Structural design for changes to your home
Hamilton Structural Engineers helps Cambridge homeowners modify openings, stairs, floors, roofs, and supports. We assess how each change affects the existing house and develop structural details for the planned changes.
Detailed service overview
We help you change the house while understanding what supports it. Door and window openings, stairs, roof alterations, and changes to beams or posts need details suited to the existing construction.
You receive details for the change, including any related work to nearby framing or foundations.
Residential engineering services
Framing design for wider or taller window openings in existing walls.
Support details where a doorway changes the surrounding wall construction.
Design for cutting, moving, or changing an opening in a floor.
Assessment of the supports affected by a particular wall alteration.
Modifications to joists, beams, or other supports around the proposed work.
Review of whether an existing support can be moved, replaced, or reinforced.
Structural details for specific changes to the roof or its supporting construction.
We review the changes you want to make and the plans or information already available.
We review the building or site information and design the structural elements your project needs.
The agreed package explains the designed members, supports, and connections.
Any included permit responses, contractor questions, or design revisions are handled as the project progresses.
Homeowner questions
We assess structural changes involving doors, windows, stair openings, floors, roofs, beams, and posts. The design can cover a focused alteration without treating the whole house as a new build.
Size alone does not establish the effect on the structure. A small opening or relocated post can change important supports, so the assessment focuses on what the alteration affects rather than its floor area. Relocating a post slightly may change where a large load reaches the foundations.
That may be possible. We consider the space for a beam or header, the loads above, and the supports at each end before comparing details that could suit the preferred opening height. A preferred finish can guide the options, but does not determine the beam size.
It can. Cutting floor members transfers their loads to other framing and supports. The assessment follows the loads to nearby walls, beams, and foundations where relevant.
Both options can be assessed. Keeping a member requires checking its new role; moving it can change spans and foundation loads. A relocated post requires suitable support beneath its new position, not just a clear floor.
Their routes need coordination with the structural design and the relevant trades. The chosen opening and its connections need to leave workable space for surrounding services.
The structural drawings should describe the altered framing, connections, and supports needed for the work. Any concealed condition requiring confirmation should be identified before it is covered by new finishes.
The services overlap. A house modification may concern one opening or support, while a renovation can involve several connected changes. The same engineering principles apply whether the work concerns one support or several connected alterations.
Hamilton Structural Engineers provides structural design for house modifications for homeowners in Cambridge.
