About Us

Spiros Defteraios has studied Architecture between 1998 and 2012 in both UK and Greece and he has gained postgraduate qualifications in the field – capable to provide him with RIBA – Part III exemption.


He is today registered with Architects Registration Board, Chartered Member of Royal Institute of British Architects and a Certified Project Management Associate (IPMA Level D) after attaining the required standard to be awarded the APM Project Management Qualification (PMQ).


He has finally been issued with a Construction Skills Certification Scheme (CSCS) Title & Card from CITB for Managers & Professionals.


Spiros’ commitment to Architecture has led him to undertake most of his studies on a Part-Time basis while working in Architectural & Design Practices at the same time. This opportunity has provided him with the ability to combine the theoretical element, provided by his education in Architecture, with the practical and technical aspect of the profession given by the working environment he was part of throughout his studies.


Since 2002, Spiros has been working in the West & East Midlands Regions and also nationally in the UK and internationally in mainland Europe. 18 years of experience in combining the artistic and aesthetic element of Architecture with the practical and technical aspect of construction, has provided SD Studio with a series of successful projects that we take particular pride of.


Spiros is always keen on taking in any challenging projects and transform the ‘constraint’ into an ‘opportunity’ for our clients.



Dimitris Spiliotopoulos has studied Architecture at Birmingham City University and the University of Kent from where he has graduated with a BA (Hons) and a Master of Architecture.


Since 2010 he has been working in both Greece and the UK and has gained solid experience in architectural projects, commercial and residential, graphic design and visuals.

He has a very strong passion for conceptual design and is always excited to transform his ideas into real-life projects.



Roberta Pikelyte graduated from Plymouth University in 2017, with an Undergraduate Degree in Architecture, completing the first three years of her Architectural Education.


Since then she has been trying to find ways to combine her two passions – conceptual design and connecting with the different people around her, while continually improving her visualising skills and learning about the various elements of Architecture.
