Award- Winning & Proactive Architectural Design Studio in Herts
Founded by Mark Wiffen in 2010, a qualified Architectural Technician with extensive experience in the construction industry, Marlin Design specialises in providing architectural design services to homeowners in Hertfordshire & London. Through all our projects, we will look after you from instruction to start on site and provide you with a full set of approved documentation, enabling contractors to provide a fixed price quotation, based on approved designs. Our Architectural Design service encompasses a complete planning application service, including feasibility studies, architectural design, planning applications, drawing services and building regulations applications. Typical projects range from loft conversions and house extensions, to larger commercial and new build housing developments. We have a very comprehensive knowledge of quality, yet affordable products and can approach projects with a commercially and financially astute mindset and strive to create the most valuable Architectural design achievable for a project. During the design process it is a good idea to engage the services of an Interior Designer, and our inhouse Designer, is available to assist with your project on a full design/supervision basis on to present mood boards on a room by room basis. Please contact us directly should you need the services of an Interior Designer. Marlin Design Ltd can manage the entire planning application process or can provide individual services depending on your requirements. Contact us today to learn more about how we can help with your project.
