    I started working in construction sites as cleaner back in 2005 and then joined a company that was carrying out commercial renovation for licenced premises, listed buildings and offices and then moved to other companies that were carrying out domestic works, such as loft conversions, extension, renovation and everything in between. I would like to think of our company as a 1 stop shop to all your construction needs, from planning to costing, from project managing to building and delivering.

    2VP - the design and build brand of 2V Projects Ltd, working across Fulham and south London. We take on whole projects rather than fragments: extensions, loft and garage conversions, full house refurbishments, kitchens, bathrooms, bespoke joinery and microcement finishes. One contract, one team, one point of responsibility. The difference is the system behind the work: - In-house quality control. A checker inspects the site independently of the people building it. - Daily site reports. You see what happened each day without having to ask. - Weekly invoicing tied to work actually completed. You pay for progress, not promises. - A live project dashboard. Real programme and cost position, available to you at any hour. - A standard book of quality that every subcontractor signs and is audited against. On price we are direct with you. We will rarely be the cheapest quote you receive. Low bids are won on optimism and recovered later through variations, which is why so many projects end up costing far more than the figure that persuaded the client to sign. We price the whole job at the start, including the parts most estimates quietly leave out. If you are still planning and want to understand what your project will genuinely cost, tell us the full scope - not just the extension, but the kitchen, the electrics, the bathroom, the decoration. One honest number now is worth more than a comfortable one you cannot rely on.
