LOFT CONVERSION FEASIBILITY
Attic Headroom Audits, Stairway Geometry & Dormer Lines
Orama measures ridge-to-joist heights, staircase pitch angles, roof load distribution, and dormer insulation U-values with 45+ years of master building experience. We audit attic plans before timber framing begins to guarantee full headroom compliance and structural integrity.
COMMON QUESTIONS
Loft Conversion FAQs
Clear answers on ridge height requirements, dormer construction, staircase regulations, and party walls.
It depends on what your property is missing. A loft conversion is usually the ideal solution when you need another bedroom, master suite, or home office, because it uses the existing roof footprint without taking up garden space. A rear extension is more appropriate when the problem is downstairs, such as a cramped kitchen, poor layout, or dark dining area. Costas assesses your home's layout during the initial site visit to explain which option makes the best spatial and practical sense.
A ridge height of around 2.2m from the underside of the ridge timber to the top of existing ceiling joists is a useful baseline, but headroom suitability depends on roof pitch, structural floor joist depth, and staircase position. If ridge height is tight, structural steel placement and ceiling joist doubling must be calculated accurately so you don't lose valuable standing head clearance.
Loft conversions generally create less daily disruption inside the main house during the early weeks because scaffolding is erected externally and materials enter through the roof. Disruption becomes intense only for a short period when the roof envelope is opened and the new internal staircase is cut through. In contrast, a ground-floor extension disrupts the garden and primary living areas throughout excavation and structural steel installation.
Most rear dormer conversions fall under Permitted Development rights (up to 40 cubic metres of volume for terraced properties, or 50 cubic metres for semi-detached and detached homes), provided design guidelines are respected. Properties in Conservation Areas or subject to Article 4 Directions will require formal planning permission, which we verify prior to commencing work.
A typical dormer loft conversion takes between 8 and 12 weeks from scaffolding erection through structural steel installation, dormer framing, slate/zinc cladding, plastering, ensuite plumbing, and final Building Control sign-off.
Key cost factors include the conversion typology (rear dormer, hip-to-gable, mansard, or rooflight-only), structural steel sizes and crane/hoisting requirements, staircase reconfiguration to preserve lower-floor space, whether an ensuite bathroom is added, and exterior cladding choices (such as zinc, slate, or composite tiles). We provide a precise, transparent breakdown following an on-site headroom and roof survey.
