Build was converting an open plan shop into residential (two bedroom flat).
Add 10% waste for all skirting, flooring and tiles.
Estimate the cost of the electics as you go along if they’re not defined by the architect or you’re diverging from what the building contractor has specified. Anything to do with getting a new supply of electrics or water costs at least a grand.
Patching the roof up was an unexpected expense.
Do all your fixtures and fittings the same colour? If you go for brass taps, say, does everything else match: sockets, window handles, ceiling roses, plug holes, light switches?

We went with white uPVC and changed the handles to silver. I’m fond of Velfac but we just went along with what the builder specified.
The kitchen and lounge ceiling are almost 3m high so I went for large skirting board. Also the standard ogee and torus profiles seem very fussy, bullnose is much simpler. Similarly for the architrave.
Working with architects
We initially used a traditional local architect but it was expensive and we weren’t that happy with the results and service. So we ended up submitting revised plans from Archiplan. These were much better value. However, the architect we chose didn’t come to site so there were some ommisions and features that didn’t work which may have been mitigated by coming in person. In hindsight I wish I’d had more involvement at this stage. Fortunately our builder was really savvy and challenged anything that didn’t make sense.
The most expensive quote was double the cheapest. We went for somewhere inbetwen.
We received wildly varying quotes for painting, the most expensive was thrice the cheapest.
Options were a little limited with this room. It was originally part of an original extension with a low flat roof, consequently the celing height after putting down the floor and insulation is only 2.1m. The online architect had had combined this room with the kitchen space but having not visited the site he didn’t realise the original external room was between.
Something not immediately apparent from the plans is that the back of the property is 600mm higher than the front. In the original plan the bathroom was on the lower level but the soil pipe was higher up at the back. The builder offered some solutions with pumps but ultimately the decision was made to relocate the bathrooms to the back and move the kitchen.
- Laminate worktop £98
A mixture of rads from various sources. Refurbished cast iron rads seemed cheap at £50 each but with sandblasting, lacquer and valves/stays they weren’t so cheap.
Went for stone tiles but didn’t realise you have to treat them before they were laid.
