Synerga Group
estate  + landscape management


We are… Synerga Group, a privately held SME company based in Menen, Belgium.

Our origins… go back to 2018 and even before. In 2018 Synerga Consulting & Services, a niche specialist real estate & legal advisory firm founded by Willem Demonie in 2014, was taken over by a company that was called Synerga Group, to continue the use of the Synerga brand.

  • Synerga was founded in 2014 as an independent consulting company specialised in retail expansion consulting and legal services.
  • In 2016 our services were extended by offering real estate letting, brokerage and management services, respecting the BIV/IPI regulations for authorised real estate brokers on the Belgian market.
  • In 2018, a couple of months before the takeover, the business line “GREEN SERVICES” was developed by Synerga Consulting & Services, offering landscaping and gardening services, complementary with our property management activities. We also do subcontracting for other green professionals and horticulturists.
  • Since 2019 we deliver a broad scope of estate and landscape management services: asset management, property management, letting, brokerage, landscaping services for institutional and non-institutional investors, family offices, companies, and also to consumers.

About our name… Synerga is a registered trademark and it refers to the old Greek word synergia, meaning “working together”. Strategic partnerships and long-term professional relations are a very part of the Synerga DNA.
The ‘a’, in Synerga refers to “agility”, referring to the combination of different skills like flexibility, strength and coordination.  We have opted to add “group” in our company name, to reflect the broad scope of specialised services offered by our company.

About our  team… Willem DEMONIE, founder and managing director of Synerga Group has a rich history in green and agricultural services (born and raised in the many greenhouses on the family’s farm estate). His professional career started in 2006 with two internships at Redevco Retail Belgium, followed by a position as consultant at Structura Business Property (currently Structura.biz). As from 2008 Willem worked as expansion and real estate legal manager at retail organisations like Granita (currently Rougegorge), Tape à l’Oeil France and H&M Hennes & Mauritz Belux. In 2014 he became Real Estate Developer at Mitiska REIM, for which we are currently acting as exernal Asset Manager. Willem obtained a law degree (cum laude) at KU Leuven (2007) and more specialisation (Postgraduate Real Estate, KU Leuven 2008, LL.M Notary Law (cum laude) VU Brussels 2018). Currently he is following the 3-years Master Gardener course at Syntra Midden-Vlaanderen.

About our way of working… Our approach is simple: down to earth, solution-minded, a lean organisation, a good combination of theory and reality and value creation through active client-oriented work.

Estate and landscape management may look very different at first sight but they are all very natural for Synerga Group and combine well together, in true synergy, just like real estate surrounded by a nice landscape.

Waarom is deze site in het Engels?

Dit is een tijdelijke website, in afwachting van een meer professionele site. Omdat heel wat van onze activiteiten (vooral estate management) gebeuren in een internationale context, hebben we gekozen om deze tijdelijke site in het Engels te maken, de huidige commerciële lingue franca.

Pourquoi est ce site en Anglais?

Le présent site web est un site temporaire, en attendant un site plus professionel. Etant donné qu'un grand volume de nos activités en estate management se réalisent dans un contexte internation, nous avons choisi pour faire ce site temporaire en Anglais.
