Choosing the Right Window Style for Your Space

The Dilemma

Windows shape both the character and comfort of a home. They control daylight, views, ventilation, proportions and the overall feel of a room. Yet most homeowners choose windows late in the process, in a rush, based largely on what a supplier happens to offer.

The dilemma is simple: how do you choose windows that improve the architecture rather than fight it?

The Options

Option 1: Slim-Frame Contemporary Windows

Aluminium or composite systems with very slender frames.

Pros:

• maximises daylight

• clean lines and uninterrupted views

• suits modern extensions

Cons:

• can feel out of place on traditional homes

• higher cost

• reduces visible structure

Option 2: Standard PVC or Timber Windows

The typical choice for most homes.

Pros:

• cost effective

• available in many configurations

• visually stable

Cons:

• thicker frames reduce glass area

• proportions sometimes overlooked

Option 3: Divided-Light or Multi-Pane Windows

Windows with bars or muntins, whether real or applied.

Pros:

• suits traditional or historic properties

• adds texture and character

Cons:

• fake applied bars can look flat or inauthentic

• can obstruct views

The Decision Criteria

1. Architectural Language

Openings should suit the building.
If your property has a strong period style, very minimal frames may jar.
If your home is modern or your rear extension is contemporary, slim frames can work beautifully.

2. Proportion and Rhythm

Windows must make sense as part of the elevation.
Ask:
• Do the tops align horizontally?
• Do divisions relate to internal elements?
• Does the height suit the ceiling?

A poorly proportioned window will always feel wrong, however beautiful the frame.

3. Daylight and Orientation

South-facing rooms can handle deep frames and still feel bright.
North-facing rooms benefit from slender frames and generous glass area.

4. Ventilation Strategy

Think about operable sections rather than defaulting to a single opening.
A mixture of fixed and opening panels often gives the best balance.

5. Interior Use

Internally, window sill heights matter.
Low sills create seating opportunities.
High sills work behind furniture.
Full-height glazing has impact but limits storage and radiator placement.

6. Maintenance and Longevity

Timber offers beauty but requires upkeep.
Aluminium lasts decades with minimal maintenance.

The Recommendation

Choose windows based on architecture first, material second and cost third.
A slim-frame unit in the wrong style of house will look forced.
A PVC unit in a contemporary extension may dilute the design intent.

Where possible, simplify your window palette: one or two frame types used consistently across the house feels deliberate and refined.

A Quick Tip

Photograph your house from the front, print the image, and lightly sketch the window layout on top. This quickly reveals whether proportions and alignments are working.
