The Home Project Podcast

An expert project management approach is essential for a successful home renovation. In this episode of The Home Project Podcast, hosts Tina Patel and Bart Kolosowski sit down with Neil Kahawatte, an architect specialising in private residential projects. Together, they unpick the misunderstood role of a project manager in domestic builds, exploring why professional guidance is the ultimate key to avoiding costly pitf...

Why does your structural engineer cost you more than expected?

Engineering fees often take the blame, but the real cost drivers lie elsewhere.

This episode unpacks what a structural engineer does on a residential project, from foundations and load paths to deflection and embodied carbon. We look at the design decisions, not the fees, that push steel tonnage and construction costs up.

We also cover underpinning, why it is one of the...

Do you know if your renovation actually needs a party wall notice?

Most homeowners assume the Party Wall Act exists to stop them building.

In this episode, we unpack the Party Wall Act with a chartered party wall surveyor, covering exactly which works trigger it, from loft conversions and rear extensions to basement digs and chimney breast removals. We explain the notice periods, the difference between consent and a formal award, a...

Are your renovation decisions quietly draining your budget?

The advice to get a structural survey is well established. The advice to get professional input before you even make an offer is not.

In this episode, we dig into the decisions that add cost without improving your home. Buying a property without the right professional input, skimping on surveys, engaging contractors before there is anything to price against. We cover what ...

Should budget or design come first?

The assumption is that a design can always be scaled back once the costs land.

We explore why setting a budget and developing a design in isolation is one of the most costly mistakes in residential projects. We cover what happens when design runs ahead of budget, why early-stage cost planning is essential, and how hidden costs, from structural work and party wall obligations to long lead-time mat...

Are you spending money before your project has even begun?

The assumption is that the sooner works start on site, the sooner the project is finished. In reality, a premature start is one of the fastest ways to waste significant money.

We cover where the real pre-construction money traps are, from missing permissions and party wall awards to CIL charges, overcomplicated building management systems, and the VAT savings most homeowner...

Is your renovation idea as viable as you think it is?

The figure in a homeowner's head and the layout they've settled on are rarely either accurate or final.

We explore how to properly stress-test a project before it costs you serious money. We cover how the brief-writing process uncovers what you need, why hand-drawn sketches outperform any online room planner, and how to approach budget conversations honestly from day one.

We als...

Is the planning system really as unpredictable as everyone says?

Plenty of homeowners treat a refusal as a catastrophe and an approval as a green light to break ground. Neither assumption holds up.

We walk through the entire planning process from first principles. That means understanding whether your project needs full planning or permitted development, how to structure an application that makes it easy for a planning officer to s...

What if you could see every planning delay coming?

The delays most homeowners fear are more predictable than they think.

We sit down with Geoff Megarity, planning consultant at Bell Cornwell, to map out exactly where delays hide and what you can do to get ahead of them. From the validation checklist to ecology survey seasons, Geoff explains the preparation that separates a smooth five-month process from one that drags on for eighte...

Do you really know what your permitted development rights allow?

The rules are nationally set, locally interpreted, and full of conditions that can catch even experienced owners out.

We cover what permitted development allows: extensions, loft conversions, outbuildings, and barn conversions. We explain where the rules get complicated, why the same street can have completely different rights, and how conservation area...

Is planning permission as frightening as everyone says?

Planning is a black box where decisions are made arbitrarily, and outcomes are impossible to predict.

We cut through the confusion with chartered town planner Aaron Zimmerman of Centro Planning Consultancy. We cover what constitutes development, the difference between permitted development and full planning permission, how the eight-week determination process works, and what y...

What decisions shape the success of a home build?

A residential project can take three to four years, yet many of the most important decisions happen long before construction begins.

In this episode we walk through the entire project journey, from setting the brief and budget through to selecting the design team, securing planning approval, tendering contractors, and managing the construction phase. At each stage we highlight where...

Do you know what actually changes the moment you get the keys?

Handover feels like the finish line, but for most homeowners it marks the start of a process they have never been prepared for.

We cover everything that happens at the point of practical completion: what the term legally means, why the contract administrator holds the only authority to issue it, and what changes hands the moment that certificate is signed.

We walk throu...

Is your build being managed, or just happening?

The build phase feels like the moment everything finally comes to life. But without the right management structure in place, it's also where home builds quietly unravel.

We cover who is responsible for what once work starts on site, why 80% of disputes trace back to decisions made at tender, and why the Contract Administrator works for the contract, not the client.

We also look at the...

Is your contractor selection process setting your project up to fail?

The assumption is that once you've found a builder and agreed a price, the hard part is over.

Between us, we've spent 40 years on high-value residential projects, and contractor selection is consistently the decision clients underestimate most. In this episode, we break down why choosing on price and gut feeling is a costly mistake, and how a structured process, ...

How do you protect yourself from costly disputes?

Signing a JCT contract guarantees protection and clarity throughout your build.

We break down the most common procurement routes and explain why choosing the right contract matters more than most homeowners realise.

Traditional lump sum contracts give you maximum control over specification and finishes but require complete design before tender and can extend your programme. Design a...

How do you avoid costly delays on a build?

Planning permission approved is just the beginning, not the green light to start building.

We break down the eight RIBA stages that structure every successful residential project, from initial feasibility through to post-occupancy evaluation.

Through our combined experience as architect and quantity surveyor, we explain why spending time on technical design prevents six-figure cost overrun...

Why does your day one budget never match your final cost?

That first figure feels fixed, but it's actually just the starting point for a journey of controlled change.

We walk through every stage of cost control, from initial budgeting to final account settlement. As an architect and quantity surveyor, we explain why early builder estimates carry risk, how professional cost planning builds in allowances for design variability, and w...

Are you choosing the right design team for your home?

Getting this decision right is an essential part of a successful home build project.

In this episode we explore why appointing the design team is the second most important decision in any high value home build, and how that early choice influences cost, risk, programme and quality from day one. We unpack what a design team really is, who should lead it, and how that changes as p...
