Gulf Builder team preparing structural timberwork for a space conversion
04 / Basement & Conservatory

Unused space. Proper purpose.

Basements and conservatories rebuilt for everyday use.

Gulf Builder coordinates structural work, weatherproofing, insulation and internal finishes to turn underused areas into comfortable, practical rooms.

The brief

Structure, weather protection and finish managed together.

Converting a basement or conservatory starts with the parts that control comfort: a sound structure, moisture management, insulation and reliable services.

Our team plans those stages together, then carries the room through to plastering, joinery and decoration under one clear programme.

Project journal / London

Building a dry, insulated and usable room.

The project moved from survey and structural preparation through roof detailing and internal enclosure as one coordinated conversion.

FIG. 01 / ROOF SURVEY
Existing roof surveyed before Gulf Builder conversion work
The existing structure was inspected before the new build-up and weatherproofing work began.
FIG. 02 / EXISTING STRUCTURE
Existing structure assessed during a Gulf Builder conversion
The original roof and junctions were checked to define the correct structural repairs.
FIG. 03 / EXTERIOR WORK
Exterior preparation completed by Gulf Builder
External access and working areas were prepared before the main conversion stages continued.
FIG. 04 / ROOF DETAIL
Roof junction detailed by Gulf Builder
The roof junctions were rebuilt carefully to create a secure and weather-tight connection.
FIG. 05 / WEATHERPROOFING
Weatherproof roof preparation by Gulf Builder
Membranes and coverings were installed in sequence to protect the new enclosed space.
FIG. 06 / INTERNAL SHELL
Internal ceiling shell prepared during a Gulf Builder conversion
The internal shell was prepared for insulation, services and the final room finish.
How we build

A controlled route from underused space to finished room.

01

Survey and diagnose

We assess structure, moisture, access and the intended use of the room.

02

Build the shell

Structural repairs and weatherproof elements create a secure enclosure.

03

Insulate and service

Insulation, electrics, plumbing and ventilation are coordinated together.

04

Finish and handover

Plastering, joinery and decoration complete the space ready for use.
