1.5 storey modular homes UK: a half-storey of bedrooms over the living space
A 1.5 storey house puts the bedrooms in the roof. The ground floor carries the kitchen, living space and a bathroom, and a staircase leads to rooms under the pitched roof, so the plot stays as compact as a bungalow while the accommodation grows. Both Trident models in this class are built on the closed-panel timber frame described on the technology page, with C24 structural timber and non-combustible basalt wool insulation, and arrive with combined timber and metal cladding and a metal standing seam roof included in the shell price.
Mediterranean Single House is the compact option: one bedroom, one bathroom, a kitchen-living room and a separate living room on a plot that would suit a garden annexe or a rental unit. Mediterranean Double House scales the same idea up to three bedrooms, two bathrooms and a sauna, for a family home or a holiday let. Both are published with from-prices across the three purchase options, Shell delivered, Shell + Assembly and Turnkey base.

Choosing a 1.5 storey modular home
Count the rooms, not just the area
The room schedules in the comparison table come from the catalogue. A 1.5 storey layout gives more rooms for its footprint than a bungalow of the same area, because the roof space works as a floor.
Check the staircase and headroom in the plans
Rooms under a pitched roof have sloping ceilings at the edges. Open the floor plans on each model page to see where the full-height space falls and where the stair lands.
Weathertight is included
For both models the cladding and the standing seam roof are in the Shell delivered price, so nothing further is needed to make the shell weathertight. Compare the three options on the model page or in the full price guide.
Planning and foundations
A residential home needs full planning permission; we can provide planning support. Foundations are required before delivery, and the Turnkey base option includes helical ground screws and the internal fit-out.
1.5 storey homes: common questions
What is a 1.5 storey house?
A house with bedrooms in the roof space above a full ground floor. The pitched roof gives usable rooms with sloping ceilings at the edges, so the footprint stays close to a bungalow’s while the accommodation grows.
Is the roof covering included in the shell price?
Yes. For both models the combined timber and metal cladding and the metal standing seam roof are in the Shell delivered price, so the shell is weathertight with nothing further to buy.
How many bedrooms do the 1.5 storey models have?
Mediterranean Single House has 1 and Mediterranean Double House has 3, counted from the catalogue room schedules.
Does the Mediterranean Single House suit a rental unit?
It is designed for a compact plot with the functionality of a full house: kitchen-living room, separate living room, bathroom and a bedroom upstairs. That makes it a common choice for a let or a garden annexe, subject to planning permission.
