Loft Conversions
Unlock extra space with a loft conversion.
Constructum Code is a specialist loft conversion company in London, with loft conversions at the core of our expertise and a major part of our projects.
Benefits of Loft Conversions
A loft conversion is a practical way to create extra living space and increase the value of your property. It transforms unused attic space into bright, functional rooms such as home offices, bedrooms or studios. For many homeowners, it is a cost-effective alternative to moving, often making use of the existing framework and avoiding major structural changes.
Styles of Loft Conversions
Among the most popular options are dormer loft conversions, which extend the roofline and add windows to maximise natural light and ventilation. We also offer mansard, hip-to-gable and Velux loft conversions, along with bespoke designs tailored to each property and client.
Loft Conversion Costs
Each style has its own advantages, and costs vary depending on the type of conversion, the size and shape of the attic, and the finishes you choose:
Project Type — Smaller Velux conversions are budget-friendly, while larger designs such as a modern dormer loft conversion or mansard extension provide additional space and light.
Attic Size & Shape — Larger or irregular lofts may increase costs but offer greater flexibility in design.
Materials & Finishes — Premium options add to costs, while standard choices keep budgets manageable and still deliver a high-quality finish.
Planning Considerations
To ensure every loft conversion is practical, comfortable and compliant, we guide clients through the essentials:
Design & Style — The new space should complement your home’s architecture.
Ceiling Height — Dormers can provide additional headroom where space is limited.
Space Planning — Careful layouts maximise comfort, storage and practicality.
Accessibility — Safe, well-designed staircases connect the loft to the rest of the house.
Storage — Built-in cupboards and shelving improve functionality.
Natural Light — Skylights and windows enhance comfort and energy efficiency.
Insulation — Essential for year-round comfort and reduced energy costs.
