Key Decisions to Make During a Home Renovation Project

Planning a home renovation or extension involves far more than approving drawings and hiring a builder. As the project progresses, homeowners need to make a number of important decisions that affect the appearance, function, and timeline of the build.

From flooring and lighting to doors and heating systems, these choices help shape the final result of your home.

Making decisions early helps prevent delays caused by product lead times and ensures your renovation runs smoothly from start to finish.

In this guide, we outline the key decisions homeowners typically make during a home renovation or extension project. 

 During most renovation projects, homeowners will need to choose:

• Internal doors and joinery 
• Paint colours and wall finishes 
• Flooring materials and layouts 
• Lighting and electrical fittings 
• Heating and plumbing fixtures 
• Kitchen design and appliances 
• Bathroom layout and fittings
   

Providing these decisions early helps maintain the construction schedule and avoid unnecessary delays.

 Internal doors and joinery details influence the overall style of your home and should be selected early in the project.

Key decisions include:

Common options include:

• Shaker doors 
• 4-panel doors 
• Solid oak doors 
• Primed doors ready for painting 
• Fire-rated doors where required
   

You will also decide whether doors should be painted or varnished.

You may need to confirm:

• Which direction the door swings 
• Whether it opens into or out of a room 
• Left- or right-hand hung doors
   

Ironmongery choices include:

• Handle style
• Finish (chrome, brass, black, brushed steel) 
• Lock type such as latch, privacy lock, or key lock
   

Hinges should match the finish of door handles and may be standard or ball-bearing types.

These finishing trims frame doors and floors.

Common profiles include:

• Torus 
• Ogee 
• Square edge
   

Homeowners also choose the height of skirting boards, often between 100mm and 150mm. 

Paint colours and finishes help define the overall look and atmosphere of your home.

Some homeowners prefer specific brands such as:

• Farrow & Ball 
• Dulux Trade 
• Little Greene
   

Always provide the exact colour name and code to ensure the correct shade is used.

Different surfaces require different finishes.

Typical choices include:

Walls

• Matt
• Eggshell 
• Scrubbable finishes for high-traffic areas
   

Woodwork

• Satin 
• Gloss 
• Eggshell
   

Ceilings

• Usually flat matt white
   

If wallpaper is being used, you should confirm:

• The exact product
• Which walls it will be applied to
   

Some bespoke wallpapers can have longer lead times.

Flooring is one of the most visible design decisions in any renovation project.

Popular options include:

• Carpet 
• Luxury Vinyl Tile (LVT) 
• Engineered wood 
• Stone or porcelain tiles
   

For carpets and floating floors, underlay thickness and sound-reduction performance may need to be considered.

Some flooring materials allow decorative layouts such as:

• Straight plank installation 
• Herringbone pattern 
• Chevron pattern
   

Transitions between rooms must also be chosen.

Common options include:

• Oak threshold strips 
• Metal trims 
• Z-bars for carpets
   

For tiled floors, grout colour and spacing should also be confirmed.

 Lighting and electrical layouts should be carefully planned so they suit how you use each space.

You will need to choose the finish and style of switches and sockets.

Examples include:

• White plastic 
• Brushed steel 
• Brass 
• Screwless modern plates
   

Switches may include:

• Standard rocker switches 
• Dimmer switches 
• Decorative toggle switches
   

Lighting choices usually include:

• Recessed downlights 
• Pendant lights 
• Wall lights
• 
  

You may also need to confirm light temperature, typically:

• Warm white (2700K) 
• Cool white (4000K)
   

Consider where sockets should be positioned and whether USB sockets are required.

If televisions will be wall-mounted, it’s best to decide early so cables can be hidden within the wall.

 Heating and plumbing fixtures should be selected early, especially for bathrooms and kitchens.

Options include:

• Standard compact radiators 
• Column radiators 
• Vertical designer radiators
   

Valves may be:

• Manual valves 
• Thermostatic radiator valves (TRVs)
   

Homeowners typically choose between:

• Deck-mounted taps 
• Wall-mounted taps or shower heads
   

Wall-mounted fittings often require early planning during construction.

Sealant colours are usually chosen to match grout or surrounding finishes.

 If your renovation includes a new kitchen, the layout should ideally be designed before construction begins.

Kitchen design often involves collaboration between:

• A kitchen supplier’s designer 
• An architect 
• Your building contractor
   

Planning the kitchen early ensures plumbing, electrical points, and appliance locations are properly coordinated.

 Bathroom layouts should also be designed early in the project. Working with a designer helps ensure:

• Plumbing locations are correct 
• Fixtures fit the available space 
• Tiling and waterproofing are planned properly
•  

Finalising these decisions early helps prevent costly changes during construction. 

 Many renovation delays occur because materials or finishes are chosen too late.

A typical timeline might look like this:

Design Stage

• Kitchens 
• Bathrooms 
• Layout decisions
   

First Fix Stage

• Electrical layouts 
• Lighting positions 
• Plumbing locations
   

Second Fix Stage

• Doors 
• Flooring 
• Paint colours 
• Fixtures and fittings

Ordering materials early helps avoid delays caused by manufacturing or delivery lead times.
