Residential Project Feasibility: People Spend Hundreds of Thousands Solving the Wrong Problem

Clients Often Come With a Solution, Not the Need

One thing really crystallised for me at Grand Designs this year. I spent two days speaking to homeowners about their projects and, honestly, almost everyone came with a solution already fixed in their head.

• “I want a basement.”

• “We want to open this up.”

• “We want a rear extension to here.”

• “We want the kitchen over there and bifolds here.”

  
  

And there is nothing wrong with that in itself. It is their house, their money and usually something they have been thinking about for months, sometimes years. But what I noticed again and again was that people came with the solution, not the actual need they were trying to fulfil, and once that solution is fixed in their head, it becomes very difficult to properly explore whether it is actually the right answer.

I think this is one of the biggest missed opportunities on residential projects, especially private homeowner projects.

Why Value Engineering Is So Often Misunderstood

Quite often clients are resistant to spending time and money at feasibility stage, discussing different options, testing layouts, looking at how they actually want to live in the house and what would serve them best. They want to move quickly into design, planning and then construction because that feels like progress. Spending money on “thinking” feels expensive. Spending money on building feels productive, even when the decisions underneath it have not really been challenged properly.

And this is where I think value engineering is completely misunderstood.

Most people think value engineering means reducing specification later in the project. Cheaper finishes. Smaller rooflights. Less glazing. Different flooring. Cutting bits out once the project is already over budget.

But the reality is that the biggest opportunities to create value on a project usually happen right at the beginning, before the design is fixed and before everyone becomes emotionally attached to one particular solution.

Sometimes the best value engineering is not making something cheaper. It is making sure you are solving the right problem in the first place.

I have seen plenty of projects over the years where clients committed to very large basements, sometimes double-storey basements costing half a million pounds or more, adding huge complexity, risk and programme to the project, extending planning by a year or longer, only for those spaces to end up barely used a couple of years later.

Not because the projects were bad. Many of them looked fantastic. But somewhere along the line “more space” became confused with “better living”, and they are not always the same thing.

I have seen the same on a smaller scale as well. Clients pushing for the biggest extension possible because everyone now wants open-plan living, large kitchen islands and these huge continuous spaces you see all over Instagram and Pinterest. Then the project gets built and they realise that while the kitchen itself works well, there is actually no natural way to use the rest of the space. The circulation cuts through the middle of the room, there is nowhere obvious for sofas or TVs, dining areas feel disconnected and the whole thing somehow feels awkward despite being much bigger than before.

More Space Does Not Automatically Mean Better Living

The reality is that most homeowners know how they want to live, but they do not necessarily know how to translate that into space, and that is not criticism, it is simply not their profession.

Quite often people describe the physical intervention instead of describing the problem.

“I want a rear extension.”

OK, but why?

Is it because the kitchen feels disconnected from the rest of the house? Is it because there is nowhere for the kids to do homework together? Is it because they entertain a lot? Is it because they want more daylight in the centre of the building? Is it because they need better connection to the garden?

Those are completely different problems and they may lead to completely different solutions. Perhaps it is an extension. Perhaps it is a layout change. Perhaps it is using the existing building differently. Perhaps it is actually a smaller extension with a much better layout.

Most Homeowners Know How They Want to Live — But Not Necessarily How to Translate That Into Space

One of the guests on our podcast, architect Andrew Dobson, spoke very well about working with the existing building rather than automatically assuming the answer is simply building bigger, and I think that is something that is often missed now. Bigger is not automatically better. More square footage is not automatically a better home. Sometimes simplifying the layout slightly or reducing the extent of work actually produces a much better result overall.

And from the cost perspective, this matters massively because the big decisions are usually not the finishes at the end. They are the fundamental geometry of the project right at the beginning. Extension depth. Structural spans. Excavation. Roof complexity. Glazing quantities. Circulation inefficiencies. All of those things drive cost very quickly.

Bringing an extension in by two or three metres can sometimes save tens of thousands of pounds while having very little impact on how the house actually functions day to day. In some cases, simplifying the layout or reducing unnecessary area frees enough budget to actually keep the things clients really care about instead of value engineering them out later. Better glazing. Better joinery. Better landscaping. Better lighting. Better finishes.

The Biggest Cost Decisions Are Usually Made Right at the Beginning

Ironically, people will often resist spending a few thousand pounds on proper feasibility studies or early-stage cost advice while simultaneously committing to £500k, £1m or more worth of construction costs based on assumptions that have not really been tested properly.

And once the project moves forward, once planning is submitted and everyone becomes attached to the design, changing direction becomes much harder, even when the warning signs are already there.

This is also why architects quite often end up constrained very early in the process. They are no longer really exploring possibilities, they are trying to optimise a solution already fixed in the client’s mind. On larger projects there is usually more understanding of feasibility and option testing, but on smaller residential projects especially, clients quite often see that stage as something optional rather than probably one of the highest-value exercises in the entire project.

To be clear, this is not an argument against ambitious projects. Some basements absolutely make sense. Some large extensions completely transform homes. Some clients arrive with exactly the right instinct from day one.

But I do think more homeowners would end up with better projects if they spent a little more time defining the need before locking themselves into the solution.

Because the best projects are usually not the ones with the biggest footprint.

They are the ones that actually work properly for the people living in them.

If you are at the early stages of a residential project and want to properly test options, layouts and costs before committing too far into design and planning, that is exactly where early feasibility cost planning can add the most value, not by cutting quality later in the process, but by helping make better decisions at the beginning.
