Loft Conversions Lambeth

Velux (Rooflight) Loft Conversions – simple and cost-effective, it involves turning your loft into a livable space with the help of roof windows, usually Velux windows. No structural changes to the roof take place apart from that. Roof windows bring natural light and ventilation to the room. This conversion is ideal if your loft has enough head height.

Dormer Loft Conversions – A dormer conversion adds vertical space and headroom to a roof, with options for flat, hipped, or pitched roofs and dormer windows to create more usable space. They often get added to the rear and side. 

L-shaped Loft Conversions – ideal for Victorian semi-detached or terraced properties with a rear outrigger, the design incorporates two dormers connected at a right angle. One dormer sits on the main roof of the property, while the other is on the outrigger. This design works well with the shape of the outrigger and creates two separate living spaces, such as two bedrooms or a bedroom with an en suite.

Mansard Loft Conversions – French Baroque by origin, Mansards maximise head height and floor area for open-plan or multiple rooms. They have a steep roof with a flat or gently sloping top and an inward-sloping 72° wall. An entire plane of the roof gets converted, requiring substantial alterations. A double Mansard takes the form of a separate floor. 

Hip-to-Gable Loft Conversions – replacing the hip end with a gable end forms a hip-to-gable conversion. A double hip-to-gable conversion is feasible for a detached home. This design is particularly suitable for 1930s end-of-terrace and semi-detached houses with hipped roofs that restrict attic space.

A well-executed loft conversion with a clever design can yield a considerable return on investment. The total cost will differ depending on the type of conversion you select, the amount of floor area getting converted, any added features, and design components.

High-quality loft conversions enhance living spaces and property values. Anything poorly executed does the opposite. Professional space-maximising designs tailored to your home and needs are a key component. A loft conversion company with in-house architects can create bespoke plans centred on the available space, budget, preferences, and lifestyle. 

Plans should comply with building regulations and planning permission guidelines. Attempting a DIY project without this knowledge can lead to lawsuits and demolitions. The right design and expertise can add significant value and functionality to your home. It also saves you precious money, time, and effort.
