Velina Developments

Residential developers · Northern Ireland

Low U-value homes, built block by block.

We build energy-efficient homes exclusively with the Ecobrix woodcrete insulated concrete formwork (ICF) system. Wall U-values of 0.15 W/m²K or better mean warm, quiet, solid homes that cost less to heat from the day you move in.

Discuss your project How ICF works

Available for Hire or Partnership

From one cottage to a thousand homes

Whether you're a landowner, an investor, a housing association or a family planning a home of your own, we can deliver it with the same ICF build system and the same attention to detail.

Single homes & cottages

Self-build partnerships, replacement dwellings and rural cottages built to a high thermal standard.

Apartment blocks

Multi-storey residential schemes where a monolithic concrete frame brings structural strength, high fire resistance and acoustic separation between units.

Housing developments

Phased developments of up to 1,000 homes. A repeatable build method keeps quality and programme consistent across every plot.

Our build system

Why we build only with Ecobrix ICF

Ecobrix wall units are made from woodcrete: recycled softwood that is mineralised and bonded with cement, and pre-insulated with PIR on the external face. The hollow units are dry-stacked on site with no mortar and then filled with concrete. The result is a monolithic reinforced concrete wall wrapped in continuous insulation.

  • Low U-values

    Insulation wraps the outside of the concrete core across the whole envelope. Walls go beyond Building Regulations and can be taken to Passivhaus levels with extra cladding insulation.

  • Airtight by design

    A continuous concrete core and excellent junction details cut air leakage and thermal bridging, which lowers SAP figures and reduces the need for renewables.

  • Thermal mass

    With the insulation outside the concrete, the wall stores heat and releases it back into the room. Heating bills stay low and indoor temperatures stay steady.

  • Strong, safe & quiet

    Woodcrete is inert and won't burn. The dense concrete core gives structural strength and excellent sound insulation between rooms and homes.

  • Built in all weathers

    Units dry-stack without mortar and concrete can be poured in temperatures that would stop brick and block laying. That keeps Northern Ireland programmes moving.

  • Sustainable & durable

    Made in Britain from 60% recycled wood that would otherwise go to landfill. Woodcrete won't rot or decay and is vermin and insect proof.
