Loft Conversions
Turn unused roof space into the best room in the house.
We design and build dormer, hip-to-gable, mansard and Velux loft conversions across Kent and South East London — from Victorian terraces to 1930s semis.
More space, without extending into the garden.
A loft conversion is usually the most cost-effective way to add a serious amount of space — typically a master bedroom with en-suite, two kids' rooms, or a home office and snug. Crucially, you keep your garden intact and you don't need to sacrifice ground-floor light.
We've converted lofts on every common roof type in the area: cut roofs, trussed roofs, hip ends, gable ends, and the awkward shallow pitches that come with some inter-war semis. The right conversion type depends on your roof, your headroom, and what your neighbours have been allowed to do — we'll walk through it all at the site visit.
Most of our loft conversions are completed without you needing to move out. We work primarily through the existing scaffolding and roof access for the structural phase, then tidy up internally during second fix.

In their words
“Irinel and his team were amazing. Done a really good job with my extension. They were very polite and professional. No matter what you asked he was more than happy to accommodate and give advice on what works best. Definitely recommend and will be using again should I have future jobs.”

FAQ
Common questions
- Do I need planning permission for a loft conversion?
- Most loft conversions in Kent and South East London fall under permitted development, but there are exceptions — conservation areas, double-storey homes with restrictions, and anything that exceeds the volume allowance. We check at the free site visit.
- Will my ceilings be high enough?
- We need at least 2.2m of clear height in the highest part of the loft to make a comfortable conversion. We measure properly at the site visit and tell you straight away if it'll work.
- How long does it take?
- A typical dormer loft conversion runs 8–12 weeks on site. Hip-to-gable and mansard conversions tend to be 10–14 weeks. You'll have a written schedule with the quote.
- Can I stay in the house during the build?
- Yes — almost all our loft conversions are done with the family in residence. We work primarily from the scaffolding for the structural phase to keep dust and disruption downstairs to a minimum.
- What about the party wall?
- If you're in a terrace or semi we'll handle the party wall notice process for you — it's a legal requirement and we make sure it's done properly so there are no disputes later.
