North London
Houses With More Potential
Many period North London properties feature compartmentalised layouts with dark rear kitchens. We specialise in opening up ground floors using custom RSJ steel framework to create fluid living and dining spaces connecting to gardens.
By coordinating temporary structural propping, Thames Water drainage build-overs, and level thresholds early, we prevent site surprises.
North London
Designed Around the Way You Live
We balance period restoration (such as cornicing, ceiling roses, and timber sashes) with modern acoustic insulation, underfloor heating, and architectural glazing.
Our single-contract management ensures neighbour considerations, party wall awards, and strict borough planning rules are handled smoothly.

✓What you need before breaking ground for this project:
- 01.Permitted Development check or Lawful Development Certificate application
- 02.Structural engineering calculations for steel framework & patio door spans
- 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."
Unsure about your property's specific planning constraints?
Costas personally reviews drawings and property history during our free founder site consultation.
