Builder recommendations (Bromley area)

[TwinDad10]

Can anyone recommend an experienced building firm in the Bromley/Hayes/Orpington/West Wickham area for a full house renovation and kitchen/diner extension please?

We’d prefer to use a design/planner/build service rather than a separate architect (I’ve heard too many scare stories of paying architects £££ only for them to produce plans that will never come in on budget!) My assumption is if the same firm does everything, it’s more likely to go smoothly (?)

The structural problem with design-and-build is that the same firm designing and constructing your home has a commercial incentive for the design to be cheap and easy to build — not necessarily better for you to live in. An independent architect sits on your side of the table. They're optimising for your outcome. A D&B contractor's design team is optimising for their margin, which tends to show up in things like ceiling heights, window sizes, and material choices — the decisions that are invisible in a quote but make a real difference once you're living there. Architects will think of things you and your builder wouldn't.

On the over-budget drawings: that's a genuine frustration, but it's usually a failure of early communication rather than an inherent problem with using an architect. A good one should establish a realistic budget from the first conversation, cost-check at key stages, and design to that number — not produce something aspirational and hope it works out. Worth asking any architect you interview how they handle budget at the outset.

Great advice. Appreciate it
