About us
Eternal Design & Build
Led by a Chartered Builder, working from Edgware across North, West and Central London.

The company
Established February 2019
Eternal Design and Build Ltd was established in February 2019 and works from Edgware, Greater London, on residential construction and refurbishment across the capital and into Hertfordshire.
The company specialises in high-end and prime residential work: complete refurbishments, extensions, loft conversions, basement construction and technically complex building projects, together with planned and reactive building maintenance.
Eternal is led by Prakash Choudhary MCIOB, a Chartered Builder and Member of the Chartered Institute of Building, who has worked in construction since 2009 — more than fifteen years of industry experience. The company has worked on more than 300 properties across London, and the largest single project it has delivered to date was worth £1.6 million.
Our clients are private homeowners and their architects, interior designers, quantity surveyors, structural engineers and contract administrators, alongside landlords, managing agents and property portfolio owners.
Leadership
Prakash Choudhary MCIOB
Chartered Builder · Director

Chartered status
Chartered professionalism at the centre of every project.
Chartered status is held by the company’s director, Prakash Choudhary, as a Chartered Builder and Member of the Chartered Institute of Building. It reflects assessed professional competence in construction management, adherence to the Institute’s code of conduct, accountability, and a requirement for continuing professional development.
It is a statement about professional standing. It is not, and should not be read as, an endorsement, approval, warranty or guarantee by the Institute of any particular project.
Scope and boundaries
Eternal carries out construction works and manages the site. Structural design, temporary works design, waterproofing design, geotechnical work, heritage and conservation advice and planning applications are by the appointed consultants and specialists for each project. We build to those designs, and we raise anything on site that appears to depart from them rather than proceeding and asking later.
No membership, registration or accreditation of itself provides a warranty, guarantee, approval or insurance unless a specific warranty product has been purchased and issued in writing.
