Frequently Asked Questions

In most cases, loft conversions fall under 'Permitted Development' and do not require full planning permission. However, if your property is in a conservation area, is a listed building, or if you are significantly altering the roof height (like a Mansard conversion), full loft conversion planning permission Cardiff may be required. We handle all planning checks, architectural drawings, and local authority submissions on your behalf. You can verify general guidelines on the official UK Planning Portal.

If your home is semi-detached or terraced, you share a wall with your neighbours. Under the Party Wall Act 1996, you must notify them if your loft conversion involves structural work on this shared wall (such as inserting steel beams). Yes, you will likely need an agreement, but we guide you through the exact notification process to keep things friendly and legally sound.

Yes, absolutely. Unlike planning permission, all loft conversions require Building Regulations approval to ensure they are structurally safe, fire-resistant, and properly insulated. Our in-house structural engineers prepare all calculations, and we liaise directly with building control inspectors throughout the build until you receive your final certification.

When budgeting for your loft conversion cost Cardiff, prices vary significantly based on the size of your property and the type of conversion. A simple Velux (roof light) conversion is the most cost-effective. Adding dormer windows, or undertaking a complex Hip-to-Gable or Mansard conversion, will require more structural work and a higher budget. The best way to get an accurate figure is to book a free feasibility survey with our team.

Yes. Nationwide research consistently shows that a well-designed, professionally built loft conversion (especially one adding a master bedroom and en-suite) can increase a property's value by up to 20%. It is widely considered one of the most profitable home improvements you can make, often adding more value than the cost of the build itself.

As a general rule, you need a minimum of 2.2 meters of clearance from the top of your existing floor joists to the highest point of the roof apex. If your loft is lower than this, a standard conversion may not be possible. However, we specialize in complex solutions, such as lowering the ceilings on the floor below or physically raising your roof (subject to strict planning approval).

A standard Velux or small rear dormer conversion usually takes around 6 to 8 weeks from the moment scaffolding goes up. Larger projects, such as hip-to-gable extensions or full mansard conversions, typically take 8 to 10 weeks. Because our team handles everything in-house, we rarely experience the delays associated with outsourcing sub-contractors.

Not at all. We design our process to be as non-intrusive as possible. For the first few weeks, all work is conducted via external scaffolding through the roof. We only break through into your main living space towards the end of the project to install the staircase. Your home will remain secure and fully habitable throughout the entire journey.

Building work inherently creates dust, but we take extreme care of your home. Heavy-duty protective coverings are laid down on your floors and stairs before any internal work begins. Our teams clean up at the end of every single working day, ensuring dust and disruption are kept to an absolute minimum.
