Interior layout and space planning from £385
A good layout is the difference between a house that is big and one that works. We survey your rooms and draw layouts to scale, with furniture, doors and circulation, so you can see what fits.

The short answer
Space planning decides where walls, doors, stairs, kitchens and bathrooms go inside a house, so every room is the right size for its use. We survey the house and draw the options to scale. The fee is £235 drawings + £150 survey (£385 total), no VAT to add, with the survey included in the total.

- A measured survey of the floors you want to re-plan, with structure and services noted
- Existing plans drawn to scale, as the base for the new layouts
- Two layouts with furniture, doors and circulation drawn at scale, so you can see what fits
- Checks on stairs, escape routes and ventilation, so a layout you like can also be built
- A note of which walls are likely to be structural, so you know the cost of each move
- A plan you can hand to a builder, or build on with our building regulations drawings

Brief
You tell us how you use the house and what is not working.
Survey
We measure each room, door and window, and note walls, chimney breasts, pipes and stairs.
Options
Two layouts, each drawn to scale with furniture, so you see what fits.
Check
We test each against stair, escape and ventilation rules.
Choose
You pick a layout and we say what permissions and drawings it needs next.
Sizes that make a layout work
The nationally described space standard is a useful yardstick even for existing homes: a single bedroom at least 7.5 square metres and 2.15 metres wide, a double at least 11.5 square metres, and one double 2.75 metres wide. Councils use it for new homes, and it tells you when a room is too small to use as a bedroom.
We draw furniture at scale so those numbers become pictures: a double bed with space to walk round it, a wardrobe whose doors can open, a table that seats six.
- Single bedroom: 7.5 m², at least 2.15 m wide
- Double bedroom: 11.5 m², one at least 2.75 m wide
- Doors, drawers and radiators drawn in, not forgotten
The stair and the way out
Moving a stair is the most expensive change in a layout. Approved Document K asks for 2 metres of headroom on a stair, with a reduced figure allowed in a loft conversion. For a house with a floor above 4.5 metres, Approved Document B asks for a protected escape route to the front door, which is why a fully open plan is not always possible.
We draw the stair and the escape route first, because they limit everything else. A layout that ignores them can look good and still fail building control.
Light, air and services
A new bathroom or kitchen needs ventilation and a place for the drain. Approved Document F sets purge ventilation openings as a share of the room’s floor area, and a room with no window needs mechanical extract. We mark the drain runs and the extract on the plan, because they decide where the wet rooms can go.
If your layout needs a wall removed, we say whether it is likely to carry load and point you to our structural calculations.

Questions about space planning
Do I need planning permission to move internal walls?
Usually not, because works affecting only the interior of a building are not development. Building regulations still apply, and a listed building needs consent for most internal work.
Can you design the kitchen and the fittings?
We plan the space, the doors and where services run. Choosing fittings and finishes is for your kitchen designer or interior designer, and our plan gives them the exact dimensions.
Is the survey really included?
Yes, the total shown above includes the survey. It is the same measured survey we use for drawings, so it can be reused if you go on.
What if I want to extend as well?
Then the layout belongs inside an extension design. See rear extension drawings, which can include the new layout.
