With space at a premium and property prices at historic highs, homeowners in London are increasingly seeking ways to maximise the value and functionality of their existing properties. One of the most practical and cost-effective solutions is a loft conversion—an innovative way to transform unused attic space into a fully functional living area.

At Crest Projects, we specialise in delivering tailored, high-quality loft conversion in London for a wide range of property types. Whether you own a Victorian terrace, a modern townhouse, or a semi-detached family home, our comprehensive design-and-build services ensure that your loft transformation is completed with precision, compliance, and lasting value.

Why Loft Conversions Are Ideal for London Homes

Space limitations are a common challenge for homeowners across the capital. With limited options to expand outward, converting the roof space offers a highly effective method of increasing living space without compromising garden or outdoor areas.

A professionally completed loft conversion not only adds functional square footage but can also increase your property’s market value by up to 20%, making it an excellent investment. Additionally, many loft conversions fall under permitted development rights, reducing the need for lengthy planning applications.

Types of Loft Conversions Offered by Crest Projects

Every home is unique, which is why Crest Projects offers a wide variety of loft conversion types to suit different property styles and homeowner requirements. Our team will conduct a detailed site survey and recommend the most suitable option.

1. Dormer Loft Conversion

This is the most common loft conversion type in London. A dormer creates a vertical extension from the roof, offering increased headroom and floor space. Ideal for adding a spacious bedroom or a home office.

2. Mansard Loft Conversion

A mansard conversion involves altering the entire slope of the roof to create a near-vertical rear wall. Often seen in Central London and conservation areas, this style offers the maximum additional space but usually requires full planning permission.

3. Hip-to-Gable Loft Conversion

This style is suitable for semi-detached and end-of-terrace properties. It involves extending the sloping “hip” side of the roof to form a vertical “gable” wall, which creates a larger and more usable loft area.

4. Velux (Rooflight) Conversion

This is a simpler and more budget-friendly option that involves adding skylights to an existing roof without altering the structure. Best suited to lofts with good existing height.

Our Process: A Complete Design and Build Solution

At Crest Projects, we provide a fully managed loft conversion service, ensuring a smooth, stress-free experience from start to finish. Our process includes:

● Initial Consultation

We begin with a complimentary consultation to assess the loft space, discuss the client’s goals, and determine feasibility. This stage includes measuring dimensions and identifying structural considerations.

● Architectural Design and Planning

Our in-house architectural team prepares detailed floorplans and 3D visualisations. We also handle all planning applications, permitted development certificates, and building regulation submissions to ensure full compliance.

● Structural Engineering

Our structural engineers ensure all conversions meet the latest safety standards and UK building regulations. This includes steel beam calculations, load assessments, and fire safety planning.

● Construction

Our skilled construction team carries out all necessary building works with precision and care. We ensure minimal disruption to daily life and provide regular progress updates throughout the build.

● Interior Fit-Out

Once structural work is complete, we undertake interior finishing, including insulation, electrical and plumbing installations, plastering, flooring, decorating, and staircase installation.
