Velux Loft Conversion
Velux loft conversion uses the existing space under your roof to transform it into a livable space with Velux roof windows. It does not require structural changes to the roof, saving you money and time.
Price: Starting from £35K
Domer Extension
A Dormer loft conversion involves constructing a box-shaped extension on a slanted roof, resulting in walls that form a right angle with the floor. This clever addition not only increases the available headspace but also expands the overall floor area.
Price: Starting from £50K
Double Mansard
A double Mansard loft conversion is the most spacious and extensive option available. This type of conversion involves constructing both a front and rear Mansard, adding an entire new storey to the property.
Price: Starting from £65K
L shaped Mansard
An L-shaped Mansard combines the Mansard roof design with an L-shaped floor plan. It consists of a horizontal section and a right-angled section on the adjacent side. An additional room sits over the rear outrigger.
Price: Starting from £70K
Hip to gable
A hip to gable loft conversion is well-suited for end of terrace and detached houses. This type of conversion involves altering the inwardly slanted end roof of the house to create a vertical wall. By doing so, the original hip roof is transformed into a gable roof.
Price: Starting from £65K
L-Shaped with full back addition
An L-shaped Mansard conversion involves the construction of two mansard builds that are interconnected. Typically, one Mansard is built on the rear outrigger roof, while the other is constructed on the main roof, resulting in the distinctive L-shape of this type of conversion. Price: Starting from £75K
Half L Shaped
It is a regular L-shaped dormer with a shorter rear end. The main roof gets extended fully, but the dormer on the outrigger does not extend across the entire rear roof.
Price: Starting from £65K
L Shaped with Balcony
It is a half-L-shaped conversion with a balcony for the rear dormer. The remaining roof structure left by the half-sized rear dormer gets converted for balcony space. The design offers a room with a view.
Price: Starting from £70K

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.
