A loft conversion involves transforming the attic space of a home into a functional and livable area. Executed without sacrificing valuable garden space, it doesn’t involve expanding the property’s footprint. There are different types of loft conversions, some more suitable for certain properties and others suitable for all property types. When carried out to high standards, they can improve the resale value of a property. They are a more economical solution to a growing family’s needs or changing lifestyles. You can add a bedroom, an en suite, a bathroom, a home office, a podcast space, a library, a gaming room, or a yoga studio. Converting your loft also ensures it is well-insulated for better energy efficiency. Redundant loft spaces often lack insulation, leading to high energy bills due to heat waste through the roof.

Velux Loft Conversion – only suitable for lofts with adequate head height, it adds roof windows to your existing attic space to make it habitable. It doesn’t usually require planning permission, but hiring a loft conversion specialist will ensure the work complies with local building regulations and is feasible for your specific property.

Dormer Loft Conversion – one of the most common loft conversion types, it extends the roof vertically from the existing roof slope to create a box-shaped structure. Typically located at the rear of the property, dormers offer a functional floor area and headroom. It has dormer windows to bring in natural light and enhance the overall appearance.

Hip-to-Gable Loft Conversion – ideal for 1930s hipped roof semi-detached and terraced properties, it involves replacing the hip of the roof with a gable wall to create more head height and usable floor space in the loft.

Mansard Loft Conversion – French Baroque by origin, Mansard extends a whole roof plan to create a large open-plan living area or multiple rooms, replacing the sloping face of the roof with a near-vertical wall at the rear of the property. A double mansard seamlessly integrates with the rest of the architecture to appear like a separate floor.

L-shaped Conversion – two dormers join to form an L-shape. The larger dormer is usually placed perpendicular to the roofline, while the smaller dormer is built at an angle, creating the L-shape configuration. The design complements Victorian terraced or semi-detached houses that have rear outriggers.

The loft conversion cost is influenced by the type of conversion you choose, the size of the floor area created, complexities of structural changes, and design features. Options for conversion styles depend on the type of property, available loft space, and your requirements.

Room in the roof conversion (basic) –  £35,000

Dormer loft extension – £50,000

Mansard extension – £60,000 – £65,000

Hip-to-gable extension – £65,000

L-shaped extension – £65,000 – £75,000

How we deliver projects

Our process is simple and divided into two distinct phases with separate contracts: Design and Build. As a client you only commit to one phase at a time depending on what stage of the process you are in. Each phase consists of three stages as described below.

1. Design

This is the kick-off point for your project. We carry out a complete architectural measured survey of the property. This allows us to create accurate CAD design drawings. This is followed by a design meeting to start discussing your ideas in more detail.

2. Planning

At this stage we finalise the designs with you and start preparing planning applications as needed. We place a high priority on ensuring that plans, designs and schedules are all based on a thorough and detailed understanding of planning guidelines. We co-ordinate with local authorities until the decision is made, and the planning approval is secured.

3. Technical

Once the planning consent is secured, we translate the design drawings into more detailed technical drawings for the purposes of building control and construction. This also includes specifications and structural calculations. At this stage, we will also submit to you our ‘no obligation’ quote for the build phase.

4. Pre-build

90% of our clients decide to stick with us after the design phase is completed. Once the build contract is signed, we kick off the process by making sure all the pre-build processes are complete. These include assistance with party wall agreements, Thames Water build over agreement, submitting building control application, and preparing method statements etc as needed. This stage ends with a pre-start meeting with your foreman before the actual build begins.

5. Build

One of our foremen will be dedicated to your project and will be on-site to manage everyday works. Our project managers will be overseeing the works to make sure they are completed to high standards, within your budget and on time. Throughout the process we will keep you updated with the progress and coordinate the works with third parties such as kitchen or flooring suppliers. We will also advise and guide you to choose any suppliers if needed.

6. Handover

As the build draws to finish, we will help to iron out any ‘snags’ to make sure everything is completed to your satisfaction. We will put together all necessary certificates such as gas, electricity and building control completion along with warranties for glazing, boiler etc. At the final completion meeting, we will hand you these documents, together with the keys to your house. Needless to say, you can contact us any time after this, if you want us to look at something.
