weeks (depending on the complexity of the loft conversion project some might take longer). Some of the factors that affects the duration of a project includes the type of the loft, the design of the loft as well as the style of the property.

Generally, a loft conversion is a lot less disruptive than say completely moving a home. It all has to do with how you’re able to deal with it as a person. And besides, the effect it’s going to have to a large extent depends on the company you hire. A good company will always look to ensure to keep disruptions to a minimal when carrying out the loft conversion project.

what is a hip to gable loft conversion?

This is a type of loft conversion that extends your roof on the sloping side. It is a great option to go for especially where a hipped roof effectively makes the usable floor area a lot smaller which can be a tricky affair when it comes to putting in a new staircase. Here, the roof is extended from the current ridge in such a way that it effectively fills the gap between them. As a result, this turns the hip (in a hipped roof) into a gable to create space in your roof for a loft conversion - hence the name “hip to gable.

The new gable can be done in whatever way that suits both your taste as well as your property. You can make the new gable construction in woods and then tiled to match your existing roof while you can also go for other options such as brick block pebbledash or rendering. You are also free to fit in a new window into the loft conversion end so as to allow for natural light into the loft space.

A hip to gable loft conversion is mostly found on both semi detached and end terrace buildings, particularly those constructed in the 1930s. Overall, this type of loft conversion is particularly ideal for homes that features a hipped roof and with a sloping roof at the side of the property. Some detached properties can also possess a hipped roof on the side - and as such, a double hip to gable loft conversion can also be deal as it’ll create more loft space for usage. If your home fits into the bill, then you should be aware that once the project is completed, you’ll have plenty of usable space available to both you and your loved ones.

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 long does a loft conversion take?

If you’re about to carry out a loft conversion project, you’d probably be wondering how long it’ll take to complete the task. Well, you’re not alone! This is one of the most common questions when it comes to loft conversion projects, however, providing a set timeframe for completion of such projects is impossible as all loft conversions vary. There are different factors that can determine the duration of your project. These factors include, the materials to be used, the type of the proposed loft conversion, the kind of staircase you’ll like to have installed, the number of windows included, the number of rooms to be added as well as a number of other influencing factors. As a result of these variables, the milestones and timings provided are only to be taken as guidelines. If you’d really like to have a set date, you can get in touch with a professional for help.

Generally, it’ll take up to 8 weeks to complete a loft conversion project.

✓ The first week activities will include putting up scaffolding, receiving the first materials for the build and creating an opening in the roof to gain access to the loft space.

✓ In the second week, the structure of the roof will be ammended and more support added.

✓ Third week, the floor joists will be fitted, building of the loft conversion will start, completion of the external roof works and commencement of plumbing and electric works.

✓ Fourth week, complete the building, construct the loft floor, fit the roof windows, insulation, ventilation and internal stud walls.

✓ Fifth week, apply plaster and plasterboard to the room walls, create a staircase opening and fit the new staircase.

✓ Sixth week, plaster the staircase area, complete plumbing and electrical works, hang the doors, fit skirting, handrails and bannisters and start decoration.

✓ Seventh week, complete the decoration and clean and wipe out all wastes.

✓ Eight week, complete all the remaining tasks.
