ST Lofts has been transforming homes Across Bristol for Years.

If you’re a Bristol homeowner looking to create more space without the cost and upheaval of moving, a loft conversion could be the smartest decision you make this year. 

At ST Lofts, we specialise in transforming underused roof space into beautiful, functional rooms  and we’ve been doing it across Bristol and the surrounding area for years.

Whether you want an extra bedroom for a growing family, a quiet home office away from the rest of the house, or a space that’s entirely your own, a professionally converted loft delivers exactly that  and adds serious value to your property at the same time.

Do Bristol Properties Need Planning Permission?

Many loft conversions in Bristol fall under permitted development, meaning no planning application is needed. However, if your home is in a conservation area (Bristol has several, including Clifton, Redland, and parts of Southville) then different rules may apply. 

Our team will advise you clearly after assessing your specific property.

Frequently Asked Questions.

For answers to the most common questions about Bristol loft conversions, visit our Bristol Loft Conversion FAQ page.

Not sure which type of conversion is right for you? Our loft conversion glossary explains every term in plain English.

We also carry out loft conversions in Bath, Somerset, Gloucester, Swindon and Weston-super-Mare.

Most loft conversions take between six and ten weeks from start to finish, depending on the type of conversion and the size of your roof space. A straightforward Velux conversion will be at the quicker end of that range; a full mansard or hip-to-gable project may take a little longer. We’ll give you a realistic timeframe as part of your free survey.

In the vast majority of cases, no. Most of the structural work takes place at roof level, and our team works carefully to minimise disruption to the rest of your home. You’ll be able to carry on living in your house throughout the project.
As a general rule, you need at least 2.2 metres of headroom from the floor joist to the ridge of your roof for a loft conversion to be feasible. We’ll measure your roof space accurately during the free survey and tell you exactly what’s achievable.
Costs vary depending on the type of conversion, the size of your roof space, and your specification. We believe in transparent, honest pricing — which is why we always provide a full, itemised quote after surveying your property rather than giving vague estimates upfront.
