A loft conversion refers to the process of converting the often empty attic in a home into usable space. It aims to maximise the available space within a property and create additional rooms or living areas. There are several designs and layouts to choose from based on the property type, local building regulations, homeowner’s preference, and budget. Most conversion types are suitable for all property types. When carried out professionally to visually appealing designs, loft conversions can improve property value. They are the preferred solution when you want to upsize without moving.

Velux Loft Conversion – known also as roof light conversion, it only involves the addition of roof windows to the existing roof slope of the attic space. While roof light conversions generally do not require planning permission, they need a professional architect or loft conversion specialist to ensure compliance with local building regulations and to assess the feasibility of the conversion based on the specific property and its roof structure.

Dormer Loft Conversion – this box-shaped addition is one of the most common types of loft conversion for creating space on a modest budget. It is a box-shaped structure that protrudes vertically from the existing roof slope, often at the rear of the property. Dormers offer functional floor area and headroom. They also feature dormer windows to bring in natural light and enhance the aesthetics of the conversion.

Hip-to-Gable Loft Conversion – ideal for the 1930s hipped roof semi-detached and terraced properties, this conversion turns the sloping side of a hipped roof into a vertical gable wall to create more headroom. It maximises the usable floor space in the loft and adequate head height for the staircase.

Mansard Loft Conversion – it extends a whole roof plane to create more headroom and floor space for multiple rooms or a large open-plan living area. Built at the rear of the property, it replaces the entire sloping face of the roof with a near-vertical wall. A double mansard can create a space that seamlessly integrates into the rest of the architecture to appear like a separate floor.

L-shaped Conversion – It is two dormers joined to form an L-shape when viewed from above. The dormers are typically constructed at the rear of the property, extending from the main roof slope. The larger dormer is usually placed perpendicular to the roofline, while the smaller dormer is built at an angle, creating the L-shape configuration.

Loft conversions are space-maximising and value-optimising solutions. The cost of your loft conversion in Wimbledon depends on several factors, from the size of your property to the nature of your requirements. Bespoke solutions can effectively trim costs while offering clever designs for your home’s architecture. Here is a basic cost breakdown for loft conversions in Wimbledon.

Room in the roof conversion – £35,000

Dormer loft extension – £50,000

Mansard extension – ​​£60,000 – £65,000

Hip-to-gable extension – £65,000

Loft conversions add much-needed extra space to your home. However, when deciding the type of loft conversion that offers maximum space, seamless integration, and aesthetics, professional opinion helps avoid pitfalls. The most important reason to hire professionals is bespoke designs and solutions that create unique spaces for your needs and the available attic space. Did you know that architect-conceived conversion plans can boost your home value? 

DIY projects often do not fully adhere to building control and planning guidelines, which can lead to lawsuits. Having planning experts on your team can prevent unlawful designs and construction features from the get-go. Professional expertise will save you time and money. Project management by conversion specialists ensures stress-free home improvements. 

We have years of experience as loft conversion specialists for Victorian and 1930s London properties. Our design-forward approach creates bespoke spaces that complement your home, lifestyle, and personality. Drawn by architects and overseen by structural engineers, our designs are modern, practical, and robust. There is no guesswork; we use 3D rendering to bring to life the outcomes. We offer a no-obligation contract at the end of the design stage to continue the project to the build stage.

Our technical specifications and structural calculations comply with building regulations and planning guidelines. We undertake paperwork related to pre-build requirements, assist with party wall agreements and work with local authorities. A qualified team of builders will work efficiently to meet completion day without delays. We offer project managers for all loft conversions to ensure quality control and time management. From the materials we choose to the warranties we offer, high standards prevail all the way. 

Converting your loft comes under permitted development rights that do not need planning permission. However, there are limitations. Certain loft conversion types, extension volumes, and design features require planning permission. We will guide you through those specifications and, when necessary, secure planning permission for you.

 

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.
