Period Property Conversion Specialists
Conversion Engineers in Kensington & Chelsea
Converting Kensington's grand townhouses into flats, maisonettes, or mixed-use spaces requires structural engineering that respects heritage character while creating modern, functional layouts. We design steel frameworks, new floor structures, and load path modifications that satisfy both RBKC's conservation officers and Building Regulations.
Local Challenges
Conversions in Kensington & Chelsea
Period conversions in RBKC often involve listed buildings or properties within conservation areas. Structural interventions must demonstrate minimal impact on historic fabric — original cornicing, ceiling roses, and facade details must be preserved. Fire separation between new units requires careful structural detailing to achieve compliance without compromising heritage features.

Permissions & Approvals
What Approvals Do You Need?
Planning Permission
Change of use from single dwelling to multiple units requires planning permission in RBKC. The council assesses impact on housing stock, parking, and neighbourhood character.
Listed Building Consent
Internal structural changes to listed buildings require LBC demonstrating minimal intervention and reversibility where possible.
Building Regulations
Fire separation, sound insulation, means of escape, and structural stability must all comply with Building Regulations for multi-unit residential.
Licence to Alter
Leasehold properties require freeholder consent. Major estates (Cadogan, Wellcome) have their own structural review processes.
