Loft Conversion Specialists for Cardiff Homes
A loft conversion adds a proper room without losing an inch of garden, which matters in Cardiff where rear gardens on terraced streets are already tight. Greentek Energy Ltd starts every project with the three things that decide everything else: the headroom you have, where a staircase can go, and what the existing roof structure will take.
Which conversion suits a Cardiff roof
It depends entirely on the roof you've got. A Velux conversion is the simplest and cheapest where the headroom is already there. A dormer loft conversion builds out from the slope and adds both headroom and usable floor area, which is why it suits so many of Cardiff's terraces and semis. Hip-to-gable works on hipped roofs, common on inter-war semis in Llanishen and Whitchurch, and a mansard gives the most space but changes the roof the most.
Victorian terraces and the staircase question
In older Cardiff terraces the loft is usually workable, but the staircase is the puzzle. It has to meet building regulations for headroom and escape, and it takes space from the floor below, normally out of the smallest bedroom. We work out where it lands at the survey and show you what the first floor looks like afterwards, so there are no surprises once the work starts.
Planning and building control in Wales
Many loft conversions in Wales fall under permitted development, but the volume allowances and conditions are not identical to England's, and conservation areas around parts of the city tighten them further. Building regulations approval is always needed, covering structure, fire safety, escape routes, stairs and insulation. We confirm the planning route for your address and handle building control as part of the project.
Often done alongside a loft conversion in Cardiff
- Loft Insulation in Cardiff — the rest of the roof space insulated while access is easy
- Full Home Renovation in Cardiff — when the whole house is being brought up to standard
- Heating Upgrades in Cardiff — an extra floor means the system needs to cope with more rooms
Beyond the city, the same team builds loft conversions in Newport, Bridgend, Neath and Merthyr Tydfil. For the full detail on how these projects run anywhere in the UK, see our Loft Conversions page.
