The Story So Far

The man behind
The London
Building Company

Freddie began his construction career at 15, joining a concrete restoration crew in Pimlico before he had left school. By 17 he was a skilled concrete repairer, working nights on the London Underground and training at college by day, first in tiling and then three years in plastering and fibrous work.

After qualifying he taught construction at Lambeth College for more than four and a half years, then became a site manager for a small building firm, where he found a passion for bringing projects to life. He went on to start his own business with rear extensions and loft conversions, and grew it into what is now The London Building Company.

Today Freddie personally oversees every project, working alongside a trusted team who have been with him for years. Together they share one mission: to make clients' dream homes a reality.

Straight From Our Clients

Over 100 five star reviews and counting

Homeowners across South East London have trusted us with the biggest job their house will ever go through. Here is what they had to say about how it went.

Now that the work has finished, we can honestly say that it has exceeded our expectations. We are absolutely delighted with the finished job which was completed on budget and with no extra costs. Freddie is highly organised, was always available when needed and his communications are always clear.

Simon Elworthy Side and rear extension, SE23

Freddie and his team were excellent: the quote was competitive, the schedule of work was clearly mapped out, and Freddie was on site very often to check on progress and answer our questions. From the very outset, we had total trust that Freddie and his team knew what they were doing and prioritised doing the work to a very high standard.

From start to finish a seamless, low stress experience. Excellent advice, straight talking, clear communication with an attention for detail. They are subject matter experts and a pleasure. Decent, kind, good business people doing an amazing job for their clients.

Before You Ask

The questions we get most

How long will my project take?

Timescales depend on the scope and complexity of the work. Once the project has been agreed, we provide a detailed programme with an estimated timeframe, so you know what to expect before work begins.

Do you work with architects and structural engineers?

Yes. We regularly work alongside architects and structural engineers, and can introduce you to trusted professionals if you are still developing your plans. If you already have a design team, we will work with them.

Do you manage Building Control?

Yes. Once the contract is in place, we manage the Building Control process, including liaison, arranging inspections and seeing it through to completion.

What if we want to make a change during the build?

We discuss any proposed change with you before going ahead, including its effect on the cost and the programme, so you can make an informed decision before anything changes.

Do you provide electrical and gas safety certificates?

Yes. Electrical and gas work is carried out by suitably qualified professionals, and the relevant certificates are provided on completion.
