‍What Style is Right for Me?

The best type of conversion for you will depend on various factors including your property type and the space you want to create.

Types of Loft Conversions

Formed in 1986, Econoloft has experience constructing all styles of attic conversions for new and older houses, bungalows, flats and maisonettes across the UK. No matter what type we are working on, or your reasons for building a conversion, we provide a full in-house service that includes planning, design and construction management. We ensure your loft conversion suits your current needs and is flexible enough to change with you as your lifestyle or family changes.



Our most popular type of roof loft conversion is the Dormer loft conversion, which is suitable for most house types throughout the UK. This conversion entails a straightforward extension of your loft, resulting in a flat roof that extends from your sloped roof. This creates additional floorspace and headroom, turning your loft into usable living space.

If you have ample headroom in your loft, consider a Velux conversion, also known as a rooflight conversion. With our expertise as a Velux approved installer, Econoloft guarantees the highest standard of service when installing rooflights into your existing roof. This style of conversion requires no alterations to the roof structure, resulting in minimal disruption and making it one of the simplest and most cost-effective options available. Additionally, rooflight loft conversions often fall under permitted development, making them an excellent choice for homes with strict planning restrictions. Whether you reside in Orpington, Sevenoaks, St Albans, Sutton, Wandsworth, or anywhere else in the UK, this type of conversion is a fantastic solution.

Mansard attic conversions extend the slope of the roof until there is a near vertical drop, maximising space. While they tend to require planning permission, the internal space you gain makes the extra work worth it and Econoloft will guide you through the planning process, making it as easy and stress free as possible.

We customise mansard conversions to blend in with the architectural style of your home, making them perfect for all kinds of properties. They are especially popular in urban areas or sometimes conservation areas.

Hip-to-gable loft extensions are a favourite for semi-detached homes, and they replace the sloping side of hipped roofs with a vertical wall. This provides valuable extra space which ensures you can use your conversion the way you want. In addition, if you have a detached property with two sloping sides, we can even construct a double hip-to-gable conversion.

What to Expect


After consultations, home visits and planning services from our loft conversion specialists, we start building your loft extension. The exact process and services will depend on the specifics of your project, but general building work includes:


  • Appointing a foreman who is responsible for the smooth running of attic conversions and is your main point of contact.

  • Supply of high-quality materials, including Velux windows and blinds, Kingspan insulation, Celotex insulation and Saniflo systems.

  • Completing work within agreed schedules and budgets – as a customer focused loft conversion company, we agree realistic timeframes and budgets at the planning stage.

  • Ad hoc site visits from Econoloft supervisors to ensure work meets our standards.

  • Building control inspections to ensure work complies with regulations.

  • Erection of scaffolding for safe and easy access to your loft, minimising disruption to your home.

  • Thorough health and safety plans and measures

  • Construction of dormer, mansard and hip-to-gable loft conversions.

  • Installation of rooflights – our loft conversion specialists are approved Velux installers.

  • All necessary structural work including reinforcing the floor.

  • Roofing work, including EPDM flat roofs and cold roof construction.

  • Fitting insulation.

  • Wiring, plumbing and heating work.

  • Construction of staircases for attic conversions.


As a dedicated loft conversion company, we are experts in all areas of loft extensions. This includes current building regulations and planning requirements. As such, we make sure your project in Bromley is safe, functional and fully compliant.

Remember, Econoloft doesn’t just implement conversion designs; we provide a full loft conversion planning service prior to construction which includes producing quality hand-drawn designs. We are also experienced steel suppliers, ensuring the best and correct size steels for your project.



Econoloft completes loft conversions to a plaster skim finish. The foreman then goes through a snagging inspection with you to ensure you are happy that we have completed the agreed work. Building control inspectors also carry out a last inspection to give final approval and confirm that the conversion meets regulations, after which they give you a completion certificate.

In addition, Econoloft will provide you with our own completion certificate and a 10-year guarantee. Following construction, you are free to decorate and furnish as you wish.
