Working in Hertfordshire
A single team from first idea to finished home.
Orama Design & Build is based in Potters Bar, making Hertfordshire our home county. From family homes needing modern open-plan living to comprehensive residential renovations, we focus on making existing houses work seamlessly for how families live today.
With generous post-war semis, 1930s detached homes, and village cottages across Welwyn, Radlett, and Cuffley, we coordinate architectural design, planning permissions, Thames Water/Affinity Water build-over approvals, and structural delivery as one joined-up process.

Space That Works Better for Everyday Life
Most Hertfordshire homeowners want a functional, light-filled ground floor: an expansive kitchen-diner, a dedicated utility room, and seamless garden connectivity. Before architectural drawings, we assess structural load paths, drainage runs, and sunlight orientation.
This early technical clarity ensures RSJ structural steels, underfloor heating, and high-performance glazing are engineered together without delays.
Hertfordshire
Thoughtful Design. Carefully Delivered.
Whether planning a single-storey rear extension, a dormer loft conversion, or full interior refurbishment, we sequence trades to protect living areas and maintain tidy, considerate sites across residential Hertfordshire roads.
Founder and master builder Costas Joannides oversees every stage directly—ensuring one point of contact from first survey through to handover.
A considered approach to extending and transforming the existing home.

- 03.Party Wall Section 6 notice for foundation excavations within 3m of neighbour
- 04.Thames Water / Affinity Water Build-Over Agreement
- 05.Building Control stage inspections (foundations, DPC, steelwork, insulation)
Master Builder's Advice — Costas Joannides (45+ yrs experience)
"If you want maximum glass width with slim aluminium sliding doors, calculate your steel goalpost early. A steel goalpost frame eliminates the need for bulky corner brick piers."
