What a design and build project involves

A design and build project for a two-storey extension involves one team taking responsibility for the whole job: the survey, design, planning or permitted development, structural engineering, building standards, party wall matters where they apply and the construction itself. You deal with one point of contact instead of coordinating an architect, engineer and builder separately. The design stage is priced first, then the build at a fixed price.

Lanarkshire towns we list: East Kilbride (G74), Hamilton (ML3), Cumbernauld (G67), Coatbridge (ML5), Airdrie (ML6) and Motherwell (ML1). Every other address in Lanarkshire is covered as well.

Fees

The design stage is priced in writing before it starts, and the build is a fixed price in writing once the design is agreed.

Rules in Scotland

In Scotland, design and build covers the Class 1B check or a householder application (£371), the building warrant from the council's building standards service before work starts, and the completion certificate at the end. There is no Party Wall Act, so we handle neighbour matters under common law and title deeds.

Approval in Scotland: Householder planning application: £371. Councils have two months to decide a local planning application.

Building standards: A building warrant from the council's building standards service before work starts, and a completion certificate at the end. Scotland uses its own Technical Handbooks.

There is no Party Wall Act in Scotland. Shared walls and boundaries are governed by title deeds and common law, so we speak to neighbours early and record the condition of shared structures.

Getting the design right

How the stages work

We start with a free site visit, then a design stage priced in writing before it begins. That covers the survey, design, approvals, structural design and building standards. Once the design is agreed, the build price is fixed in writing before work starts.

Cost checking as you design

Because the people drawing the extension also build it, each design option comes with a guide cost. That avoids the common problem of an approved design that turns out to be too expensive once builders price it.

How we work in Lanarkshire

Look at the house
We start in Lanarkshire with a free visit: measurements, photos, a look at the loft and drains, and a frank chat about budget.
Design and approvals
We draw the extension and check it against the rules for Scotland, then apply for planning permission or a certificate of lawfulness, whichever fits.
Engineer it
Foundations sized for two floors, steels for any openings, and a building warrant, all before anyone starts on site.
Build it
The new structure goes up first, then we open into the house, finish inside and get the completion certificate.

Design and build two-storey extensions in Lanarkshire: questions

Who builds my extension?

Your extension is built by vetted teams working under S&K, with the project managed by us from design to completion. You have one point of contact throughout, and the same team that prepared the design is responsible for the build.

Do I have to use you for the build if I pay for the design stage?

No. The design stage is priced separately, so you can take the approved drawings to other builders if you choose. Most people who use design and build carry on to the build, because the design has been costed as it developed.

When is the build price fixed?

Once the design is agreed and the drawings, structural calculations and specification are complete. Before that we give guide costs at each stage. The fixed price is set out in writing before work starts, and any changes you ask for after that are priced separately before they are made.
