Velux loft conversion drawings in the City of London

The Barbican and listed estates

Much of the City's housing sits on a handful of estates, the Barbican among them. The council's guidance for it is the Barbican Estate Listed Building Management Guidelines: Volume I Introduction and Volume II Residential (SPD), which governs changes to flats in a listed estate. A rooflight on a listed building is a listed building matter, not a householder one, and the consent route is separate from the work on this page.

We tell clients this early because it changes the cost and the timescale. A rooflight project that might be a simple certificate in a suburban street becomes a heritage application in the Square Mile, and the drawings need a statement to match.

Across the City, the records also show 1 Article 4 direction and 5 entries on the Heritage at Risk Register. Both are reasons to check the address before anything else.

What the planning figures can and cannot tell you

Most planning statistics are meaningless at this scale. In its latest year the City decided 1 householder application. With a sample of one, the grant rate of 100 per cent and the in-time rate of 100 per cent say nothing about the next application, and we do not use them to predict anything.

A better guide is the certificate record. The City dealt with 16 certificate applications of all kinds in its latest return, which suggests that some owners do confirm lawful work this way. Where the address and the roof allow it, a lawful development certificate is still the route we look at first for a rooflight scheme.

The wider policy framework is the City of London Local Plan 2015, adopted in 2,015. We check which document the officer will use when your application is decided.

Flats, leases and whose roof it is

For a flat, the legal position matters as much as the planning one. Rooflights usually change the roof, and the roof usually belongs to the freeholder. Without the freeholder's written consent, a council decision does not give you the right to cut into the roof, and the lease may forbid it. We ask for the lease or title at the beginning, and we give you a short note to take to the managing agent.

Average prices are high: the average home in the City sold for £710,652 in the latest figures, and only 36.5 per cent of households own their home. Many residents rent, and many owners hold a lease with strict conditions. That is why we treat consent as part of the design process and not as an afterthought.

Building regulations still apply

Even when planning is simple, a loft room has to meet the regulations, and these do not vary by borough. Any new habitable room needs an alarm system at the standard the guidance sets: All dwellings: fire detection and alarm system minimum Grade D2 Category LD3 (BS 5839-6), mains-operated smoke alarms to BS EN 14604. We show the alarms and the escape window on the plans, and we draw the stair so that its headroom and fire protection are clear.

City of London building control, or a registered building control approver, will want that information at the start. We prepare the drawings in the form they expect and flag where a fire engineer may need to advise, for example in a building with a shared stair.
