Affordable Double- Storey House Extension Ideas for Semi- Detached Homes
Semi-detached homes in Liverpool offer great potential for extension—especially when you go up, not just out. If you're working with a tight budget, a double-storey extension can give you maximum living space at a lower cost per square metre.
At Leabra Construction NW, we help homeowners turn clever ideas into functional, affordable extensions that feel like part of the original home.
Why Semi-Detached Homes Are Ideal for Double-Storey Extensions
The shared-wall structure of a semi-detached home makes them cost-efficient to extend. With one less external wall to build and insulate, you save on construction and heating. These properties also tend to have more side or rear garden space to work with, making planning permission more achievable.
Affordable Design Ideas for Your Semi-Detached Extension
1. Rear Kitchen-Diner + Master Suite Above
Extend at the rear to create a modern open-plan kitchen-diner downstairs, with a master bedroom and ensuite upstairs. This classic layout balances family living with luxury.
2. Side Extension with Utility + Home Office
Use the side return to add a ground-floor utility room and a first-floor office or guest bedroom—perfect for remote workers or growing families.
3. Wraparound Double-Storey Extension
Go bold with a side and rear wraparound that completely transforms your floorplan. While it may cost more, smart material choices can keep it within budget.
4. Create a Lofty Landing Space
Use the staircase extension to open up the upstairs landing, letting in more light and connecting both storeys more naturally.
5. Use Skylights and French Doors
Add natural light with Velux windows or skylights, and bring the garden in with bi-fold or French doors—big impact with little budget increase.
