Client-side residential project management

A renovation project manager for homeowners in South West London.

Independent, client-side project management for extensions, loft conversions and whole-house renovations — protecting your time, keeping pressure on the budget and helping the build run more smoothly.

If you are looking for a residential project manager in London, this is a client-side practice: appointed by the homeowner, not the builder. The fee is 10–12% of the project cost. South West London is the core, and the neighbourhoods actually covered are listed on the areas page — he does not pretend to cover every borough.

Example project

A kitchen and side extension in Wimbledon: a £180,000 contract, delivered under £150,000.

The detail, sequencing and decision-making behind the finished result — not just the finished photographs.

Groundworks, structural steel, roofing, first-fix services and a fitted kitchen, coordinated across the structural engineer, builder, joiner and specialist suppliers. Steels ordered ahead of the week they were needed, so the site was not paying to stand still.

Working for you
For busy homeowners

A renovation shouldn't become your second job — or cost more than it should.

I manage the builder, the budget and the decisions — and keep a price-sensitive eye on every quote, so you don't quietly overpay.

Why the service pays for itself

Save more than you spend on my fee.

I catch problems early, challenge unnecessary extras, and buy smart — trade-price materials wherever I can, not retail.

Trade-price materials

Where possible I source materials directly at trade prices — savings that go to you, not a builder’s mark-up.

A price-sensitive eye

I challenge quotations and allowances line by line, so you’re never quietly paying over the odds.

Protect your time

Builder questions, site visits and daily coordination — handled, so they don’t land in your working day.

Avoid expensive delay

Late decisions and missing information stop work and cost money. I keep things moving.

Trade-price sourcing alone often covers my fee.The rest is fewer surprises, faster decisions, and your time back. Readwhat a project manager costs.
What I manage

Extensions, loft conversions and full renovations.

One experienced, price-sensitive project manager for the whole build.

How it works

Calm, organised support at every stage.

01

Understand

We establish your project stage, team, budget, risks and where you need the most support.

02

Structure

I put clear systems around decisions, costs, variations, communication and reporting.

03

Manage

I attend site, deal with questions, monitor progress and keep you properly informed.

04

Complete

I help coordinate snagging, outstanding work and the final steps towards handover.

Independent homeowner representation

"I understand the pressures on site, but I am appointed by the homeowner. My job is to bring clarity, ask the right questions and protect the client's time and budget."

What clients say

Happy clients, in their own words.

Ben was an absolute godsend and honestly could not have coped without him on our project. He kept everything calm throughout and was only a call away whenever we needed him.
Catherine & RobWandsworth
We are so glad we found Ben. He was recommended to us on our street WhatsApp group. If you are considering a project manager for your build, we can’t imagine anyone better. His knowledge and ability to problem solve saved us so much stress and money!
Anita & SimonFulham
We instructed Ben mid-build as we were finding it too overwhelming with a newborn and work commitments. From our first meeting we knew it was the best money we could spend. Ben was always one step ahead of our builder and saved us so many headaches. We absolutely love our home.
Kaninka & DanEast Sheen
Ben was by far the best thing we invested in for our project — there is no way this could have happened without him. We were not in London for the whole project; everything was done remotely, through Ben and the builders. Recommending him is an absolute no-brainer.
