Apartment Floor Planning for London Flats
London flats have unique constraints — period conversions, bay-fronted terraces, narrow floorplates, and small reception rooms. Plan in metric, around the quirks, with apartment-scale pieces.
Start PlanningWhat Makes London Flats Different
London's housing stock is mostly Victorian and Edwardian terraces (long, narrow houses converted into flats), with newer post-war and contemporary buildings layered in. Period conversions take a single house and split it into 2–4 flats — usually a ground floor flat (with garden access), one or two middle floors, and a converted attic (loft conversion).
Reception rooms (the British term for living rooms) are often small by US standards — 12×14 feet is typical. Bay-fronted terraces project a bay into the front room; rear extensions add a kitchen-diner space; loft conversions provide a primary bedroom with sloped ceilings.
Furniture in London flats is generally apartment-scale — standard UK sofas at 200cm (79") are smaller than US standard sofas. Plan in metric throughout; mixing units causes errors.
Layout Problems You'll Actually Face
Bay-fronted reception rooms
Bay windows in the front of a terrace flat eat wall space. The bay itself fits a small bench or low pieces; the rest of the reception room has to absorb the dining table, sofa, and TV.
Loft conversion sloped ceilings
Converted attics have sloped ceilings to the eaves. Beds under the slope; standing-height activities under the peak; short storage against knee walls.
Small kitchen-diners
Period conversion kitchens are often small. Modern rear extensions add a kitchen-diner space; older conversions have a galley kitchen separate from a small dining area.
Period features that constrain layouts
Original fireplaces (often non-functional but kept as features), picture rails, ceiling roses — all affect where pieces can go and how high they can be.
How to Plan a London Apartment with Room Sketch 3D
Metric scale drawing
Centimeter-accurate snap-to-grid for UK measurements. Project settings let you switch to centimeters before drawing.
Bay window and chimney breast support
Draw bay projections and chimney breasts as fixed features. Plan furniture around them.
Loft conversion modeling
Sloped ceilings and dormers model accurately in 3D. Plan the bed under the slope; verify standing height under the peak.
UK furniture sizes
Custom-size feature handles UK retailer dimensions (cm) accurately. The 350+ library scales appropriately for UK use.
Path-in for narrow staircases
Period terrace stairwells are narrow and turn sharply. Verify path-in for sofas before ordering — many UK flats have refused-delivery sofas.
Step-by-Step for London Apartments
- 1
Measure in centimeters
UK furniture is sold in cm; UK rooms are measured in cm or meters. Pick metric in Room Sketch 3D's project settings; mixing cm and inches produces errors.
- 2
Draw the actual room shape
Period conversions have non-standard angles, projecting bays, and chimney breasts. Mark every fixed feature.
- 3
Mark loft slopes if applicable
For converted attics, mark the slope angles and knee wall height. The 3D view shows where tall pieces fit.
- 4
Plan reception room around bay and chimney
Bay windows fit benches or low pieces. Chimney breasts are fixed visual anchors — sofa typically faces or is positioned against the chimney breast wall.
- 5
Verify path-in for big pieces
UK staircases turn sharply. Sofas and beds often need to be disassembled or chosen specifically for narrow stairwell access. Verify before ordering.
Typical London Apartment Dimensions
| Apartment Type | Square Feet | Bedroom Size |
|---|---|---|
| Studio (bedsit) | 150–300 | Combined with living |
| 1-Bedroom (period conversion) | 400–600 | 10×11 to 12×13 |
| 2-Bedroom (terrace conversion) | 550–850 | Mixed; smaller often <100 sq ft |
| Loft conversion (1-bed) | 350–550 | Limited standing area; rest under slope |
| New-build 1-bed | 450–650 | 10×12 to 12×14, more uniform |
Frequently Asked Questions
Can I plan a London flat in Room Sketch 3D?
Yes — Room Sketch 3D supports metric measurements (cm), and handles period conversions, bay windows, and loft slopes accurately. $9.99 one-time, no subscription, on web, iPhone, iPad, and Android.
Does the furniture library include UK pieces?
350+ pre-measured pieces are dimensionally accurate regardless of region — a queen bed at 60×80" is the same as 152×203cm. Use the custom-size feature for specific UK retailer pieces.
How do I plan around a chimney breast?
Mark the chimney breast as a fixed feature. Furniture is typically arranged with the chimney breast as a focal point or visual anchor. Tall pieces (bookcases) flanking the breast are common; the alcoves either side often hold deeper furniture.
What about loft conversions with sloped ceilings?
Mark slopes in Room Sketch 3D's wall heights. Bed goes under the slope; desk and standing activities under the peak; low storage against knee walls.
How much does Room Sketch 3D cost?
$9.99 one-time. Useful for every London move and the inevitable period-conversion furniture puzzle.
