Most standard loft conversions qualify as Permitted Development (no planning permission needed) if under 40m³ for terraced or 50m³ for semi-detached, with matching materials and 20cm eaves setback. However Hackney has Article 4 Directions that may remove these rights — and flats, conservation areas and listed buildings always require full planning. We confirm permitted development eligibility at the free feasibility visit.
Our architectural technology fees for a Hackney loft conversion start at £1,225 (planning + building regs + structural). Typical construction build-cost in Hackney is £45,000–£80,000 for a standard dormer and £65,000–£110,000 for a mansard.
Very often yes in Hackney. Rear mansards are routinely approved by Hackney Council where the design matches the terrace — including within conservation areas like De Beauvoir Town. A Heritage Statement and sensitive design following the borough's published guidance are essential for conservation area mansards.
2.3m measured from existing ceiling joist to existing ridge is the practical minimum for a standard conversion in Hackney. Below 2.2m usually requires dropping the ceiling below (reducing rooms on the floor beneath) or redesigning as a mansard.
Most Hackney loft conversions trigger Party Wall Act notices — legal notices to all adjoining owners. Rear dormers can also prompt right-to-light considerations in dense terraced streets, particularly in De Beauvoir Town. We handle both processes.
Hackney's victorian terraces dominate stock lends itself to rear dormers (most common), hip-to-gable (semi-detached), and mansard (period terraces and conservation contexts). Velux-only conversions are possible where ridge height allows. We recommend the best structural and planning route at survey.

Most Hackney loft conversions require Party Wall notices to adjoining neighbours — typically for steel beam installation and/or raising the party wall. We can co-ordinate the notice process; our in-house engineer handles the structural element. The Act gives neighbours 14 days to respond.
