Loft Conversion — Fulham & South West London
A loft conversion is the most reliable way to add a bedroom to a Fulham terrace, and the most common reason one fails is a decision made before anyone measured the roof. These answers cover what to check first, what each conversion type gives you, and what typically goes wrong.
When can you not do a loft conversion?
The deciding factor is headroom: you need at least 2.2m from the top of the existing ceiling joists to the underside of the ridge. Below that, a standard conversion cannot retain the 2m of usable head height required once the new floor and insulation are installed.
Read the full answerIs it worth doing a loft conversion in London?
In most cases yes. A loft conversion adding a double bedroom and en-suite typically increases a property's value by 10 to 20 percent, and in Fulham — where price per square metre is high and moving costs are substantial — the uplift usually exceeds the build cost.

The most frequent problems are overheating from inadequate insulation and ventilation, a staircase that ruins the floor below, insufficient headroom at the top of the stairs, and missing building regulations sign-off. All four are design failures, and all four are avoidable.

A loft conversion adding a bedroom and bathroom typically increases a home's value by 10 to 20 percent. The uplift is largest where it takes the house from three bedrooms to four, because that moves it into a different bracket for buyers rather than simply adding floor space.
Read the full answerWhich loft conversion suits a Fulham Victorian terrace?
A rear dormer is the standard and usually the best choice for a Fulham terrace — it creates full-height space across the back slope, typically fits within permitted development, and costs £55,000 to £85,000. Where headroom is marginal or the house is in a conservation area, a mansard may be the only option.

A dormer adds a flat-roofed box projecting from an existing roof slope. A mansard rebuilds the roof at a near-vertical angle for maximum space. A hip-to-gable squares off a sloping side roof on an end-terrace or semi. Cost rises in that order, as does the likelihood of needing planning permission.

Ten to fourteen weeks on site for a rear dormer, or fourteen to twenty for a mansard. Before that, allow eight to twelve weeks for design, structural calculations and either a planning decision or a lawful development certificate, plus two months for party wall notices.
Read the full answerDo I need building regulations approval for a loft conversion?
Always, without exception. A loft conversion is structural work and must satisfy building regulations for floor structure, staircase design, fire escape, insulation and ventilation. The process ends with a completion certificate, which is the document a buyer's solicitor will ask for.
