Whether you’re embarking on a large-scale development or a home renovation, selecting the right internal and external doors matters more than you may think. Learn about common types of doors, explore the best doors available and get an insight into the emerging interior design trends for 2025.  

Do doors add value to a property?

Don’t overlook doors during a property development or home renovation. Why? There’s a multitude of reasons.

Doors significantly impact a property’s kerb appeal, creating a first impression for visitors and potentially influencing market value. Beyond aesthetics, they play a vital role in security, protecting homes from intruders and providing peace of mind for occupants. Energy efficiency is another factor – well-chosen doors minimise heat loss and reduce energy bills.

Internally, doors define spaces, offer privacy and contribute to the overall flow and functionality of the home. Compliance is also key as internal fire doors are required by UK law in certain areas of a home. This helps protect residents and prevent the spread of fire and smoke.

Investing in quality doors (both internal and external) is a long-term investment that enhances a property’s comfort, security and value. This makes this often overlooked design feature a worthwhile consideration during any property development or renovation project.

External doors
Security, style and sustainability

The primary function of an external door is to protect properties from the elements and intrusion. Durability, security and energy efficiency are paramount. Here are some top choices:

Composite doors
These doors combine a solid core (often made from engineered wood or foam) with a durable outer skin (typically GRP – Glass Reinforced Plastic). They offer excellent security, weather resistance and insulation, requiring minimal maintenance. Modern composite doors are a popular choice for their blend of practicality and style.  

Solid wood doors
A classic option, solid wood doors help to introduce natural textures and tones. Also, they can be customised to match any architectural style. Hardwoods such as oak, mahogany and walnut are popular choices. However, wooden front doors require regular maintenance to prevent warping and cracking and can sometimes be less energy-efficient than composite doors.  

UPVC doors
Un-plasticised Polyvinyl Chloride (UPVC) doors are a budget-friendly option known for their durability, low maintenance and energy efficiency. While they may not offer the same luxury appeal as wood or composite doors, they’re a practical and polished choice for many applications.  

Aluminium doors
Known for their strength and sleek look, aluminium industrial look doors are becoming increasingly popular. They’re highly resistant to corrosion and require minimal maintenance. This makes them especially suitable for coastal areas or properties exposed to harsh weather. Black steel look doors are also effective as a statement entrance door (see this case study for inspiration).

Best value internal doors
Materials and benefits

Door type	Definition	Characteristics	Approximate average cost
Laminate doors	Doors with a core of particleboard or engineered wood, covered with a decorative laminate surface. Laminate is a synthetic material, often designed to mimic the look of wood.	Affordable, durable, easy to clean and available in a range of styles and finishes. Less sound insulation than solid wood. Can look less authentic than real wood.	£30 – £100 per door (supply only)
Oak veneer doors	Doors with a core of engineered wood (like particleboard or MDF) and a thin layer (veneer) of real oak wood on the surface.	Offer the look and feel of solid oak at a lower cost. Good balance of aesthetics and affordability. Better sound insulation than laminate or moulded doors. Veneer can be susceptible to damage if not properly cared for.	£100 – £400+ per door (supply only). The price range is broad due to the variations in the quality of the veneer and the construction of the core.
Moulded doors	Doors made from a single piece of composite material, often MDF (Medium Density Fibreboard) with a moulded or pressed design on the surface to resemble panelling.	Budget-friendly, consistent appearance, pre-primed and ready to paint. Not as durable or sound-insulating as solid wood. Can look less luxurious than real wood options.	£40 – £150 per door (supply only)

Solid core internal doors
A worthwhile investment

Internal doors play a leading role in defining the layout and style of a property. They offer privacy, sound insulation and contribute to the overall interior design. But which which type of door is best for a home? Solid core doors rank highly for several reasons.

Their robust construction (featuring a dense inner core typically made of engineered wood or particleboard) provides superior sound insulation. The result? A quieter and more peaceful environment within the home. Particularly valuable for utility rooms, bedrooms, media rooms and home offices.

Solid core doors also offer enhanced security compared to hollow core alternatives, as they’re more resistant to forced entry. While they may be slightly more expensive upfront, their durability and longevity mean they’re less likely to need replacing. Ideal for saving money in the long run.

The added weight and substantial feel of a solid core door also contributes to a sense of quality and craftsmanship, enhancing the overall value and appeal of a new property.

Finding the best doors for outside

Shopping for the best patio doors is crucial for any renovation or property development project as they can also significantly impact the aesthetics and functionality of a space.

Patio doors serve as a bridge between indoor and outdoor living areas, influencing natural light flow, ventilation and overall ambiance. Selecting doors that complement the architectural style of the property while also meeting practical needs like energy efficiency, security, and ease of use is essential.

Choose between bifold doors, sliding doors and French doors in standard sizes or opt for bespoke made to measure patio doors. Standard colours include dark grey, black and classic white but custom RAL options are available to help achieve the perfect colour match.

The right patio doors can enhance the value of your property, create a more desirable living space and contribute to a feeling of synergy between inside and out. Conversely, poor choices could lead to draughty homes, security concerns and a visually jarring effect, ultimately detracting from the overall success of your project.
