Maisonette Projects

Maisonette projects

This archive brings together selected AC Design Solution maisonette projects, showing how split-level homes and flats can be altered, extended and improved through careful design, planning and technical coordination.

Maisonette projects often need a more detailed approach than standard house extensions because the works may involve shared structure, neighbouring flats, leasehold arrangements, fire separation, sound insulation, access and building regulation requirements.

For homeowners and leaseholders planning similar work, our architectural services cover early design advice, planning drawings, technical coordination and residential project support.

Planning and design for maisonettes

Maisonette projects can involve internal layout changes, rear extensions, roof alterations, new openings, staircase changes, garden access improvements and technical drawing packages. Design decisions around layout, daylight, privacy, structure, access and neighbouring impact can all affect how the proposal is developed.

Our house extension drawings service supports residential clients who need clear drawings for planning applications, permitted development checks or design development.

Where the maisonette includes ground-floor space or garden access, our single storey extension service may be relevant for rear or side addition proposals.

Building regulations, structure and party wall matters

Maisonette projects often require detailed technical information for building control, especially where the work affects structure, fire separation, sound insulation, ventilation, drainage, stairs or means of escape. Our building regulation drawings help develop the information needed for approval, detailing and site coordination.

Structural design may be required where walls are removed, steel beams are introduced, new openings are formed, floor structures are altered or the existing building is changed. Our structural drawings and calculations service supports the technical design of residential alteration and extension projects.

Where works affect a shared wall, floor, ceiling, boundary, excavation zone or neighbouring property, our party wall surveying support can help homeowners and leaseholders understand notices, procedures and neighbour-related issues.
