A few practical starting points for making more of your home. Every property is different, so talk through your plans before choosing products or designs.
A successful extension should work with the way you live as well as the shape of your home. Start with what you need the extra space to do: a brighter kitchen, a larger family room, or a calm place to sit and look out to the garden.
Think about how people will move between the existing rooms and the new space. Consider where daylight enters at different times of day, what views you want to keep, and how doors will open onto the garden. A conservatory, glazed extension or roof upgrade can each create a different feel, so compare options against your budget and the character of your property.
Gather a few reference photos and note the details you like. A clear brief makes it easier to discuss materials, glazing and roof choices with your installer.
Windows influence the look of a property from the street and the comfort of each room. Before choosing a style, look at the proportions of the openings, the period of the house and the colours already used on the exterior.
uPVC and aluminium can suit different designs and preferences. Compare frame profiles, opening styles and colour options in person where possible. Also think about how you use each room: ventilation, easy cleaning and access all matter in day-to-day life.
Ask for a clear written quote that explains what is included, how the installation will be managed and how the finished work will be checked. Taking time to compare the full specification can help you make a choice that feels right for your home.
Start with the purpose of the door. A front entrance, patio opening and side access each have different priorities for appearance, everyday use and the space available around the opening.
For garden access, compare sliding and bi-folding designs. Sliding doors keep panels in a compact line, while bi-folding doors fold back to open a wider section. Check where the panels will stack, how the threshold meets the floor and whether furniture or paths affect the opening.
For an entrance door, consider the style alongside the surrounding brickwork, windows and hardware. Bring measurements and photos to your first conversation, then ask about available finishes, glazing choices and fitting details before you decide.
