The Loft Design Process

Initial Site Survey

Your journey with Clapham Construction begins with an in-depth site survey. Our team will visit your property to assess its suitability for a loft conversion. During this visit, we consider various factors such as structural integrity, available space, and your specific requirements. This initial assessment allows us to provide a tailored solution that aligns with your vision, budget, and timeframe.

Creating and Amending Designs

Once we have all the necessary information, our skilled designers get to work crafting preliminary plans. These plans are not set in stone; we offer amendments at no extra cost to ensure that the final design meets your expectations. This process can take between 1 to 5 weeks, depending on the complexity of the project and any changes you might request.

Submission and Approval

Upon your approval of the final design, we move on to the submission phase. This involves presenting your plans to the local authority for planning permission or permitted development rights. With an average approval time of around 8 weeks, our team stays on top of the process, making any required changes and ensuring a smooth approval process.

Why Secure Planning Permission Even If You Don't Build Right Away

Boost Your Property Value

In London’s competitive property market, having planning permission for a loft conversion can be a significant asset. It demonstrates the untapped potential of your property, making it more appealing to prospective buyers. The approval essentially serves as a seal of quality and potential, elevating your property’s market value.

Ease the Sales Process

Properties with approved loft conversion plans often attract serious buyers, reducing the time your property spends on the market. The planning permission acts as a stamp of approval, reassuring buyers and speeding up the sales process.

Clapham's Integrated Approach to Loft Conversion Design and Build

Cost-Efficient Design

One of the distinct advantages of choosing Clapham Construction is our integrated approach. While traditional architects may offer designs without considering the build costs, our team of in-house architects works in tandem with our construction experts. This ensures a design that is not only aesthetically pleasing but also cost-efficient, offering you the best value for your investment.

Single Point of Responsibility

Our design-to-build service means that all aspects of your project, from the initial sketches to the final construction, are handled by one team. This eliminates the complications that can arise when dealing with multiple service providers and gives you a single point of contact for all your needs. The result is a smoother process and a loft conversion that meets your exact specifications.
