Renovation project management in Clapham.
Client-side project management for homeowners extending or renovating in Clapham, from Clapham Old Town to Clapham Common.
There is no fee for the initial conversation, and if you already have builder quotations I will review them line by line at no charge. A kitchen and side extension I managed in Wimbledon was brought in under budget — read the case study.
Clapham's Victorian terraces are well suited to the kitchen-diner side-return extension that's become the default upgrade for growing families here — opening the ground floor into the garden while leaving the rest of the house largely undisturbed. A loft conversion adding a third bedroom or a second bathroom is the other common route, often done in a separate phase either before or after the ground floor.
The Clapham Conservation Area covers a significant part of the borough, which means front elevations, rooflines and materials are more tightly controlled than a street outside it, and some permitted development rights may not apply. It's worth checking the specific designation for a property before a design is drawn up around an assumption that turns out to be wrong.
Coordinating structural engineer, builder and specialist trades on a project like this — while keeping a live budget and catching quotation omissions before they're signed off — is what a client-side project manager adds, without any commercial relationship to the people doing the building work.
Planning in Clapham. Clapham addresses can fall in Lambeth or Wandsworth, so check which council covers yours. Lambeth says its 62 conservation areas cover approximately 30% of the borough, with Article 4 directions in all or part of nine of them; Wandsworth has 46 conservation areas and Article 4 directions in all or part of eight. Our permitted development guide covers both councils, with links to their maps.
Before you commission drawings, the extension cost calculator and loft conversion cost calculator give a sourced London build range for a side return or a loft, ex VAT.
Local considerations
Clapham straddles Lambeth and Wandsworth, so confirm which council covers the address before assuming any permitted development position. The planning permission checker and the permitted development guide link to both councils' maps; how long planning permission takes in London and the extension and loft timeline calculator cover the programme.
Most terrace jobs still need a party wall agreement. Budget separately for building control fees — Lambeth's published figures are in that guide — and a contingency.

A Clapham job, not a generic one. The case study closest to this page is in Clapham itself: a £600,000 conversion of a period house into three self-contained flats, for developers based outside London. The part that carries over to a family house here is the floor structure. Between flats it had to meet fire and sound separation, so it was rebuilt with engineered joists rather than patched, because being told to open it back up at inspection costs far more than doing it once. Read the Clapham case study.

Four quick details. You do not need drawings, a builder or a budget yet.
What happens next: it comes straight to me, not a call centre. I aim to reply within one working day, usually to arrange a short call. No fee for the conversation and nothing to commit to.
Email me your builder’s quotations for a free line-by-line review.
I will read them properly and come back to you on what is excluded, which “prices” are really provisional sums, and what I would want answered before anyone signs. If the quote is sound, I will tell you that too.

Support at the level Clapham projects need.
From a one-off review of quotes already in hand, to full day-to-day management of the build.
No two projects are the same.
Some homeowners want the full service — quotations reviewed before anything is signed, then day-to-day management right through to snagging. Others simply want the reassurance of having someone they trust on their side during the build, without the fees that come with asking an architect to do it. Most people sit somewhere in between.
So there is no fixed price list. Tell me what you are building in Clapham, where you have got to and how involved you would like me to be, and I am sure we can work something out.

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.
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!
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.
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.
Tell me what you're building, and I'll suggest where to start.
No charge for the initial conversation — just a clear read on what your project needs.
