IGD Building Services carries out house extensions and loft conversions across Surrey and surrounding areas. Based in Coulsdon, we can discuss your plans for a larger kitchen, additional living space or a new room in the roof.
We start with a site visit to understand your project, review any drawings and prepare a quotation for the agreed scope.

House extensions
We can discuss rear, side and two-storey extensions, depending on your property and the proposed design.
Our quotation can cover a building shell or a wider scope including internal finishing. We agree what is included before starting, with the work based on the project drawings and specification.
Depending on the agreed scope, the building work can include:
- Groundworks and foundations.
- Structural steelwork and alterations.
- Walls, roof construction and weatherproofing.
- Insulation, plasterboard and plastering.
- Plumbing and associated electrical work.
- Internal finishing and decorating.
We identify separately supplied items and specialist work in the quotation. Window and external door arrangements are agreed separately.
Loft conversions
A loft conversion can create space for a bedroom, bathroom or home office. The suitable design depends on the roof structure, available space, staircase position and the intended use.
We can review proposals for rooflight, dormer, hip-to-gable or mansard conversions with you and the relevant professionals. The construction scope is agreed from the drawings and specification.
If your project includes a new bathroom, see our bathroom renovation page for more information about that part of the work.

Drawings and approvals
During the site visit, we review the information available and discuss what is needed before construction can begin.
We work to the agreed architectural and structural drawings. Planning, building control, fire safety and any party wall requirements need to be addressed for the specific project with the relevant professionals.
If you already have drawings or approvals, let us know when you enquire.
Planning the building work
Before work starts, we agree access, deliveries, protection for retained areas and the expected stages of construction. We also discuss how the work will affect you if you plan to remain in the property.
Removal and disposal of waste generated by our work is included.
Our quotation sets out the agreed scope, materials and fittings, specialist arrangements and payment stages.
Like-for-Like Price Promise
For house extensions, if you receive a lower written quotation from another reputable builder for the same scope and specification, send it to us for review. We will compare it like-for-like and do our best to beat the price where possible.

Extension and loft conversion questions
What do you need to prepare a quotation?
Send us your property location, a short description of the space you want to create and any architectural or structural drawings you already have. We arrange a site visit to review access, the existing building and the proposed work before quoting for the agreed scope.
Can you quote for a shell or a finished extension?
We can discuss either approach. The quotation identifies the construction work and any agreed internal finishing, so you can see which materials, fittings and specialist items are included and which are arranged separately.
What affects the cost and construction programme?
The size and design, foundations, structural alterations, site access and chosen finishes all affect the work required. We discuss the programme and payment stages after reviewing the project information; changes to the specification are agreed before additional work proceeds.
